How To Make A Lawn Mower

How to choose a lawn mower. Types of lawn mowers

There are three types of lawn mowers:

  • Wheeled mowers that drive on grass. They are electric and gasoline.
  • Devices that are worn during mowing are trimmers. They are equipped with a petrol or electric engine.
  • Riders. Lawn mowers that “carry” us during the mowing process, or on which we ride on the lawns.

Electric lawn mowers: sensitivity to the details of the device is the key to their efficient and long service.

How to choose an electric lawn mower

And we will talk about the first type of lawn mowers. Electric wheeled, although much of what will be discussed later in this material will be true for gasoline devices. Compared to gasoline-powered machines, electric lawn mowers make less noise during operation. In addition, do not forget about environmental issues: go out of town to breathe in the exhaust again? No, thank you!

When purchasing an electric lawn mower, there are some nuances to consider:

  • The density and composition of the grass you are going to cut;
  • The shape and size of the “experimental” area;
  • Topography.

Having decided on the nuances, you will know exactly what details you need to pay special attention to when choosing an electrical device.

The main thing in organizing lawn mowing is regularity: the grass must not be allowed to grow up to the waist, otherwise we will lose its original softness. After mowing, rare and tough stems will remain, through which the earth shines through. It will take time to evenly overgrow with grass.

It is important not to “miss” the grass in the spring. Somewhere in early May (let’s take Victory Day as the mark) the grass is just growing. But it would be better to make her first mowing, otherwise she will make a magic jump in her height. In one week, the greens will grow up to your knees, and in the spring the sod is very dense, the grass is fresh and juicy, saturated with spring waters. As a result of this, you will mow for a very long time and painfully.

And an electric wheeled lawnmower cannot “take” grass up to its waist, unless you remove the grass collection box and raise the mower on its hind legs. But this will be quite an extreme option, and excessively laborious: to transport a reared lawn mower, you need extraordinary strength. If you miss the moment, then it is better to take a scythe and, like our ancestors, forward, through the dew with a song.

A lawn mower is designed for mowing lawns, but don’t worry if you haven’t purposefully planted the grass. You can give your site a beautiful look by mowing down the natural flora, whether it be even dimples or nettles. If this is done regularly, the mown area will be attractive: the weeds will disappear and the ground will be covered with mowing-resistant grasses. Bluegrass, clover and others, depending on the soil composition on the site.

The advantage of natural turf:

  • It does not require maintenance, since the composition of the grass is independently regulated,
  • The lawn adapts to climatic conditions.

How to make a lawn mower with a cordless angle grinder

Materials and tools used by the author:

List of materials:
– a small freon cylinder or similar;
– Sheet steel;
– axles and wheels;
– a piece of a round pipe;
– good steel plate for knife.

Lawn mower manufacturing process:

Step one. Manufacturing of the case
First of all, we will make a case for a lawn mower, for this we need one of the sides of the gas cylinder. Make sure that the cylinder contains non-flammable gas before work, otherwise it will explode during cutting.

We cut off the upper or lower part from the cylinder, then the author slightly bent the edge of the cylinder on his pipe bending machine.

Install part of the balloon on the bicycle wheel and rotate it so you can find the center. Next, the author draws a circle and cuts out the convex part of the balloon. Instead of this convex part, we weld an even piece of sheet steel, that’s all, now we have an excellent basis for installing an angle grinder and other equipment.

Step two. Clamp
Now we will make a clamp with which we will attach the angle grinder to the lawn mower. The author carved it from thick sheet steel, but everything can be done from a piece of round pipe. The angle grinder is clamped with a clamp in the part where the guard is installed.
Of course, for more reliability, so that the angle grinder does not crank, it would be nice to attach it with an additional clamp.

Choosing the right engine

The following engine can be used as a motor for a lawn mower:

  • From a vacuum cleaner;
  • From the washing machine;
  • From an angle grinder;
  • From trimmer.

If you need to mow small areas, then the engine from an old drill will be just right. It does not even need to be disassembled, it is enough just to fix it in an upright 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. An electric motor with a power of 0.5 kilowatts is considered the best option for mowing grass near a house, and the recommended number of revolutions is about three thousand. The quality of work and mowing depends on the speed of the motor, and accordingly its blades.

The longer the blades of the device, the lower the number of revolutions it can be used due to the increase in the linear speed. But its power must be increased in order to cope with the increasing load. In practice, it has been proven that a device with a capacity of one kilowatt and an engine speed of one and a half thousand is sufficient for household needs. over, the working plane is half a meter. In the event that the engine power is less than these indicators, then regularly you need to sharpen the blades to obtain the desired result.

If the farm only found a three-phase motor, then starting capacitors must be added to this design. They must match the capacity of the engine. Drawings of a lawn mower from an angle grinder or other raw materials can be easily found on the Internet or specialized literature.

Step-by-step assembly instructions

These steps will vary depending on the starting materials for your electric lawnmower. One of the most common options is to assemble the mower from an old washing machine. It will be useful to consider step-by-step instructions for creating such a device.

How To Make A Lawn Mower

Actions should take place in the following sequence:

  1. Manufacturing a frame or spars for a future engine design. You need to make it from a metal or steel sheet 500 by 500 millimeters.
  2. In the central part of the sheet, a hole should be drilled for the shaft of the electric motor.
  3. From the bottom of the metal sheet (spars) corners are welded along the perimeter. And also they can be bolted.
  4. Then you need to install the wheels. They can be made yourself from plywood or wood, or removed from old appliances. They are placed on the shaft (metal axis).
  5. After that, the motor must be fixed to the platform. To do this, it should either be welded on pre-installed metal corners, or drilled holes for the existing holes in the motor itself, and then bolted.
  6. Next, you need to install a handle to control the structure.
  7. A protective cover is mounted under the platform for control.
  8. A metal knife is installed (homemade or ready-made). It is attached to the motor shaft.
  9. To protect the motor from grass it is necessary to mount a tin can on its shaft.

All mechanical parts are assembled. Next, you need to start the electrical diagram of the structure.

This requires:

  • Install the on / off switch in a convenient place near the handle of the device;
  • Connect the power cable with a plug;
  • RCD installation.

Covering the knives with a sheath is mandatory as this will increase safety during operation. Such protection must be done for the motor in order to avoid debris and its durability, as well as resistance.

Required materials and tools

A device such as a do-it-yourself electric mower is not a daily 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 details and functionality as factory counterparts.

Electric lawn mowers include:

  • An electric motor or drive mechanism with which the blade attachments rotate;
  • The base 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 for switching the mechanism on and off;
  • Power cord;
  • Container for collecting grass or removing it.

All electric mowers have the same operating principle. After applying voltage to the electric motor, its shaft starts to rotate. And since the knives are fixed on the shaft, they cut the grass at high speeds of the electric motor.

How to make a DIY lawn mower

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 the mower, and you don’t want to mow by hand, you can make a do-it-yourself lawn mower at home from improvised parts and materials. A do-it-yourself lawn mower will significantly save money, unlike factory counterparts.

The principles of the electric motor

Such a motor can be either single-phase, which operates from a conventional network, and three-phase, which requires additional electricity. When connecting an electric motor, you must always remember about personal safety. For a motor operating on one phase, an 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 correctly select the power of the mower for its swath. A cordless or electric drill mounted on a base or platform will perform its tasks efficiently, and the grass will be cut.

In the process of operation, do not forget about the operating intervals, as you need to give the motor time to rest 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 installed must be of the optimal size so that you can mow the grass near the wall.

Additional materials for construction

Knives are designed for direct cutting of grass. In order to make them yourself, you need to prepare steel plates up to 45 centimeters long, 3-4 centimeters wide, and 2-3 millimeters thick. Thin knives cut grass better and better, and thicker ones are more durable.

They can be made in three variations:

  1. One strip, which has holes exactly in the center, and sharpened edges on the right sides. Its length should be from thirty to fifty centimeters.
  2. Two-piece structure that is fixed on a solid rib, fixed with bolts.
  3. Sharpened disc.

To save money, the wheels and handle material can be taken from an old 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, adjust the mower’s seating height. When the cutting part of the device consists of two elements, then the indicators of maneuverability are improved, 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. over, in such an element of the lawn mower, holes must be made for the normal functioning of the electric motor and the entry of air into 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 motor side members are made of plywood or sheet steel. 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 do-it-yourself lawn mower knife, as well as all other structural elements, you need to prepare the required materials in advance:

  • Electric drill;
  • A hammer;
  • Angle grinder with disc;
  • Jigsaw with a set of files;
  • Pencil;
  • Roulette;
  • Pliers;
  • Vice;
  • Sandpaper;
  • Screwdriver;
  • Welding;
  • Wires;
  • On and off button;
  • A set of bolts and nuts;
  • Corners;
  • Wooden blocks.

From a chainsaw

Can be converted into a chainsaw mower. We take the motor to be put on the cart. It is made according to the type of frame from the profile corners of 2.5 by 2.5 centimeters. Its dimensions will be approximately 50 by 60 centimeters. Wheels are installed at the corners. You should also install the steering wheel and tire there.

A handle is made of the pipe, the height of which can be adjusted. A steering wheel, hose and cable are attached to it. The engine is now screwed onto the frame. The tire is secured using a hole in the gearbox. The casing fasteners are placed below. This is the future foundation of the mower. Now it remains to install the knives using welding. This is carried out on the saw star on a pre-installed pipe length.


To make a lawn mower for grass, you need to have a specific list of parts on hand. The main engine will be from any device that is not used for some reason. The motors from small devices are unlikely to withstand the heavy loads that are inevitable when mowing grass. They overheat and break down too quickly. And there is no point in repairing them. They often try to use motors from vacuum cleaners, but they definitely will not cope with such work.

The next element that will be needed is a knife. It must be made of strong and thickest steel. There may be several of them. A self-sharpening disc may also work. This is the simplest and most durable option.

If we talk about a handle for a lawn mower, then it can be taken from an unnecessary wheelbarrow or an old stroller. Besides, we need a metal frame on which all elements of the device will be attached. It is important that there are no traces of corrosion on it, and that all parts are intact and not damaged.

Also, to create a lawn mower, you will need a power cord, preferably longer. But this is in case we are interested in an electric home-made mower. You will also need wheels with a small diameter. For the unimpeded movement of the self-propelled mower on the site, wheels with a radius of at least 10 centimeters will be enough.

You will also need a special protective cover that is fixed around the cutters. It can be made from sheet metal or you can choose a suitable ready-made solution in size. You will also need a protective cover to ensure the safety of the person operating the mower. In addition, it will keep the cutters from stones. Other parts may be added to the mower, depending on the required design features. For example, a grass catcher will allow you not to leave grass on the territory, but to collect it in a special container. He can be:

  • Combined;
  • Tissue;
  • Plastic.

Fabric solutions are very compact and lightweight, but require washing from time to time. When the cells begin to clog at the mesh, a kind of airlock is created, which may be the cause of motor overheating.

Plastic counterparts are made using high quality materials. If a foreign object accidentally falls into them, this will not disrupt the operation of the device in any way. The plastic container is easy to clean.

Combined solutions usually come with expensive models of lawn mowers, because of what they have the advantages of both categories of containers.

From an old vacuum cleaner

Another option for creating a lawn mower is to transform a vacuum cleaner. First you need to make a cutter. If possible, a polymer type thread should be used. It needs to be attached to a steel segment, in the middle of which there is a hole. Now a knife is made from a saw. By the way, if the steel is very hard, then it should be softened.

Now the workpiece should be very hot, and then let it cool. When the knife is made, it needs to be heated again and cooled very quickly. The torch should be up to half a meter long. The cutting section is usually sharpened at a 60 degree angle. The edges are made along the knife edges. The gross opening must be as accurate as possible, as the cutters have to be balanced in the future.

All parts of the structure must be fixed as high quality as possible. So that the cutter does not accidentally deform after hitting the stones, it must be assembled. Steel knives should be attached to the center in the center from 2 sides with bolts. Upon impact, the knife will only turn and the risk of damage will be minimal.

A hole is made in the plate so that there is an opportunity to put the motor. It is placed in a slot and clamped with a steel strip, then set across the slot and screwed in with screws. The part where the turbine is located is removed from the motor. The cutting element is installed there.

On the reverse side, the turbine is dismantled, and a tin fan is installed instead. To protect the motor, a tin cover is attached to the plate. You can use the cover from the vacuum cleaner from which the engine was removed. A PCB plate with a motor is installed on a chassis with wheels. At the final stage, the handle should be attached to the device using the brackets on which the switch is fixed. Now the cables are connected to the motor and the button. At the end, they must be insulated and the system operability checked.


So, before you start assembling the lawn mower, you need have the following items on hand:

  • Materials for the frame;
  • Wheels;
  • Pens;
  • Protective cover;
  • Engine;
  • Frame where all the parts will be attached;
  • Knives;
  • Control elements. RCD, switch, cable with a plug for connecting to a socket.

Besides, an important preparatory step will be the creation of drawings and diagrams of the future design. This will help to maintain the correct location of all elements of the future structure and create the correct frame that can withstand the weight of all elements and will look beautiful from an aesthetic point of view.

How to make a DIY lawn mower?

  1. Device
  2. Training
  3. Mower creation process
    • From the washing machine
    • Of angle grinder
    • From an old vacuum cleaner
    • From a drill
    • From a chainsaw
    • Security measures

    Mowing grass on a suburban area allows you to give the territory a well-groomed and pleasant look. But constantly doing this with a hand scythe is very inconvenient, not to mention a serious loss of time and effort. But it is not always possible to purchase a lawn mower. Then you can do it yourself. Let’s try to understand the intricacies and features of this process.

    From the washing machine

    To create a lawn mower from an old washing machine, will be required:

    • Engine from her;
    • Steel knives;
    • Wheels;
    • Pipe that will become the basis for the handle;
    • Electric drive;
    • Fork;
    • Switch.

    If the mower will be made from a motor from a machine, then it is better to take a 170-190 W model equipped with a starting relay with a capacitor. You also need to pick up wheels.

    The knives should be made of steel that is 2 or 3 mm thick and half a meter long. The cutting part bends down a little, which helps to protect the shaft from various objects falling into it. The handle is created from a tube so that the device is comfortable to hold. It is attached to the frame by welding.

    A platform is mounted on the chassis from the trolley, previously made of sheet. Then a hole is made for the motor shaft. A steel grill is installed on the front as protection. The upper and lower parts of it are screwed with bolts, to which the wire is attached.

    The grill of the device allows you to create a gap for the knife. The motor is attached with the shaft through the hole. A previously sharpened knife is mounted on it, and a hole is made in the middle.

    The knife should be balanced and centered. The motor is covered with a shroud for protection. Considering that it needs to cool when it is running, there should also be holes in the casing. It is connected to the wiring, which is fixed to the body. The metal handle should be wrapped with a rubber cover in order to protect against possible electric shock.

    How to make a DIY lawn mower knife?

    Perhaps the best option for caring for your own land is a lawn mower. With this device, you can level the grass level and refine the area with minimal effort. The main disadvantage of lawn mowers is that the knives wear out the fastest during operation. Chips and notches appear on them, and periodic sharpening of the edge as a result significantly reduces the width of the knife.

    The easiest way out of the situation is to purchase a new branded knife. Nevertheless, if the farm has the necessary material and tools, it is quite possible to assemble it yourself.

    Required materials and tools

    To make a do-it-yourself lawn mower knife, you need a minimum set of tools:

    • Angle Grinder;
    • Vice;
    • Electric drill;
    • Grinding stone 400. 600 grit.
    • Ruler or tape measure.

    Of the materials, you only need a piece of steel sheet with a thickness of at least 3 mm. It is important that the metal is resistant to breakage. It is important to understand that a broken blade at high engine speeds can seriously damage the mower.

    How to do it yourself

    The lawn trimmer blades are available as one continuous long strip or two shorter blades. The easiest way is to make one long blade. The point is that it is very difficult to balance two separate cutting elements that work synchronously at high speeds. The accuracy of the balance of the blade determines the uniformity of its operation, vibration, and this also affects the resource of the device and the convenience of its use.

    The blade is pretty simple to make. First of all, you need to take a sheet of steel with a thickness of at least 3 mm and cut out the blade of the future cutting element with an angle grinder. The dimensions of the plate are approximately as follows: the width is from 40 to 60 mm, and the length can be in the range of 30 to 50 cm.The length of the canvas depends on the diameter of the protective dome.

    See also  How to Make a Lawn Mower at Home

    After the blade has been cut, you need to make the edge of the blade, as well as the blade of the knife. They are needed to create a swirl in the mowing process. The length of the blade is 50 mm along the blade and 25 mm across. Bending height approx. 15 mm. The cutting edge itself should be 60. 80 mm long. It is stitched from the edge of the canvas.

    Strictly in the center of a homemade garden trimmer knife, a mounting hole is made. Ideally, if done correctly, the canvas will already be balanced. This can be checked by putting it on a horizontal rod and seeing how smoothly the knife is held in a horizontal position. It is possible that the plate will deviate in some direction. Then you need to grind off a part of the heavier edge a little, but this must be done very carefully so as not to overdo it.

    Usually you won’t need to do this if the mounting hole is centered, but you must re-check the balance. A poorly balanced blade during operation causes beating and has a detrimental effect on the resource of the lawn mower.

    Making homemade single-sided knives is not recommended. They are quite difficult to balance, and during operation, the position of one element relative to the other can get lost. This will cause an imbalance and negatively affect the convenience of mowing and the technical condition of the device.

    DIY lawn mower repair: the main causes of problems and their elimination

    Owners of beautiful and green lawns using lawn mowers can face problems while working. In this article we will tell you, how to repair gasoline lawn mowers with your own hands, and you will also find out the common causes of breakdowns of this device.

    • Features of the structure of lawn mowers
    • The main causes of lawn mower problems
    • Rattling and rumbling during operation
    • Intense vibration during operation
    • Whistling while cutting grass
    • Lawn mower leaves grass behind
    • Mower runs intermittently or does not start at all

  5. Features of the structure of lawn mowers

    Most mowers are push-driven from the rear, but there are models that can be controlled using the steering wheel. A certain type of device is designed for different jobs. Small ones handle a normal medium-sized area, while large steering mowers use large lawns.

    But all devices have the same structure. Let’s start with the case. Gasoline mowers have aluminum and steel housings.

    Electric lawn mowers lighter than gasoline ones and their body is made of ABS plastic. It is used to create car bumpers. The mower wheels should be large in diameter, so they can easily overcome bumps. They also create less pressure on the ground and do not injure the lawn. Bearings provide high reliability and durability.

    Many manufacturers make the two front wheels swivel. This allows for increased maneuverability. The front wheels swivel around an axle so you don’t have to raise the mower to change direction. Let’s talk about knives. All of them are usually rotary and located on the working shaft. The diameter of the knives determines the width of the lawn mower.

    The rotor performs following functions:

    • Support of knives at a certain distance from the ground;
    • Rotates quickly and cuts grass;
    • Has blades serving as a fan. The air flow from the fan carries the cut grass into the grass catcher.

    All knives are made of high quality steel.

    Grass collector Is a large bag or plastic box with air holes. It can be easily removed and the contents discarded. Many mowers not only cut the grass, but can also grind it into flour. This process is called mulching. In this case, do not use a grass catcher, since the greens after mowing will serve as fertilizer.

    Repairing lawn mowers if the engine won’t start

    It happens that, despite the presence and normal supply of fuel, the engine does not start. Most often, the absence of signs of life indicates a failure of the ignition coil. If, upon visual inspection, all electrical circuits are in order, then this coil will need to be replaced.

    DIY lawn mower engine repair

    Less common case. Bad carbon or spark plug failure. It is determined by visual inspection of an unscrewed candle. The most efficient way to identify this problem. Replace the candle with another, obviously working. When thinking about how to make a lawn mower if the engine does not start, pay attention to replacing the spark plugs with new ones, and preferably more reliable.

    Sea buckthorn (lat.Hippophae)

    Photophilous plant, prefers open, but not windswept places. It should be planted at a distance of 2.5. 3m from each other. For plants to be effectively pollinated, there should be one “male” for 5-10 “female” trees.

    Lawn mower. A wonderful alternative to a manual scythe, making it easier and faster to cut grass in a wide variety of places, including those where a regular scythe simply will not turn. But behind comfort and convenience lies a sophisticated modern mechanism that requires tireless attention and regular maintenance.

    Regardless of the manufacturer, all units have a similar design. Therefore, do-it-yourself Viking lawn mower repairs are performed in the same way as repairs of other brands: Husqvarna, Shtil, Bosch, Gardena, Oleo Mak. A homemade lawn mower will not be an exception, but eliminating a breakdown requires basic knowledge. Consider the most common causes of engine failure, and do-it-yourself lawn mower repair in the field.

    Engine starts but does not hold load

    If the engine starts and runs at idle, but does not hold the load poorly during operation. Most likely, there is “oxygen starvation”. Such a do-it-yourself lawn mower repair is performed by replacing or cleaning the “blowing method” of the air filter.

    Mechanical repair for all types of lawn mowers

    Regardless of the type of engine, the mechanical part of the scythe includes knives, a device for ejection or accumulation of cut grass and a transmission mechanism. Most often, knives fail or line ends.

    Cleaning the mechanical part of the Bosh lawn mower

    Broken or bent knives are visible to the naked eye. Depending on the material and the degree of damage, the knives are replaced or restored by simply folding them back to their original state. With heavy wear, the cutting part can be sharpened. A do-it-yourself lawn mower from a trimmer can fail for many reasons. Most often this is an excess of the maximum permissible load on the torque and the engine, since a knife is used instead of a fishing line.

    Restoration of the throttle handle

    When inspecting, check the condition of the grass supply duct into the container and, if necessary, clean it. complex mechanical failures require a complex tool, special equipment, professional skills and it is better to entrust the elimination of such malfunctions to professionals.

    Engine starts and runs normally, but knives do not rotate

    In this case, failure of the mechanical part is guaranteed or, as an option, its attachment to the motor shaft is destroyed.
