Grinder trimmer

Summer is coming and the grass has already grown noticeably, so far this is not critical, but you should already think about how to cut it. I'll show you how to make a simple trimmer out of an angle grinder to cut the grass. More precisely, it will be a special device into which the grinder will be installed. After mowing, it can be removed again and used for its intended purpose. There is little point in buying a ready-made trimmer if you only need it 1-2 times a season.

How to make a trimmer from an angle grinder with your own hands

The first thing you need to do is a bracket to encircle the body of the angle grinder. To do this, take a steel plate and bend it on both sides along the body. I took the plate that was already bent on one side initially. Now all I have to do is fold the second edge.

I apply it to the body of the angle grinder. I use a marker to mark the bend.

Next, I clamp it in a vice and bend it with hammer blows. I saw off the excess with the same grinder.

The tool body has threaded holes on both sides. A handle is screwed into these holes to cut on both the left and right sides; the handle is reversible. It is precisely through these holes that the trimmer bracket will be fixed.
Holes must be drilled on the sides of the bracket so that they match the holes on the sides of the tool.We mark with a marker.

We drill while holding it in a vice.

Next, you need to attach a guide to the bracket along the length of the angle grinder body or shorter.

We weld it by welding. We knock off the scale and clean it with a metal brush.

Now the rod-handle. It will be made of steel pipe. We will make a bevel at the end of the pipe so that the handle is attached at an angle. Mark the cut line with a marker.

We saw off the corner.

We weld it by welding. We also knock off the scale with a hammer and clean it with a metal brush.

Now it’s time to install the grinder itself into its seat. To do this, unscrew the protective circle.

To keep the trimmer from touching the ground and at a certain distance, wheels will be attached to it. They can be taken from an old and unnecessary baby stroller or any other cart. As a last resort, make it yourself from wooden rounds.
I had the wheels along with the brackets.


We insert the grinder into the seat.

We attach the wheel with the bracket and fix it all with a bolt. Tighten well with a wrench. We do the same procedure on the opposite side.

The trimmer is almost ready to cut the grass.


All that remains is to make the cutting part. To do this, we take pieces of steel cable or specialized nylon wire for trimmers. We pass it crosswise through the clamping nut, through the holes for the key.

Screw the nut with the cutting cables onto the grinder.

We fix the wire with electrical tape.

You need to get a long extension cord and you can mow.

It mows quite tolerably.



Before I finish, I would like to say that the grinder is not designed for this kind of work. And if you want to repeat this homemade product, then you take full responsibility and use everything at your own peril and risk.
When mowing the grass, be very careful; a steel cable rotating at high speeds is very dangerous.Perform all manipulations to install or dismantle the cutting part only when the plug is unplugged from the socket.
But the device is necessary and may well be useful for you to mow the lawn in front of your house.
