If a beautiful green area is arranged next to the house, it participates in creating a harmonious design of the area. A neatly trimmed lawn with emerald grass can create a sense of comfort for the owners and guests of this house. In order to maintain its appearance, it is necessary to regularly mow the grass. The ability to use a lawnmower for this purpose turns long and tedious work into an easy task.

The device of homemade lawn mowers

You can buy a well-known brand lawn mower for mowing lawns. However, this will require significant costs. Another way to use this device is to make it yourself.

Homemade lawn mower

An alternative to using a lawn mower is to use a scythe. Not everyone can use this opportunity. The ability to use a scythe must be learned. In addition, it must be borne in mind that with inept use of this tool, it is easy to injure yourself or those around you.

The lawn mower is free from such disadvantages. Instead, it has the following advantages:

  1. The grass is cut at the same height.
  2. Working with a lawn mower requires much less effort than using a scythe.
  3. Relatively high speed of work.
  4. Most models used have a grass catcher. This eliminates the need to collect the mowed grass after the end of the lawn mowing. In the process of work, it automatically falls into the grass catcher.

Note. When planning the design of the site, the lawn is usually assigned the role of a beautiful background. It sets off the beauty of more striking garden or park design elements.

A homemade lawn mower should include components:

  1. The rotation of the knives that cut the grass is carried out by a motor, which is set in such a way that its axis is vertical. The scheme provides that it can be a gasoline or electric motor.
  2. In the process, the knives rotate in a horizontal plane, cutting off the grass. They move at a high speed corresponding to the rotational speed of the motor. In practice, they can be of several types: metal or in the form of a fishing line. The latter work no less effectively than metal ones, but when hitting stones or other obstacles, they only bend without damage.
  3. The metal frame is the base on which all the parts of the device in question are attached. In particular, a hole is drilled here to secure the motor.
  4. Wheels must be attached to the frame. Possible designs that move on two or four wheels.
  5. When using an electric motor, it is necessary to use various control elements: power cable, switch and others.
  6. The control handle is needed so that the operator guides the mower in the desired direction.

DIY options

DIY garden shredder

As a basis, with which a do-it-yourself lawn mower will be made, you can take a chassis from an old stroller, a base from a wheelbarrow, or a similar assembly of another kind. In this case, it will be enough if the width of the working strip is 50 cm.

Note. The wheels not only provide a way to move the device during operation, but also adjust the height at which the knives will rotate. It is usually assumed that this is sufficient to set the knives at a height of 6 cm.

Installing the mower on two wheels will make it more maneuverable and allow you to change the angle of inclination of the device during operation. This will help when working on difficult surfaces or when there are many obstacles.

Using a four-wheel lawnmower will make it run more smoothly and steadily. There are also options that provide for the installation of three wheels.

Devices with a gasoline engine are autonomous.

The device of the lawn mower provides that the wheels can be taken those that are used in a wheelchair, on a wheelbarrow or other similar devices. You can make them yourself. To do this, wheels can be cut out of thick plywood and mounted on bearings.

Sometimes they make a grass catcher for a lawn mower with their own hands.

It is important to consider! The most autonomous are devices with a gasoline engine. However, they are heavy and unwieldy. Usually they make a four-wheeled metal base. It is difficult to use them for mowing lawns with difficult surfaces.

The most maneuverable devices are considered to be powered by an electric motor, which is powered by a battery. Typically, these lawn mowers use a two-wheel base. This makes it possible to work in areas with holes or hills, as well as in narrow passages or where there are many trees or other similar obstacles.

Self-assembly of the lawn mower

DIY cultivator

Different types of self-made lawn mowers are made in a similar way. Usually a motor is used, which is taken from old and non-working structures. There are several popular options for self-manufacturing this device.

From an old washing machine

Note. Do-it-yourself electric lawn mower can be made with a motor from a washing machine.

As a motor, you can use one that was taken from an old washing machine. It is quite heavy, so it is installed on a steel sheet with a hole drilled in it to transfer rotation to the knives.

For the operation of the electric motor, it is necessary to make a cylindrical steel casing.

Chainsaw Friendship and Ural

Important! The rotation of the lawn mower can be ensured not only with the help of electricity, but also by using a gasoline engine. One of the possible functional options is the use of the one available in the Druzhba or Ural chainsaw.

Here's how to assemble this type of lawnmower: One of the options for this self-propelled home construction is to use a steel rectangular frame. It is made from pieces of a metal profile. Since the structure is relatively heavy, it is recommended to use four wheels to move it.

Two rotating braids can be positioned at the front of the frame as shown in the drawing. The motor is installed so that the axis of rotation is vertical. Rotation to the knives is transmitted using a belt drive.

Note. You can use the engine from Kama.

One option for making knives is to use 25cm pieces of bicycle chain. You can also use a centrifuge with knives. At high rotation speeds, these knives will cut the grass efficiently.

A home-made lawn mower with a gasoline engine has good autonomy during operation and has high power. The disadvantage of a self-made gasoline lawn mower is the large weight of the device.

From the grinder

Lawn mower from the grinder

A lawn mower is made from a grinder as follows. Usually, in this case, the motor is installed on a metal base to which two wheels are attached.The motor from the grinder has an elongated shape. It is positioned horizontally in such a way that its front part protrudes slightly forward above the metal sheet. The axis of rotation of the motor must point downwards. You do not need to use the shaft here.

A metal strip is used as knives in a lawn mower from a grinder with your own hands. It is sharpened along the edges, a hole is drilled in the center for mechanical attachment to the motor axis.

From trimmer

Note. When making a lawn mower from a trimmer with your own hands, you can use an engine taken from an old trimmer in the design. The principle of its manufacture is practically no different from other design options.

In this case, you can make a wooden axle, to which you need to attach bearings with wheels, a hole is made in the center of this axle, into which you need to insert a handle. Knives in the form of line segments are attached to the motor axis. When rotated, centrifugal force straightens them, and they cut the grass at high speed.

From an old vacuum cleaner

This self-made lawn mower option differs in that the motor used in this device is taken from an old vacuum cleaner. It is placed vertically on a flat metal sheet.

A hole is drilled for the axis of rotation of the motor. The height of the wheels is selected in such a way that the lower part of the axle is at a distance of at least 4 cm from the ground.

As knives, you can remake a narrow steel plate, which is attached to the middle of the motor axis.

From a drill

You can use an electric motor from a drill. The rotation speed is usually in the range of 1500 to 3000 rpm. For effective work, it is necessary to determine the ratio of power and length of the knives. The latter circumstance determines the width of the strip within which the grass will be cut. If the width is too wide, it can happen that the motor from the electric drill does not have enough power.

Important! When operating such a mower, rest periods must be provided. This is to prevent overheating of the engine.

Such a motor runs on a battery. From time to time, it requires manual recharging from the mains. The absence of the need to use a power cord for homemade products makes such a lawn mower sufficiently autonomous for as long as there is enough battery to work.

DIY lawn mower knife

For DIY lawn mower, it is recommended to use an electric asynchronous motor. It will be enough if its rotation speed is 3000 rpm.

Important! The quality of grass mowing is determined not only by the speed of rotation of the knives, but also by the width of their capture. The larger it is, the higher the linear speed of the knives, which means the quality with which they cut the grass.

It will be convenient to use a strip of tool steel as knives. Its width can be from 20 to 50 mm. For the motor axis, a hole is drilled in the middle to attach the knives.

One of the options for using knives is to cut them out of an old hacksaw. Such parts require steel that is hard, but not brittle. Otherwise, if the knives hit a stone during rotation, they will break. A piece of a knife flying to the side in such a situation can injure a person.

Note. If the blades of the knives are slightly curved downwards, then the grass will not wind up so much on the axle during operation.

Self-production of such devices does not cause any particular difficulties. This requires an engine that can be removed from old and unnecessary equipment. Making such a device yourself means getting high-quality equipment, while saving a significant amount of money.
