  1. Availability. Absolutely all materials can be found at your site or bought at the acceptance of secondary raw materials for a few pennies.
    Simplicity of design. You can make a lawn mower out of a washing machine from improvised materials. No complex calculations and geometric problems. Everything can be done on the knee with a hammer and screwdriver.

Making a lawn mower from a washing machine

To make such a device, we need an unnecessary old washing machine. No, we will not attach wheels and a cutting knife to it! We need her as a donor of an electric motor for a lawn mower. We collect our thoughts, and with serious intentions we set off to work miracles.

STEP 1: electric motor. We disassemble the body of the machine and remove from there an electric motor with a starting relay. It is important to keep the motor wiring intact so that there are no connection problems in the future.

STEP 2: case. To make a reliable and durable body of a homemade lawn mower with our own hands, we need a sheet of metal of at least 4 mm. The dimensions of this sheet should be 300 x 400 mm. We prepare the body for further installation of the engine and wheels.

Note: if you have not found a sheet of metal suitable for the thickness, then you can take a sheet with a smaller thickness and reinforce it around the perimeter with a bar or piece of reinforcement.

STEP 3: install motor and start relay. At this stage of the step-by-step instructions, we install the main element of the lawn mower — the engine from the washing machine. We mark the body. We draw two diagonals and find the center of the rectangle. In the center of the body of the lawn mower from the washing machine, you need to make a hole for the motor shaft. Next, we install the motor itself. In our case, it is fastened with standard mounting bolts through spacers from nuts. This is a fairly simple, and at the same time reliable method of fastening. We attach a start relay next to the engine.

STEP 4: wheels. Wheels are an important part of the lawnmower design. There may be two, three or four. The most optimal is 4 wheels. This ensures maximum stability of the lawn mower unit. Wheels should be 10 to 15 cm in diameter. The height of the cut grass depends on the size of the wheel. We fix the axles of the wheels at the corners of the rectangular body.

STEP 5: homemade pen. To make it convenient to operate our lawn mower, you need to make a comfortable handle. You can take a ready-made handle from a baby stroller or make it yourself from a thin pipe. We will go the second way, and do it ourselves. There is nothing difficult in this. We make the handle so that it is convenient to control the lawn mower. Tightly weld or screw the handle to the body of the lawn mower.

At this stage, we have already figured out how to make a lawn mower with our own hands, but there is one more touch, without which the mower will not be able to mow — this is a knife. This is what we will do in the next section. But now you can already see all our efforts that were applied to the manufacture of this device. If you find any dubious or unreliable places, then it is better to remove them before putting the lawn mower into operation so that no problems arise.


I put a polypropylene fitting on the pulley, heated it with a soldering iron, drilled through the hole with a bolt, and stopped it, since the disk turns like a flywheel be healthy. The saw blade was put on through a 50 mm spacer. There is almost no beating in diameter, but up and down, a spread of 7 mm turned out, well, not critical, there is no turning. He also left the height of the grass bevel 4.5 cm. The passage increased, and the weight, too, was 16-17 kg.

Due to the circular saw, it works like a flywheel, even with thick grass the disc slows down but does not stop due to inertia. With this motor, I passed all 180 m2 and did not get very hot — you can go without a break.


When mowing with a disc, the grass on the lawn remains uneven, as a result, the knife was redone, made from a hacksaw blade for wood. After mowing, I was pleased with the result, but it is not clear why the saw blade does not give such a result. As a result, now I use the knife as in the picture and the result is excellent, it spins up in a split second, but it still stops on large grass, since there is no inertia like on a disk.
