Grass trimmer from the angle grinder with his own hands. DIY
As the basis, which will be used to make a lawnmower with their own hands, you can take the chassis from an old wheelchair, the basis from a wheelbarrow or a similar unit of another kind. In this case, it will be enough if the width of the working strip will be 50 cm.
For your information. The wheels not only provide a way to move the device during work, but also regulate the height at which the knives will rotate. It is usually assumed that it is enough to install the blades at a height of 6 cm.
If you install the mower on two wheels, it will make it more maneuverable and allow you to change the angle of the device in the process of work. This will help when working on difficult surfaces or in the presence of a large number of obstacles.
If you use a four-wheel lawnmower, it will make its movement more even and stable. There are also variants that involve the installation of three wheels.
Petrol-powered machines are self-contained
The design of the lawnmower provides that the wheels can be taken those used in a wheelchair, wheelbarrow or other similar devices. It is possible to make them yourself. To do this, you can cut the wheels out of thick plywood and install them on bearings.
Sometimes make a grass collector for the lawnmower with their own hands.
It is important to take into account! Gasoline-powered devices are the most self-contained. However, they are heavy and clumsy. They usually have a four-wheeled metal base. They are difficult to use for mowing lawns that have a difficult surface.
The most maneuverable are devices that run on an electric motor, which provides power from a battery. Usually such lawnmowers use a two-wheeled base. This makes it possible to work in areas with pits or hills, as well as in narrow passageways or where there are many trees or other similar obstacles.

Design and manufacturing features of the grass chopper
There are two types of grass cutters: gasoline and electric. The former allows you to perform work in any place of the site. The machine copes not only with grass, but also with branches. The latter is tied to the place, although less heavy. The quality depends on the power of the engine.
The principle of operation of the shredder is similar to the kitchen combine. The grass is placed in the tank, in which the knives are located. The electric motor drives the shaft. The blades begin to rotate and shred the grass. The design consists of:
Experts recommend installing a 3,000-watt motor with 1,500 rpm. The higher the speed, the better the waste will be shredded, and the haulm will not wind up on the shaft. In the homestead, the grass chopper is used for:
How to make a knife for a grass trimmer: materials
The blade of the homemade grass trimmer is attached to the drill with a nut and bolt, which is clamped in the chuck. Be sure not to forget and install the blade guard on the grass trimmer beforehand, to ensure your own safety while cutting the grass.
The blade of your grass trimmer can be made of tool steel or another very tough material. You should know that the smaller the thickness of the grass trimmer blade, the better it will cope with cutting the grass. Grass trimmer blade length depends primarily on the blade guard and the working width of the mowed grass. Most often the grass trimmer blade length does not exceed 30 centimeters.
Grass trimmer blade with their own hands
If you need to mow plants with thick or stiff stems, an ordinary trimmer line will not do the job. So you can’t do without a special metal blade. Grass trimmer blades can be bought in a specialized store, or you can make your own, for example, from an old circular saw blade (without tips). The blade is made as follows.
- First, a marking is made on the disc. You can make as many “petals” as you like, such as two, three, four, or five, as in this description.
- Next, using the angle grinder, make 2 radial cuts according to the markings.
- After the radial cuts, you must use the same angle grinder to connect the 2 notches, making a longitudinal groove deep enough so that you can break off the cut piece of the blade.
- Clamp the part of the workpiece that is almost cut off in a vice and break it off.
- Do this operation with all the “petals” of the future knife. Any irregularities can be ground on an emery wheel.
- When ready, sharpen one side of each “petal” at a 45° angle.
Let’s make a reliable mower with our own hands
To create an island of family well-being, a beautiful well-groomed area, using a minimum of manual labor, every owner dreams. Lawnmower with their own hands. one of the ways of rational use of nodes from abandoned mechanisms.

Motivation for making a tool from hand-made materials
First of all, it is necessary to determine what tool will effectively replace the usual hand-held mower in the care of the site. Perhaps dense planting, frequent bushes and flowerbeds will not provide access to the mowed area, and then the “swirls” of grass will need to be removed manually. A lawn mower with your own hands should be assembled for mowing an area larger than 4 acres.
choose the way of driving the cutters. the basis for assembling the necessary assemblies. The blades can be set in motion:
- due to manual action, pushing forward the mechanism, which requires great physical strength;
- Using electric power of single-phase or three-phase current;
- the motor from the battery;
- using an internal combustion engine, two or four stroke.
Having decided on the energy component, it will be necessary to choose wheels, handle, platform to collect the lawnmower with their own hands. Assemble the necessary fasteners and components of the wiring, protection, and connection diagram.
Principles of using electric motors
The electric motor can be single-phase, operating from 220 V mains, or three-phase. When connecting the motor, all safety rules for working with electrical appliances must be observed. RCD protection must be provided for a single-phase motor, and a powerful three-phase motor must have capacitors of appropriate capacity in the circuit.
For an electric lawnmower with your own hands, you can use a powerful slow-speed drill with a speed of 1500-3000 rpm. It is necessary to choose the right ratio of power to the width of mowing, so as not to overload the motor.
Installed on the platform, a cordless or cordless drill will create the necessary torque, and the grass will be mowed. During work, do not forget to observe rest intervals, to cool the brush motor.
Such a tool will help to clean the adjacent territory, it is easy to fold and does not require much space for storage. The platform on which the motor is mounted should be narrow, so that a walled area can be treated.
Stability depends on the location of the center of gravity. The lower it is, the less tipping moment the platform has. How to properly cost a lawn mower with their own hands, look at

How to make a trimmer for grass from the angle grinder with his hands
The first thing you need to do is a bracket to enclose the body of the angle grinder. To do this, take the steel plate and bend on both sides along the body. I took the plate already bent on one side originally. Now I only have to bend the second edge.
The tool body has threaded holes on both sides. A handle is screwed into these holes to saw both the left side and the right side, the handle is made flip. It is just for these holes and will be fixed trimmer clamp for grass.It is necessary to drill holes on the sides of the bracket, so that they coincide with the holes on the sides of the tool. Mark it with a marker.
Now the handle bar. It will be made of a steel tube. At the end of the tube we make a bevel, so that the handle is attached at an angle. Mark the line for the trimmer cut with a marker.
Now it’s time to install the angle grinder in the seat. To do this, unscrew the protective circle.
So that the grass trimmer doesn’t touch the ground and is at a certain distance, wheels will be attached to it. They can be taken from an old and unnecessary baby carriage or any other cart. In a pinch, you can make it yourself from wooden circles.I had the wheels with brackets.
We put the wheel with the bracket and fix it with the bolt. Tighten them well with a wrench. The same procedure is done with the opposite side.
It remains to make a cutting part. For this we take sections of steel wire or a specialized kapron wire for trimmers. We pass a crosswise through the clamping nut, through the holes for the wrench.
Before I finish, I would like to say that the angle grinder is not designed for this kind of work. And if you want to repeat this homemade, you take full responsibility and use everything at your own risk.When mowing the grass be very careful, rotating at high speed steel wire is very dangerous. All manipulations on mounting or dismounting of the cutting part should be done only when the plug is unplugged from the socket.But it’s a useful device and it can be useful for cutting the lawn in front of the house.
What kind of homemade angle grinder can be made?
Given the high speed of the engine and its power, as well as the presence of a special reducer, from the angle grinder come out excellent machines and devices.
We should probably start with self-made trimmers, which are sure to be useful in the household, such as a self-made trimmer for grass.
Grass trimmer from the angle grinder
Self-made trimmer for grass Using an angle grinder is not particularly difficult to produce. Its only disadvantage is the need for power, and a long extension cord. To make a trimmer for grass from the angle grinder with your own hands, you will have to construct a long and strong handle, with one edge of which, metal clamps could be attached to the tool in question.
However, it is best to be reinsured and make a special metal mount with wheels, for installation of angle grinder. At the top of the mount should be welded a piece of pipe to connect a long handle of plastic or wood. An important feature of the grass trimmer from the angle grinder is that to mow the grass, it is best to use not a fishing line for the trimmer, but a thin cable.
Lawn mower from an angle grinder
reliability, and safety, has a lawnmower from the angle grinder. Such a tool for mowing the grass is very stable and convenient to work, it does not need to be carried all the time in your hands. The designs of homemade mowers and schemes on the Internet, not counting. However, they all boil down to the same.
The base. for its manufacture can adapt the old unnecessary wheelbarrow Kravchuchku or make their own hands from a piece of thick plywood, sheet steel and other materials. On top of the base is securely fixed angle grinder, the shaft of which is passed through the hole, down.
On the shaft of the angle grinder securely fixed adapter for installing sharp knives, which can be made from a thin steel sheet. By the way, the design of such a mower has already been described earlier, in the last issue of the construction magazine, an article about DIY from a washing machine.
On top, it is better to immediately cover the angle grinder sealed housing to avoid getting into the motor and gearbox, grass and debris. To control the homemade lawnmower from the angle grinder, you must also provide a button to turn on and off on the handle, in a convenient location, or a socket for connecting an extension cord.
Grit grinder from an angle grinder
If you are engaged in housekeeping and you have to prepare food for animals all the time, then the homemade grain grinder from the angle grinder, made by your own hands, will be very helpful.
To make a homemade grain grinder, you will need the following materials:
- Thin tin for making a body with a sieve and a grain receiver;
- Plywood to cut the base under the grain grinder;
- Steel for making knives or ready-made versions of them from the vegetable slicer.
So, let’s start with the fun part, making the base. For this you will need to take a rectangular piece of plywood, size 50 by 40 cm. Closer to the edge, it will be necessary to attach the angle grinder and trace its contours to cut the hole in the plywood. Subsequently, the angle grinder will be fixed directly in the hole by means of metal bolts and a plate.
Then you can start making the body, where the grinding of the grain will take place. It is best to make it out of thin tin. After making the body, many holes should be drilled in the bottom, no more than 3 mm in diameter. Through the holes, like in a sieve, the grain, crushed by the knives of the grain grinder, will pass.
Blades, as it was said above, it is better to make them from a strip of thin steel. For the convenience of attachment, you can fix the knife directly with a nut from an angle grinder, having previously made a hole suitable for the diameter of the rod. Now it remains to make the receiver for filling the grain into the grain crusher. You can also make it out of tin or a 5-liter plastic bottle with the bottom cut off.
