Trimmer from the engine of the washing machine. Utopia or reality: do-it-yourself lawn mower from a washing machine. How to make a lawn mower with your own hands from available materials
Perhaps a mower in household can not be called essential equipment. But for giving it is an indispensable tool. Owners of personal plots, looking at the high cost of lawn mowers, are increasingly thinking about how to assemble such a device on their own from improvised materials. Today we will figure out how a lawn mower is made from washing machine with your own hands.
The first steps
First you need to prepare everything you need to install the lawn mower. If it is decided to make it from an old washing machine, then we will need:
- wheelbase - you can use a trolley or a baby carriage;
- steel sheet, the thickness of which varies between two to four millimeters;
- tool steel knives;
- water pipe. It will make a handle for a lawn mower, and its diameter should be suitable (thin);
- electrical cable with plug;
- switch.
The engine is an important element, and when choosing it, certain factors must be observed. Let's imagine that a motor with a start relay and a 180 W capacitor is best suited. It can be taken in the simplest washing machine, and it will be better if it turns out to be an old model, since the solid weight of the element will come in handy.
Wheels, if there is no old stroller, can be made independently from plywood sheet and bearings. When mounting them, it is recommended to maintain a distance to the ground of five to six centimeters, corresponding to the height of mowing. You choose the number of wheels yourself so that the lawn mower gets sufficient stability and moves easily. The best option is four wheels, but many, in order to save money, install only three, which does not affect the performance. You can use only a pair of wheels, which will ensure quick maneuverability.
A sheet of metal is also not randomly selected. Its dimensions are taken into account, which should be thirty by fifty centimeters.
The frame, as a rule, arranges a width of 30 by 50 cm, which is the best solution. Do not overdo it with depth - make sure that the engine does not crawl out of the boundaries, and this will be quite enough.
For the manufacture of knives, mild steel with a thickness of 2 to 3 mm and a width of 2 to 5 cm is used. Note that the metal should not be brittle. As an example, let's take a saw blade for wood.
Making an electric lawn mower
The assembly does not cause any particular difficulties, if you act in accordance with the developed plan. At successful option you can assemble a lawn mower with an engine from a washing machine within one day.
First, we install the base in the form of a metal sheet on the wheelbase. From the pipe we arrange a handle. It is desirable that its shape resembles the letter "P", and the height corresponds to your height. The finished handle must be welded to the steel platform.
At the base we prepare a hole for the shaft of the electric motor. On the front of the frame, you will have to arrange protection in the form of an arc or a soft metal grille. This is necessary in case the knife suddenly breaks off the shaft.
The electric motor is installed on the platform. A knife, previously sharpened, will have to be fixed on the shaft.
We assemble a lawn mower from a washing machine with a grass collector
To make such a model, you will have to perform the following algorithm of actions:
- a platform for an electric motor is being prepared from a steel sheet, the size of which is 500 by 500 mm;
- in the center a hole is made for the motor shaft from the washing machine;
- from the bottom of the square base around the entire perimeter, a metal corner is welded (you can fix it with bolts);
- wheels are mounted on metal scarves. By the way, they are allowed to be connected with steel axles;
- the engine is installed on the platform. If it is flanged, holes are drilled in the base, in the usual one, corner racks for paws equipped with special slots are welded;
- the control handle is attached;
- a casing from the cover of an old washing machine is installed under the platform;
- installed homemade knife on the motor shaft. Below it is a simple tin protecting the shaft from vegetation.
The assembly of the mechanical part is completed. It remains to assemble the electrical circuit of the lawn mower. For this:
- a switch is installed, which should be fixed in a convenient place in relation to the handle;
- an electrical cable with a plug is connected;
- installed RCD.
The final stage is the installation of a grass collector made in the form of a box or bag. The casing should cover the knives and the electric motor, which will increase the level of safety and create protection from moisture and debris.
Learn more about lawn mower blade
The quality of work and the operating period of the lawn mower depend on this important detail. The knife is made in two versions.
Whole
Outwardly, it resembles a plate, the working surface of which is sharpened along the entire length, and there is a hole in the center. The plate is made of durable steel.
If the knife has two blades, it should be balanced to eliminate vibration that could destroy the electric motor shaft from the washing machine. In order for the knife not to dull quickly, an angle of sixty degrees is maintained during sharpening.
To ensure that the mowed weed is laid evenly, the back of the knife is bent according to the propeller principle. Before processing, the steel is “tempered” for gas burner and hardened again, after which it can be sharpened.
Since the mechanical part of a homemade lawn mower operates in extreme conditions, the shaft must be protected to prevent winding of the cut grass.
This version of the knife works fine until it hits a stump or stone.
Composite
Steel for its manufacture may not differ in hardness, the working surface is not sharpened to its full length, but in five-centimeter segments. From a sudden blow, the blade will simply bend at a right angle, the knife, and the motor shaft will not suffer.
This is how fastening works. propellers boat engine - only the key suffers from a collision.
The shape of the knives can be curved, curly, trapezoidal. Their length should not exceed fifty centimeters. An unusual version of the knife is represented by a solid disk.
Safety regulations
When assembling a lawn mower with an engine from an old washing machine with your own hands, do not forget about safety. Remember that it is forbidden to use such a lawn mower during rain or wet grass.
A self-made product cannot be compared with a factory counterpart, and insulation can fail at any time.
Do not pass a working lawn mower to small children.
If the blade jams during mowing, do not deal with the problem until the mower is de-energized.
Conclusion
A lawn mower powered by a washing machine engine can be assembled at home. The design of the device is simple and efficient, no additional costs are required. Note that the craftsmen came up with a large number of different models lawn mowers that differ in external data and the complexity of installation.
Advanced models are equipped with a special mechanism that regulates the height of the legs above the ground. In addition, with the release of the power button, you can quickly turn off the engine.
In addition, from a used washing machine, you can also construct:
-
-
-
- electric bike,
-
-
-
- concrete mixer,
- lathe,
I asked myself a lawn mower, it’s a little expensive to buy, and it’s a pity to spoil a good mower (I have a lot of stones, bricks and gravel on the site after the construction).
I’ve seen enough videos about homemade products and go ahead, just on the balcony an old stroller is lying around, I took the chassis and handle from it and recycling at work full swing goes (from there I removed 2 motors) and went to make.
Everything used was available and free of charge except for the M16 stud and 10 nuts for it, which is 200 rubles after all ... The stroller chassis is made to last from a thick bar, not like a modern one from thin tubes, it’s scary to pick up. I scalded the frame in a circle (except for the front) with 1mm sheets.
then he welded a pulley from the grinder to the motor pulley and took the nut washers from it. The motor is mounted on 2 M16 studs, they also regulate the cutting height by clamping the motor with nuts. Alas, I didn’t take a photo, because time is not enough.
Next, I found a motor connection diagram on the Internet, there are a lot of them. I didn’t make any switches, I just plugged it in and went to mow. The knife is cut from a 2mm metal plate, the width of the grinder washer, sort of like 50mm and 38cm long. balanced on the edge of the sheet 1mm, putting the center of the hole and grinding the outweighing edge. Like everything, there will be questions, ask.
That's how it works, mows well, cheerfully and evenly. When a brick or large stone hits, the knife bends into a donut. We remove it with a right hammer, sharpen again, balance and back. While mowed, he did the procedure three times. I would have gone bankrupt on purchased knives.

Here you can see protection from all sides except for the front, the knife is made of a sheet of metal. Looking closely, you can see serrations and dents on it from stones that come across on the site, and there are sooo many of them ... For convenience, I welded an ordinary nut to the Bulgarian nut, very often you have to remove the knife to sharpen and straighten until the site is cleared of stones and bricks.
Here the knife is still straight, a little later I twisted it with a propeller, the effect of this pleased me. Mowing became smoother, porridge from grass crawled out from under the mower.

How to make a lawn mower from old tools and household appliances with your own hands
Lawn mowers are used for lawn maintenance, lawn decoration in front of the house. There are a wide range of these devices in stores, but they are expensive. Therefore, you can make a lawn mower with your own hands.
You can make a lawn mower with a gasoline or electric engine. Gasoline is used for large areas, they are not tied to electrical power. On small summer cottages with a small amount of work, electrical devices are used. The unit consists of the following elements:
- motor;
- control lever;
- corps;
- knives.
The engine is mounted on the platform, the cutter - under it. The handle and lever are attached to the platform itself. Self-propelled homemade mowers will keep the lawn in excellent condition.
From the washing machine
A home master, if desired, can create a lawn mower with his own hands from a washing machine. An inexpensive lawn mower from a washing machine includes the following parts:
- steel knives;
- cart wheels;
- pipe for the handle;
- electric wire;
- switch;
- fork.
For the manufacture of homemade products, you can use a 180 W motor with a capacitor and a start relay. This motor is taken from the washing machine. It is worth picking up or making wheels from plywood. They should be placed at a distance of 5-6 cm from the soil surface.
This distance is the height of the grass mowing. The number of wheels is 4, 3, 2. The sheet should have dimensions of 30x50 cm. Knives are made of steel 20-50 mm wide, 2-3 mm thick. The cutting side is slightly bent downwards, this will protect the shaft from debris and grass. The handle is made by bending the pipe to make it convenient to support the unit. The handle is attached to the frame by welding.
A platform made of sheet is installed on the chassis from the trolley. A handle is made of pipes and fixed to the platform by welding. Make a hole for the motor shaft. A protective steel grille is welded on the front of the frame. The top and bottom of the grille are screwed on, and the wire is welded to them.
The electric lawnmower grate provides clearance for the blade. The engine is fixed on the platform, its shaft must pass into the cut hole. A cutter with sharpened teeth is placed on the shaft. A hole is drilled in the middle.
The knife must be balanced and centered. The engine is covered with a casing to protect it from grass. Since the motor must be cooled during operation, holes are provided in the casing.
Now connect the wiring to the motor and fix it. The metal handle must be wrapped in a rubber casing to protect it from electricity.
You can also additionally make a grass collector for a lawn mower with your own hands.
From Bulgarian
A cheap do-it-yourself lawn mower from a grinder is created as follows. The body of the device is made from a car disk. Saw the disk into 2 parts. A lid is welded to one part.
Then, an opening is created in the side of the disc, where it will be in front of the mower. Attach wheels and a handle to the body. Holes are made in the casing of the grinder or trimmer. The device is fixed to the body of the lawn mower with screws. The knife can be made from steel. Its edges are sharpened on a sharpener and unfolded in the form of a propeller.
The cutting element is attached to the grinder shaft. A nut is screwed onto it. The cutting device is screwed with a bolt fixed in a nut. The switch on the grinder is fixed wooden block. A switch and a plug are installed on the mower handle so that an extension cord can be connected.
From a vacuum cleaner
An inexpensive homemade lawn mower from a vacuum cleaner is made as follows. You can remove the electric motor from the old vacuum cleaner and use it to create a homemade product.
We assemble a lawn mower with our own hands
Regular lawn care stimulates the growth and development of green cover, making the grass thicker and more even.
Mowing a lawn without additional tools is difficult, especially if it is not a patch around the house, but a spacious lawn.
In order not to buy ready-made equipment, you can assemble a lawn mower with your own hands. In the article we will describe in detail how to make it out of a failed washing machine.
How the mower works
Electric mowers are quite simple in their device. All mechanisms are connected in a certain order, which ensures stable operation.
The simplest electric trimmer model
Rotor mechanism drawing
The design of a homemade lawn mower: 1 - knife; 2- support frame; 3 - protective visor; 4 - wheels; 5 - motor mount; 6 - electric motor; 7 - switch; 8 - handle; 9 - flange for attaching a lawn mower blade; 10 - lattice
The package includes the following items:
- electric motor;
- frame;
- knife elements;
- chassis;
- control handle.
The motor is fixed on the wheel frame, a deck is attached to its lower area, a handle is installed on one side.
Motor mount
Unlike a self-assembled lawn mower from a grinder, factory modifications meet the safety and convenience rules, in addition, they can have the following components in their design:
- grass catcher;
- mulching mechanism;
- protective device against wear of knife elements;
- handlebar with height adjustment function.
Before you make a lawn mower with your own hands, you need to understand the principle of operation, which in this case is the same for all devices. The motor drives the output shaft, it also produces revolutions and transfers them to the cutting parts. This is how lawn mowers from Druzhba chainsaws, washing machines or factory devices function.

Which engine to choose
The type of power unit directly depends on the area planned for processing, its relief. As a rule, home craftsmen do not go over the options and use any motor that is in electrical engineering or household equipment. For a do-it-yourself lawn mower, the following options are suitable:
- engine from a washing machine;
- trimmer motor;
- vacuum cleaner;
- electric drills;
- Bulgarians.
Also, a gasoline power unit from a chainsaw will serve as an excellent basis. The most optimal motor is an asynchronous type, capable of producing more than 3000 revolutions per minute. The higher will be given value, the better it will be to cut a do-it-yourself lawn mower from a chainsaw, trimmer or other equipment.
For an electric one, a drill with a speed of 1500-3000 rpm is quite suitable.
Knife device - material and shape
The easiest to manufacture and most effective option is a two-blade horizontal type knife.
Knife fastening unit: a) - bushing; b) - single knife; c - double when installing the engine at least 2850 rpm.
To make it you need:
- prepare a steel bar with dimensions corresponding to the grip of a homemade mower - 300-500 mm and a width of 2-5 cm;
- on the frontal part, you yourself need to sharpen at an angle of 60o;
- the back part is bent a few millimeters.
Such a lawn mower scheme will allow you to create a uniform haircut and laying of cut grass.
Body part and mowing shield
The frame of the device will simultaneously serve as a frame for the knife element and a housing for all equipment. Most in a simple way equipping a homemade lawn mower with a body will serve as a ready-made version:
- large frying pan;
- pelvis with shallow depth;
- the bottom of the saucepan.
In the prepared lawnmower blade, it is required to create a hole for mounting the motor shaft.
Wheel and handle dimensions
The diameter of the wheel installation directly depends on the relief of the plantation and the required cutting height. Masters landscape design claim that the most optimal value for lawn is 50-60 mm. It should also be noted that when setting a large parameter, the grass is mowed unevenly, and otherwise, the passage of a lawn mower with small wheels will be difficult.
Wheel, lattice and ski design
As for the number of wheels, they are chosen solely at the request of the master. But here are some important factors to keep in mind:
- 3-4-wheel modifications are the most stable on different terrains, while they provide the same cutting height, which makes the lawn equally trimmed;
- homemade lawn mower from a chassis with two wheels - a maneuverable option that allows you to mow grass on difficult areas, but here you need to create a special frame drawing that will protect the knife from contact with the ground;
- The 3-wheel version, where two wheels are closer to the operator and one in front, is less stable, but more agile.
Circuit connection diagram
The handle is also made by hand. It is enough to weld pipes with a diameter of 2-3 cm. You can also borrow a handle from an old cart.
Do-it-yourself lawn mower from a washing machine
There is an option how you can make your own lawn mower from a washing machine. The converted model will easily cope with a plot of up to 5 acres. But here it should be noted that such a device does not tolerate increased loads, therefore, in the process of operation, it must be periodically disconnected from the network.
What details are needed:
- asynchronous type electric motor - a motor from a Soviet washing machine with a power of more than 200 W is perfect;
- semi-automatic washing machine switch;
- wheels with a diameter of 100 mm;
- steel bar with a width of 5 cm and a length of 300-500 mm, depending on the width of coverage;
- steel sheet with parameters 30x50 cm;
- profile socket for the handle;
- steel corner for the frame;
- 3-core electrical wire with plug;
- fasteners - nuts, bolts and studs.
As a washing machine, only the electric motor is meant to be used together with the start relay.
In addition to the details for creating an electric lawn mower with your own hands, you will need to prepare the tools:
- keys of all types and sizes;
- electric drill;
- welder;
- multimeter;
- pliers;
- Bulgarian;
- soldering machine;
- a hammer;
- level, etc.
Stages of work
From metal corners, you need to weld the frame, taking into account the width of the knife element. Make a hole in the platform through which the engine shaft will exit.
On two parts of the frame, you need to fix the running racks and attach the platform to the base. Next, an arc is mounted on the front side of the case, which will act as protection for decorative garden plants from a random cut.
On a metal piece, the boundaries of the cutter should be marked, after which, according to the drawing, it is required to sharpen the cutter of the blade. Further, a hole is drilled in the center for fixing to the motor shaft.
Choose the most suitable height, approximately 90 cm and, based on these data, cut the metal pipes, weld a U-shaped handle from them. It is recommended to wrap the working part with insulating tape or put on a rubberized casing.
Wheels must be attached to the side parts of the chassis. The power unit is mounted on a platform, while the shaft must exit through the hole to the base of the homemade lawn mower. The knife element is fixed to the shaft, it must be carefully centered and balanced so that as a result of work it cannot warp.
The motor is covered with a protective casing, in which several holes are required to prevent overheating. Connect the electrical wire to the engine, check all connections for continuity and try the first start.

How to make a lawn mower with your own hands
Today, the market for electric and gasoline lawn mowers can provide a large number of various options and models.
But in the case when there is no budget for a mower, but you don’t want to mow it manually, then you can make a lawn mower with your own hands at home from improvised parts and materials.
A do-it-yourself lawn mower will significantly save money, unlike factory counterparts.
Necessary materials and tools
A device such as a do-it-yourself electric mower is not a basic necessity. But the presence of such a tool at home will significantly save labor costs when mowing grass. Very simple lawn mowers can even be made from an electric motor. They include the same parts and functionality as the factory counterparts.
Electric lawn mowers include:
- an electric motor or drive mechanism that rotates the blade attachments;
- the basis of the frame on which all the details of the mechanism will be held;
- protective shield;
- a handle with which the mechanism is controlled;
- blade knives;
- 2-4 wheels;
- button on and off the mechanism;
- power cable;
- a container for collecting grass or removing it.
All electric mowers work in the same way. After applying voltage to the electric motor, its shaft begins to rotate. And since the knives are fixed on the shaft, they cut the grass at high speeds of the electric motor.
Selecting the right engine
As a motor for a lawn mower, you can use the engine:
- from a vacuum cleaner;
- from the washing machine;
- from Bulgarian;
- from the trimmer.
If you need to mow small areas, then just right there will be an engine from an old drill. It does not even need to be disassembled, just fix it in a vertical position.
A do-it-yourself lawn mower from a washing machine or a Soviet-style vacuum cleaner can be made without much effort. They have all the necessary details.
The best option for mowing grass near the house, an electric motor with a power of 0.5 kilowatts is considered, and the recommended speed is about three thousand.
The quality of work and grass mowing depend on the speed of the motor, and accordingly its blades.
The longer the knives of the device, the lower the number of revolutions it can be used due to the increase linear speed. But its power must increase in order to deal with the increasing load.
In practice, it has been proven that for domestic needs a device with a power of one kilowatt and an engine speed of one and a half thousand is enough. Moreover, the working plane is half a meter.
In the event that the engine power is less than these indicators, then the blades need to be sharpened regularly to obtain the desired result.

Do-it-yourself lawn mower from a washing machine - manufacturing procedure
The emerald lawn is an excellent decoration for a suburban area, but without care it quickly turns into impenetrable thickets.
A lawn mower is required and if an old household appliance with a motor is available, the device can be assembled by yourself. Next, we will tell you how to make a do-it-yourself lawn mower from a washing machine.
Design
A lawn mower, due to various options, can have a complex device, but basically it is just an engine with a knife put on its shaft, mounted on a chassis with a handle. It happens that the shaft with a knife is installed separately and connected to the engine shaft by a chain or belt drive.
Two types of engines are used:
A lawn mower equipped with an electric drive has a number of advantages:
- works silently;
- no exhaust;
- no need to store fuel and waste time refueling.
An electric mower is the preferred option for lawns up to 12 acres.
The platform on which all nodes are installed is called the mowing shield. From below, it has sides that do not allow the grass to scatter in all directions.
According to the number of wheels, lawn mowers are divided into:
Do-it-yourself lawn mower to the country
The dimensions of the wheels and other elements are selected so that the knife is located 5 - 6 cm above the ground - then the cut will be even.
To control the lawn mower, a handle is attached to the chassis.
Unlike a purchased one, a home-made mower cannot be made self-propelled and equipped with mechanisms for collecting grass and adjusting the cutting height. But she will successfully cope with the main function.
Necessary tools and materials
The arsenal is:
- welding machine with electrodes;
- drill with drills for metal;
- Bulgarian;
- soldering iron;
- spanners;
- screwdriver;
- roulette, ruler;
- core and scriber;
- marker or pencil.
Also need materials:
You will also need a steel equal-shelf corner with an arbitrary shelf width.
Process of creation
The manufacture of the lawn mower begins with the extraction of the electric motor from the washing machine.
Preferred engines:
- powerful;
- heavy (provide stability);
- asynchronous type (do not make noise).
These requirements are most satisfied by motors from Soviet-made washing machines, and even better - from centrifuges.
If the engine is low-power, the shortest knife is installed: the long one will cut the grass evenly only if it is constantly undermined.
cutting part
A homemade mower can be equipped with a purchased knife - this will not greatly affect costs. If it is decided to do this element with your own hands, consider the following:
There are two knife options:
The second option is more difficult to implement, but has advantages:
- costs less;
- when hitting a stone, one bolt is sheared and the cutting part is bent, while a full-blade knife in such a situation can damage the shaft and motor.
Equipped with lawn mowers and knives in the form of a disk. When meeting with a stone, they do not break, but only become dull.
Pen
As such, you can use one of the following elements:
- stroller handle;
- plastic water pipe;
- a cutting from an agricultural tool.
From these elements, a U-shaped structure is assembled.
The optimal length for a user with an average height is 90 cm.
A rubber hose is put on a metal handle in the grip area for the purpose of electrical insulation. At the top, in close proximity to the user's hands, an emergency button is attached for an emergency stop of the motor.
Electrician
To start the engine, it is best to use the "native" control system from the washing machine.
In its absence, for asynchronous motors, the same starting scheme is used as for conventional single-phase motors: with the help of a starting capacitor, the windings are connected to each other.
Capacitor and other components electrical circuit it is advisable to place them in a plastic box where they will be protected from dust and pieces of grass.
A regular plastic bottle can serve as a blank for such a box.
Assembly process
When making a homemade lawn mower, proceed in the following order:
The lawn mower is ready, you can start testing.
Safety
The probability of an accident for a homemade lawn mower is higher than for a branded one, so it is recommended to follow these rules:
Check your lawn for rocks, toys, and other items before mowing.
Lawn mower with a washing machine engine - how to make
Does your lawn need constant maintenance? Then you can not do without a lawn mower. But, going to the store, you realize that this technique is quite expensive.
You do not need to overpay, because in this article you will learn how to make a homemade lawn mower from a washing machine. Namely, from the engine of the washing machine. Consider what materials will be needed for the job and how to create an effective lawn mower.
Lawn mower with an engine from an old washing machine
All lawn mowers are divided into two types:
- Petrol. Used for processing large areas. They are productive, noisy, and also create emissions during operation.
- Electrical. Much more environmentally friendly, but their movement around the site is limited by the length of the network cable.
The efficiency of work and the amount of cut grass will depend on the height of the base and the quality of the knives.
Of course, a homemade lawn mower lacks some of the advantages of proprietary technology. For example, the ability to collect grass, adjust the height of the lawn mowing. You will have to independently move it around the site, collect grass.
At the same time, without paying a penny for the device, you will receive a well-groomed and neat lawn.
Tools and Parts
Before you make a lawn mower with your own hands, you need to prepare everything you need:
- Washing machine engine. Suitable for both 180W and 500W motors. The more powerful it is, the more efficiently the device will cope with the work. The use of an asynchronous motor will allow you to work much quieter.
- Low wheels. You can use plastic wheels from a wheelbarrow or from a stroller - 4 pieces.
- For the base, a sheet of metal or steel is useful. You can also use a shallow basin, so that the grass will not scatter in different directions.
- Knives can be used from a branded lawn mower, or you can make your own from steel strips - see the next paragraph for how to do this.
- Profile pipe for the handle. You can use the handle from the stroller, the main thing is that the pipe is not heavy.
- Metal corners for the manufacture of the frame.
- Copper wire with three strands. The length depends on the size of the lawn.
- The switch can be taken along with the motor from the washing machine.
You will need these tools:
- welding;
- socket and wrenches;
- Bulgarian;
- drill;
- burner;
- pliers;
- a hammer;
- screwdrivers;
- nuts, bolts, screws.
Features of making a knife
The performance and efficiency of the lawn mower depends on the quality of the blade. You can make two types yourself:
Using a burner, the back side of the plate is bent, which contributes to uniform mowing.
To prepare the base, it is advisable to use the chassis from a stroller or trolley. Then it is enough to fix the canvas on them. But if there is no chassis, the corners will be used, which will turn into a frame with the help of welding. Frame dimensions 2.5 x 2.5 cm.
Now do this:
- Four racks for wheels are welded to the fabricated frame.
- In addition to the base, a pipe or profile is attached, curved in the shape of the letter "P".
- A hole is being prepared for installing the engine. To do this, a hole is cut in the base into which the motor is lowered with the shaft down.
- A grille is installed in front of the frame. It will prevent the knife from slipping off the shaft, and will also allow you to mow the lawn smoothly.
- A homemade knife is mounted on the motor shaft.
- A handle is attached to the base. A switch is mounted on the handle for convenience.
- A cable is connected to the engine, its other end with a plug is connected to the network.
As you can see, you can make a lawn mower with an engine from a washing machine yourself. This is a simple and effective design that will not require additional costs from you.

Homemade lawn mowers - learning to create from different tools and basics
Lawn mowers are one of the most cost-effective and practical lawn care products today. Therefore, it is not surprising that many people are trying to create a really high-quality and uncomplicated device with their own hands. Moreover, in the process it is possible to form an improved variation of the classic mower, supplementing it with details from other equipment.
Today, for the design of the specified unit can be used:
- Old vacuum cleaner;
- Unnecessary washing machine;
- Bulgarian;
- Chainsaw, etc.
Despite the fact that these machines are used in different areas and for other needs, with a little “conjuration” on them, you can get a really high-quality homemade product.
How to make a mower with your own hands?
As mentioned earlier, you can create a lawn mower:
FROM AN OLD VACUUM CLEANER
Carrying out such a procedure is quite simple, the main thing is to be patient and the following elements:
- wheels (suitable even from an old stroller);
- welding machine;
- hand saw;
- steel sheets;
- electric motor.
It should be noted that for better maneuverability and patency of the final product, it is desirable to use large diameter wheels. Thanks to them, the unit will not get stuck in every hole or slow down due to small stones.
A special platform should be cut out of the steel object, because it will play the role of a mounting support for the engine, whose shaft should be placed in the lower area. After making the installation, as in the above video, it is necessary to create a reliable protective casing for the engine.
The thickness of the “shell” should be 1.2 mm, and as for the diameter of certain holes of this protector, it should have a higher coefficient than the shaft, literally by 4 mm. The propulsion system must be marked at a distance of 3-4 cm from the ground, otherwise the part will be damaged during movement and operation.
Particular attention should be paid to the metal disk that is mounted on the shaft itself. Knives need to be created in several versions. To do this, the master must cut a disk from an iron sheet (the dimensional coefficient of which is 38-40 mm). It is placed at the motor end and carefully welded with a welding machine.
FROM THE WASHING MACHINE
To create a homemade mower, the following elements are ideal:
- engine from an unnecessary washing machine;
- wheels from an old baby carriage;
- sheet of metal (thickness 2–4 mm);
- steel knives;
- thin water pipe (future handle)
- electrical cable;
- fork;
- switch.
The lawn mower itself is not extremely complex, because it contains a reliable body, sharp knives, a powerful engine and a well-placed control lever. Therefore, everyone can quickly create a useful lawn mower with their own hands.
You should take a 180 W motor with a special starting relay and a capacitor from the most ordinary washing machine. Even variants of the Soviet plan will do, because the extra weight in this case will play a positive role.
The asynchronous motor will the best option because it makes almost no noise. The wheels should allow the knives to be at a height from the ground (5-6 cm). Thanks to this feature, the mower is suitable for tall grass and uneven areas. It is advisable to install 4 wheels, because only then can maximum maneuverability and stability be guaranteed.
The metal sheet for the frame should be 30x50 cm wide, and as for the depth, in this regard, it is necessary to ensure that the engine and the casing covering it do not “look out” beyond its borders. In most cases, knives are made independently from steel sheets (thickness 2–3 mm and width 20–50 mm).
It is also necessary to ensure that the cutting edge is slightly turned down and protects the motor shaft from the accumulation of plants. The handle is created from a water pipe, which the operator bends as he likes.
FROM CHAINSAW FRIENDSHIP
The specified type of chainsaw has the necessary level of power, so it will be an excellent basis for a future garden assistant. To create you will need:
- the basic mechanism is the engine;
- a frame that will play the role of a support for mounting fixture nodes;
- protective casing;
- knives;
- wheels;
- parts and handles that are part of the control system.
Having taken out the engine from the good old, but already unnecessary, chainsaw, it is important to simply install it in a trolley of a mobile nature, without changing anything in the mechanism. And you can create a trolley of the specified plan using 25x25 corners with dimensions of 500 mm and 600 mm. Then they must be connected by means of a welding machine in the form of a frame.
Then wheels are installed in the area of \u200b\u200bthe corners, and a kind of chassis is obtained.
The next step is to "save" the old chainsaw from the tire and "helm". The handle is also made from a water pipe, as in the previous lesson.
The "steering wheel" should be screwed to the resulting handle, and then increase the length of the gas cable and fuel hose.
Moreover, in order for the shaft to be placed from below, you need to scroll it onto the frame using a special hole on the gearbox. It is also necessary to use the two fastening studs of the flywheel housing located at the bottom.
After installation cutting tool you can start working with a lawn mower made from a chainsaw.
Do-it-yourself lawn mower from a washing machine: diagram
Lawn mowers come in different capacities with petrol and electric motors.
Gasoline units are usually used on large areas, they produce a lot of noise, are able to process large volumes of grass, are not tied to power supply, that is, they are mobile.
In home gardens and summer cottages, electric lawn mowers are usually used, they are very convenient for a plot of up to 12 acres in size. The only drawback of such a lawn mower is the need to limit movement by the length of the cable.
The device of a lawn mower cannot be called complicated. It consists of a body, blades, motor and control lever. An engine is installed on a platform with wheels (there can be 2, 3 or 4), knives are installed under the platform, handles and a control lever are attached to the platform.
Some models of factory-made lawn mowers are equipped with a container for mowed grass, they have adjustable cutting height, they are self-propelled.
Our do-it-yourself lawn mower from what was lying around in the barn from the “it’s a pity to throw away” cycle does not have such qualities.
After it, you will have to remove the grass with a rake, you will have to carry it around the lawn yourself, using some effort, the mowing height will be the one that we set during assembly. But it may well keep our lawn in perfect condition, not inferior to expensive models.
What does it consist of
To make a lawn mower with your own hands, you will need not so many things:
- engine from an old washing machine,
- wheels from an old baby stroller or trolley,
- metal sheet 2–4 mm thick,
- tool steel knives
- thin water pipe for the handle,
- electric cable,
- fork,
- switch.
A 180 W motor, taken with a starting relay and a capacitor from a simple washing machine, is quite suitable, you can also use the Soviet model - its severity will come in handy here. It is better if the motor is asynchronous - it makes less noise.
The wheels need to be picked up (or made with your own hands from plywood and bearings) so that the knives are at a height of 5-6 cm from the ground - this will be the height of the grass mowing.
The number of wheels depends on the wishes of the owner: 4 - guarantees stability and the same height of the grass, 3 (moreover, 1 wheel is installed at the rear of the frame) - the same, but more economical, 2 - ensures mobility and maneuverability, the ability to work at different angles. A two-wheeled car is easier to manage among bushes, trees or some decorative elements installed on the lawn.
The metal sheet for the frame should be approximately 30 by 50 cm, usually the width of the frame is made at least 30-50 cm, and the depth is such that the engine and the casing covering it do not crawl out of its borders.
Knives are usually made by hand from mild steel 2-3 mm thick and 20-50 mm wide, the steel should not be brittle, a hacksaw blade for wood is well suited. The cutting edge should be slightly curved down, this will save the motor shaft from winding the grass.
The handle can be made by bending the water pipe so that it is comfortable to hold it without bending over. The handle is welded to the frame of the lawn mower, it needs to provide a place for winding the cable.

Video instruction on how to make a mower yourself using a motor from an old washing machine.
Manufacturing plan
Having picked up all the components, you can start making a lawn mower with your own hands, this can be done in one day off. If there is a ready-made chassis from a stroller or trolley, then a platform made of metal sheet must be installed and welded on it.
If this did not turn out to be the case, then first you need to weld a frame from a metal corner (preferably 25 by 25 mm in size), weld racks for wheels (2, 3 or 4) in the corners from the same corner, weld a platform to it.
From the pipes you need to make a U-shaped handle of a convenient height in accordance with growth and weld it to the platform.
After that, a hole for the motor shaft is cut out in the platform. At the front of the frame, a protective bow or mild steel grille must be welded.
The grid is even preferable, it will extinguish the energy of the knife if it suddenly breaks, protect the knife from slipping off the shaft, and fix the stems of plants for a more even mowing.
The upper and lower strips of the grille can be bolted, and a preformed wire can already be welded to them. This grid must necessarily provide a clearance for the knife of at least 1 cm in front and 2 cm below and above.
The electric motor is installed on the platform, the shaft must pass into the prepared hole. A prepared knife with sharpened cutters is installed on the motor shaft, in the middle you need to drill a hole in advance. The knife must be balanced and centered.
You can check this by turning the knife by hand - it should spin easily and without distortion.
The engine must be covered with a special casing to protect it from grass, but we must not forget that it must be cooled during operation, which means that it is desirable to make holes in the casing.
Device advantages
A do-it-yourself lawn mower has a number of advantages over a factory one. Her creation freed the barn from an old washing machine, wheels, wire, and other things lying around that were waiting in the wings.
The final cost of the lawn mower will seem ridiculous compared to those offered in stores, even with the purchased parts. Among other things, a do-it-yourself device can be repaired by the same hands if necessary.
A person who has managed to assemble such a device can always improve it, refine the design, replace spare parts.
Video "Ready-made lawn mower from a washing machine"
In this video you can see how a finished lawn mower from an old machine works.
Today, the market for electric and gasoline lawn mowers can provide a large number of different options and models. But in the case when there is no budget for a mower, but you don’t want to mow it manually, then you can make a lawn mower with your own hands at home from improvised parts and materials. A do-it-yourself lawn mower will significantly save money, unlike factory counterparts.
Necessary materials and tools
A device such as a do-it-yourself electric mower is not a basic necessity. But the presence of such a tool at home will significantly save labor costs when mowing grass. Very simple lawn mowers can even be made from an electric motor. They include the same parts and functionality as the factory counterparts.
Electric lawn mowers include:
It is necessary to constantly observe the safety of work, and therefore it is necessary to install an element of emergency and automatic shutdown electric mowers.
All electric mowers work in the same way. After applying voltage to the electric motor, its shaft begins to rotate. And since the knives are fixed on the shaft, they cut the grass at high speeds of the electric motor.
Selecting the right engine
As a motor for a lawn mower, you can use the engine:
- from a vacuum cleaner;
- from the washing machine;
- from Bulgarian;
- from the trimmer.
If you need to mow small areas, then just right there will be an engine from an old drill. It does not even need to be disassembled, just fix it in a vertical position.
A do-it-yourself lawn mower from a washing machine or a Soviet-style vacuum cleaner can be made without much effort. They have all the necessary details. The best option for mowing grass near the house is an electric motor with a power of 0.5 kilowatts, and the recommended speed is about three thousand. The quality of work and grass mowing depend on the speed of the motor, and accordingly its blades.
The longer the knives of the device, the lower the number of revolutions it can be used due to the increase in linear speed. But its power must increase in order to deal with the increasing load. In practice, it has been proven that for domestic needs a device with a power of one kilowatt and an engine speed of one and a half thousand is enough. Moreover, the working plane is half a meter. In the event that the engine power is less than these indicators, then the blades need to be sharpened regularly to obtain the desired result.
If only a three-phase motor was found on the farm, then starting capacitors must be added to this design. They must match the capacity of the engine. Drawings of a lawn mower from a grinder or other source materials can be easily found on the Internet or specialized literature.
Additional materials for construction
Blades are intended for direct cutting of grass. In order to make them with your own hands, you need to prepare steel plates up to 45 centimeters long, 3-4 centimeters wide, and 2-3 millimeters thick. Thin blades cut grass better and better, while thick blades are more durable.
They can be made in three variations:
- One strip, which has holes exactly in the center, and sharpened edges with the right parties. Its length should be from thirty to fifty centimeters.
- The structure, consisting of two parts, which are mounted on a solid rib, is fixed with bolts.
- Sharpened disk.
To save money, wheels and material for handles can be taken from an old baby stroller. When choosing the diameter of the wheels, it must be borne in mind that the distance between the ground and the blade should be no more than 5 centimeters. If possible, you need to adjust the height of the lawn mower. When the cutting part of the apparatus consists of two elements, then the indicators of maneuverability improve, and if from 3-4, then reliability. Such wheels can also be made of plywood and mounted on a shaft with bearings.
The blade guard can be made from plywood, a steel barrel, or the body of an old washing machine. Moreover, in such an element of a lawn mower, you need to make holes for normal functioning electric motor and air entering the closed part of the lawn mower.
The body of the washing machine can also be used to create a shroud around the blades. The spars for the motor are made of plywood or steel sheet. The cord for connecting the device to the network must be selected taking into account the power of the motor. Alternatively, you can take it from old devices.
In order to make a lawn mower knife with your own hands, as well as all other structural elements, you need to prepare the required materials in advance:
As an alternative to a grinder or a jigsaw, you can use a hacksaw for metal or wood, but with small teeth. And also, experts always recommend making a drawing of the manufactured apparatus in order to have an idea about the future design.
The principles of operation of the electric motor
Such a motor can be either single-phase, which runs on a conventional network, and three-phase, in need of additional electricity. When connecting an electric motor, you must always remember about personal safety. For a single-phase motor, RCD protection must be installed, and a three-phase motor must have appropriate capacitors.
For a home lawn mower, you can also use a drill with a speed of up to three thousand. When assembling the structure, it is necessary to choose the right power of the mower for its swath. A cordless or electric drill mounted on a base or platform will perform its tasks with high quality, and the grass will be mowed.
In the process of work, do not forget about the intervals of work, because you need to give the motor time to rest in order to avoid overheating. Such a tool will easily clear the area of grass and give the lawn an attractive look. The platform on which the engine is mounted must be of optimal size so that you can mow the grass near the wall.
Step by step assembly instructions
Depending on the starting materials for the electric lawn mower, these steps will differ. One of the most common options is to assemble a mower from an old washing machine. It will be useful to consider step by step instructions specifically for the creation of such a device.
Actions should take place in the following sequence:
For this you need:
- install the switch and switch in a convenient place near the handle of the device;
- connect the power cable with a plug;
- RCD installation.
The grass collection container must be installed at the very end. It is made in the form of a box or a bag.
Covering the knives with a sheath is a must, as this will increase safety during operation. Such protection must also be done for the motor in order to avoid the ingress of debris and its durability, as well as durability.
Bulgarian construction
There are quite a few ways to create such a device. The simplest is its bolting to a pre-prepared platform or base.
The most common option is to assemble such a homemade product using a baby carriage.
For this you need:
- Disassemble the stroller, but leave the base with the wheels.
- Prepare a board that will lie on the axles of the wheels.
- Fix it.
- Attach the grinder to the board with ties or clamps.
- On the grinder you need to install blades or fishing line.
- Attach the switch to the handle.
This design can be equipped with a protective cover so that the grass does not scatter to the sides, or with a waste collection container.
Self-taught masters throughout history have already come up with a lot of models of home-made cars. They differ in the form of assembly and the complexity of the design. More advanced models have the function of adjusting the mowing height, etc. You need to make a mower with your own hands so that safety is paramount. The button for turning on the mechanism must be set in such a way that the device turns off immediately after it is released.
In order to learn how to make a mower with your own hands, sometimes you need a good ingenuity. At the scrap metal collection points, you can always find a discarded frame from the corners. Less often, but still, you can find wheels on a hinge, preferably at an angle of 180 degrees. But even if it was not possible to find such a frame, it can be easily welded from improvised materials.
The working shaft moves due to the belt drive from the saw itself to the pulleys, on which the fishing line is attached. This design will serve for many years without the need for additional maintenance. This option is more difficult to manufacture, as it has a two-wheeled frame and two rotary cutters. On the other hand, it also has its advantages, since its performance is much higher than that of conventional self-propelled vehicles.
Self-made apparatus and ingenuity, of course, a reason to be proud of your invention. But one must also remember that collective design decisions will always be better reflected in the quality and safety of the structure.
The advantages of homemade devices include:
- saving money on purchasing the right materials at a low price instead of a new tool;
- use of a tool that does not have a presentation, but has not lost its functionality;
- self-assembly allows you to always improve the invention, as well as to know its design perfectly.
In this model, the height is not adjustable, and due to this, the lawn is not always possible to cut evenly. And also a minus is the lack of a container for collecting grass, which automatically increases the labor costs of a person. A heavy self-assembly tool can sometimes ruin the lawn with its weight. This is an objective factor in favor of choosing a factory model instead of self-assembly.
A lawn mower with a washing machine engine sounds more than strange at first glance. But if you think about it carefully, there is nothing strange in this. A lawn mower is inherently a fairly simple device, which, however, is fabulously expensive in the store. Yes, it's not even about money, but in principle. If you are a seasoned do-it-yourselfer or want to become one, then why pay someone for a ready-made lawn mower when you can do it yourself, especially since the garage is full of the necessary spare parts.
About the functionality of homemade
Some will say: “fu, a homemade lawn mower, because it is not safe, and it will be less useful than a branded product”! In fact, these statements are nothing more than the prejudices of loafers who are once again afraid to take a screwdriver with pliers in their hands, let alone a more or less serious tool. If you do everything right, a homemade lawn mower will be no worse, and in some ways even better than factory models - for the price, that's for sure.
The power of the lawn mower will be enough to mow the grass without any problems, and the body can be made very compact, so that henceforth such a do-it-yourself unit would be easier to store. Operational safety issues can also be called into question, because even when using a factory lawn mower, you can suffer. Here much depends not on the device, but on the person who uses such a device.
A homemade lawn mower, the design of which we will offer in this publication, is no more dangerous than equipment from the world's leading companies.
Required parts and tools
So, if you are determined to make your first lawn mower with your own hands, you need to remember that you first need to collect the necessary parts and tools, and only then make your plans. Let's talk about materials first.
- Collector motor from an old washing machine. This is the main part of the lawn mower. Experts advise taking the engine as powerful as possible. Better not even from a washing machine, but from a Soviet-style centrifuge.
If you don’t have a powerful engine, it doesn’t matter, the lawn mower will still turn out to be quite functional.
In addition to the main parts, you will need a certain number of fasteners: studs, bolts, nuts, washers, well, however, everything is as usual. Now let's say a few words about the necessary set of tools.
- Various open-end and socket wrenches.
- Electric welding.
- Drill.
- Measuring tools.
- Multimeter.
- Bulgarian.
- Marker.
- A hammer.
- Pliers.
- Screwdrivers.
- Soldering iron.
Working process
Well then, let's get started. If, in the process of making a lawn mower with your own hands, you realize that some parts are missing or it is better to take others instead of some parts, it does not matter, this is normal. After all, when you make something with your own hands, you get involved in the creative process and you don’t notice how you improve the original project. The same will happen in your case. But let's not "deep into philosophy", but let's get down to business.
The first thing we will do with our own hands is to make the chassis of the trolley, to which we need to attach the wheels. The chassis should be low from the ground, because we are making a lawn mower, not a yard waste cart.
Cut out in the center of the platform round hole, such that the motor shaft passes into it and some clearance remains. We put the engine with the shaft down so that the shaft goes into the prepared hole. We outline a place on the platform for the engine frame.
When the engine is installed on the platform, it is easier to mark a place for its frame.
We fold the frame from the corners and weld them to each other. In order for the engine to “sit” securely in this frame, you can additionally fasten it with a special clamp - you do not need to weld the engine housing to the frame. Next, install the lawn mower handle. It can be welded, but it is better to fix it on the corners with bolts so that the lawn mower can then be disassembled if the need arises.
Now we need to connect the engine. In this case, it is better to install the starting capacitor and other electrics in a special plastic box. If the box is not at hand, you can take the usual plastic bottle. Such a bottle can be fixed at the engine itself, but it is better to place the switch on the handle of the mower, for greater convenience.
Now we fix a suitable bushing on the motor shaft, put a knife or cutting disc on it and fix it. In this case, it is important that the knife is located at the right height and is securely fastened. In order for the knife to be put on the sleeve, you may have to drill a hole in it - see for yourself. Everything, the electric lawn mower is ready, now it remains to connect it to the network and arrange the first mowing of your lawn.
Security measures
When using a homemade lawn mower, be careful. Do not turn on the appliance when it is raining or when the grass is still wet. Factory lawn mowers have everything electric wires are reliably isolated, and the engine is enclosed in a waterproof casing. In our case, if we decide to mow the grass in the rain or after it - defeat electric shock can't be avoided.
Do not pass the lawn mower to children, and do not use it near playing children and pets. Before mowing the lawn, make sure that foreign objects do not lie in the grass: children's toys, stones, garden hoses, etc. If the blade gets stuck while working, do not reach for it until the power is off from the mower. Be reasonable and everything will be fine!
The emerald lawn is an excellent decoration for a suburban area, but without care it quickly turns into impenetrable thickets.
A lawn mower is required and if an old household appliance with a motor is available, the device can be assembled by yourself. Next, we will tell you how to make a do-it-yourself lawn mower from a washing machine.
A lawn mower, due to various options, can have a complex device, but basically it is just an engine with a knife put on its shaft, mounted on a chassis with a handle. It happens that the shaft with a knife is installed separately and connected to the engine shaft by a chain or belt drive.
Two types of engines are used:
- Petrol: a lawn mower with such a drive is autonomous, which is very convenient for a large lawn area.
- Electric: you need to connect to the mains with a wire, so you won’t go far on such a device.
A lawn mower equipped with an electric drive has a number of advantages:
- works silently;
- no exhaust;
- no need to store fuel and waste time refueling.
An electric mower is the preferred option for lawns up to 12 acres.
The platform on which all nodes are installed is called the mowing shield. From below, it has sides that do not allow the grass to scatter in all directions.
According to the number of wheels, lawn mowers are divided into:
- Two-wheeled: the inherent maneuverability of this device allows you to process hard-to-reach areas. But it's difficult to get the knife level, so it takes experience to make a clean cut.
- Tricycles: it is more difficult to maneuver, but the mower is stable and its knife occupies a strictly horizontal position.
- Four-wheeled: irrational option: the advantages are the same as those of a 3-wheeler, but you will have to spend more on one wheel.
Do-it-yourself lawn mower to the country
The dimensions of the wheels and other elements are selected so that the knife is located 5 - 6 cm above the ground - then the cut will be even.
To control the lawn mower, a handle is attached to the chassis.
Unlike a purchased one, a home-made mower cannot be made self-propelled and equipped with mechanisms for collecting grass and adjusting the cutting height. But she will successfully cope with the main function.
Necessary tools and materials
The arsenal is:
- welding machine with electrodes;
- drill with drills for metal;
- soldering iron;
- spanners;
- screwdriver;
- roulette, ruler;
- core and scriber;
- marker or pencil.
Also need materials:
- Blank for mowing shield: in a homemade version, this element is made from a large frying pan, a shallow bowl, or the bottom cut off from a large saucepan. In the absence of such, a steel sheet with a thickness of 2 - 4 mm is used.
- Chassis or wheels: the mowing shield is fixed on the finished chassis from a wheelbarrow or baby carriage, and if they are not there, axles are welded to it and wheels are put on them. They are borrowed from the same wheelbarrows or strollers, or they are made independently from plywood or plastic.
- Mounting hardware: bolts with nuts, studs, screws.
- Copper 3-core wire with plug.
You will also need a steel equal-shelf corner with an arbitrary shelf width.
Process of creation
start by removing the electric motor from the washing machine.
Preferred engines:
- powerful;
- heavy (provide stability);
- asynchronous type (do not make noise).
These requirements are most satisfied by motors from Soviet-made washing machines, and even better - from centrifuges.
If the engine is low-power, the shortest knife is installed: the long one will cut the grass evenly only if it is constantly undermined.
cutting part
A homemade mower can be equipped with a purchased knife - this will not greatly affect costs. If it is decided to do this element with your own hands, consider the following:
- Geometric parameters of the knife: length: 30 - 50 cm, width: 2 - 3 cm and thickness: 2 - 3 mm. The longer the knife, the more productive the mower will be, which is important for large areas. But we must not forget about the power: the knife of the maximum length works properly only with engines with a power of 1.5 kW or more.
- The hole must be drilled exactly in the center so that the knife is balanced. At high speeds, imbalance will cause vibration with subsequent destruction of the shaft and motor.
- In the center of the knife, a short tin cylinder is attached coaxially with the hole, a suitable blank is a tin can. Without such a casing, the grass will be wound on the shaft.
- The cutting edge is turned at an angle of 60 degrees, with a smaller angle it will quickly become dull.
- The edges without cutting edges, that is, the back side of each half of the knife, are folded in order to ensure that the grass is cleared from the mowing shield with the help of blowing.
There are two knife options:
- Full strip: made entirely from a strip of tool steel. For processing, it must be softened by tempering: the workpiece is heated in an oven and then allowed to cool slowly along with the oven. After processing, the part is hardened and then the cutting edges are sharpened.
- Composite: only the end parts of the knife 5 cm long, that is, its working part, are made of tool steel. The middle part, that is, the base, is made of ordinary inexpensive steel. All components are bolted together.
The second option is more difficult to implement, but has advantages:
- costs less;
- when hitting a stone, one bolt is sheared and the cutting part is bent, while a full-blade knife in such a situation can damage the shaft and motor.
Equipped with lawn mowers and knives in the form of a disk. When meeting with a stone, they do not break, but only become dull.
Pen
As such, you can use one of the following elements:
- stroller handle;
- plastic water pipe;
- a cutting from an agricultural tool.
From these elements, a U-shaped structure is assembled.
The optimal length for a user with an average height is 90 cm.
A rubber hose is put on a metal handle in the grip area for the purpose of electrical insulation. At the top, in close proximity to the user's hands, an emergency button is attached for an emergency stop of the motor.
Electrician
To start the engine, it is best to use the "native" control system from the washing machine.
In its absence, for asynchronous motors, the same starting scheme is used as for conventional single-phase motors: with the help of a starting capacitor, the windings are connected to each other.
The capacitor and other components of the electrical circuit should preferably be placed in a plastic box, where they will be protected from dust and pieces of grass.
A regular plastic bottle can serve as a blank for such a box.
Assembly process
When making a homemade lawn mower, proceed in the following order:
- A mowing shield is attached to the chassis. If it was not possible to get the finished chassis, they act differently: axles are welded to the mowing shield and wheels with bearings installed in them are pressed onto them.
- A hole is cut in the mowing shield with a diameter several millimeters larger than the diameter of the electric motor shaft.
- An electric motor is placed on the shield, passing its shaft into the hole just made. Having thus determined its correct position, it will be possible to select the optimal dimensions of the support frame.
- Using electric welding, a frame for an electric motor is made from a corner. In its design, it is possible to provide a place for a plastic box for electrical parts.
- The engine is screwed to the frame, a knife is fixed on the shaft.
- Next, a tin casing is screwed to the frame to protect the motor from dust. A lot of holes are drilled in the casing for ventilation.
- A handle made in the form of the letter "P" is attached to the mowing shield or chassis.
- In the front part, a protective grille or arc is welded or bolted. The grid has more advantages: it holds the grass, ensuring an even cut, prevents the knife from slipping off the shaft and holds it in case of a break.
- A bolt is welded to the mowing shield to connect the ground wire.
- A wire is connected to the terminals of the starting device, and its third core in yellow-green insulation (grounding) is connected to the bolt on the mowing shield.
The lawn mower is ready, you can start testing.
Safety
The probability of an accident for a homemade lawn mower is higher than for a branded one, so it is recommended to follow these rules:
- Do not mow a wet lawn and do not leave the device outside when it rains. It is not protected against moisture, so a short circuit and electric shock are likely.
- There must be no children and animals within a radius of 30 m from the working mower: a stone or a detached knife may fly out from under the device.
- The user should wear long trousers and closed shoes.
- In the event of a knife jamming or other breakdown, repairs can only be carried out after the device has been de-energized.
- Do not leave the mower without turning it off.
Check your lawn for rocks, toys, and other items before mowing.
