How To Make A Snow Blower From A Large Angle Grinder

Every winter, after the first snow falls, you begin to think about buying a snow blower. The mechanism that throws snowball for you is the dream of many. The prices of similar equipment of ordinary people can drive into a stupor. Easier to do it yourself from an existing tool. Let the snow clear, and do something else. In the article, we will talk about how to make a snow thrower from a trimmer with your own hands.

"Snow thrower" from the trimmer and lawn mowers. the principle of its work

There are many options for making a snow blower from a lawn mowing. Let us dwell on the simplest method. Replace the cutting knife with the rotor. This snow blower will work like a regular shovel. You just don’t have to lift it, you just need to carry it on the ground. She will rake the snow, and throw it to the side.

Materials and Tools

We have a task: a do-it-yourself snow blower from a trimmer. One condition: the braid should be with a straight boom and gear on the end. It is desirable to have a multi-tooth disc in the kit, for mowing thick grass. Next, we buy beer, "Baltika" in a large tin barrel.

We are drinking. We get the main material. metal. Of the tools useful drill, angle grinder, welding machine.

Non-drinkers can replace the bottom of the barrel with sheet metal, 1.5 mm. Using welding to produce the necessary parts.

Step-by-step manufacturing of parts and assembly

We begin to create spare parts. We cut the barrel in a circle at a height of 150 mm from the bottom. From below we make a hole in which the protruding part of the trimmer reducer will enter. Drill 3 more small holes. They should be positioned so that they coincide with the holes for attaching the shield to the gearbox.

On the side we make a square slot, measuring 100 by 100 mm, to eject snow.

We close the upper open part of the workpiece, by a third, with a piece of tin. After making sure that the ejection gap is in the center of the closed part.

We make a rotor. We cut 4 pieces of rectangular shape, 250 per 100 mm. We give each disc the appearance of a blade by trimming one of the corners on the long side. We weld them to the trimmer disc with a cross. The rotor is ready.

The deflector responsible for the direction of the snow release will also be made from the remains of the barrel. Cut a strip of metal with a width of 150 mm and a length of 300 mm. Bend the workpiece slightly. We weld sidewalls with a height of 100 mm to it, preventing the spreading of snow at the exit.

The last thing to do is a spatula. We take a piece of metal with dimensions of 300 by 400 mm. Bend the edges. We get sides 20 mm high.

  • We take the case and weld the deflector to it, in the place where the slot for ejection.
  • From below we fix the shoulder blade.
  • We insert the trimmer reducer into the hole and fasten it with bolts.
  • We install the rotor, like a regular lawn mowing knife.

If this instruction is not enough for you, then you can always read this article, which discusses in more detail the process of assembling a shovel for a snow blower with your own hands.

Use this unit at full throttle. Frequent pulling the trigger will break the engine or clutch. Some of the readers may already have thought about purchasing a high-quality and reliable device that can last for many years, and if you are one of these people, follow the link and find out about Patriot self-propelled petrol snow blower.

Grinder. Snow Blower from Angle Grinder

The snow blower from the angle grinder is made on the basis of wooden sleds, to which the rest of the mechanism is attached. The design includes: a deflector, a rotor and its casing. A sheet of steel in the shape of a shovel is attached to the front. angle grinder plays the role of a drive, and is responsible for the rotation of the blades.

How does this miracle of technology work? The operator pushes the sled, raking the snow in front of him. The snow, having hit the shovel, enters the rotor blades and is thrown to the side.

The principle of operation of this device is very similar to the mechanical snow blower, which we will talk about here.

What and what to do

For assembly, you will need plywood, 20 mm thick, from which the sleigh and handle will be made. Sheet metal, 1–1.5 mm, is useful for the manufacture of the main parts of the apparatus and raking shovel. The metal tube is small in thickness. Semi-automatic welding machine. Drill, jigsaw and some hand tools.

Spare parts and assembly

Let’s start with the manufacture of the base. We saw two workpieces with a size of 610 per 100 mm with a jigsaw, cut one of the edges at 45 degrees. It will take two pieces of plywood, with a size of 370 by 50 mm, to connect them.

Another detail, 370 per 100, in which a semicircle is cut out according to the size of the body. Skids are ready, proceed to create a pen

From the same plywood sheet we make two bars 50 mm wide and long for the operator’s height.

Note that the handle will be at an angle relative to the runners. Its length can be measured experimentally.

A strong fastening of the handle will be provided by two more bars. a brace, of a similar width. Their length depends on the angle of the handle.

We make a scraper. Iron sheet 570 mm long and 150 mm wide. We bend it so that we get a shovel, with a base size of 370 mm, an initial side height of 100 mm and the opposite side of 570 mm.

We proceed to the manufacture of the main parts. We cut a strip of 330 mm long and 250 mm wide from metal. We turn the resulting workpiece into a ring. We fix using spot welding. We make the bottom for the learned pipe and weld it into place.

Now you need to make 2 holes. One will be in the center of the bottom. Its diameter should be equal to the protruding part of the gearbox cover angle grinder. Another hole is located on the side. Its dimensions are 150 by 200 mm.

We make a deflector, which is responsible for the direction of the ejection. It consists of a rectangular plate 420 by 150 mm and two side supports of a triangular shape. The long side of the triangle is 420 mm high 150 mm. At its base, you will have to cut a semicircle for a snug fit to the body.

The rotor will look like a disc with welded blades. Its diameter is 300 mm. You will also need to cut 4 blades in the form of a rectangular triangle, with a height of 100 mm and a base size of 277 mm. In the center of the disc, drill a 23 mm hole.

It is better to order a rotor in a turning workshop. If there are the slightest errors in the calculations, increased vibration will quickly ruin the gearbox.

The angle grinder will not have to be disassembled. The only thing to do is find 4 bolts. Their diameter and thread must coincide with the holes of the grinder reducer. Only the length should be at least twice as long.

  • Putting the foundation together. We fasten the runners together with the help of prepared bars. We fasten on self-tapping screws, one in the middle, the second at the end with a saw cut. We use the same fasteners to attach the handles and struts. We attach a metal pipe from above, connecting both handles.
  • We fix the scapula to the even ends of the runners. To increase the strength we use bolts with nuts.
  • We attach the spot deflector over the side opening of the body.
  • We attach the angle grinder to the body with the help of the elongated gearbox bolts. An additional mount would be appropriate. We make it from thin strips of metal. We bend in a half ring, put on the tool, and weld to the bottom of the body.
  • We put the rotor on the seat washer, angle grinder and tighten the clamping nut.
  • We weld two corners on each side to the body. We, in turn, fasten them to the skids so that the body fits snugly on the front block.
  • All parts of the resulting snowplow should be coated with paint. This will help extend their lifespan. As you may have noticed as a result, you get an aggregate of impressive size, but if you are the owner of a small territory, it is better to concentrate on assembling a mini snow blower with your own hands, because it is much easier to assemble, and to put it in the far corner of the garage after use.

    Snow mower

    By installing a blade, it is easy to make a snow blower out of a lawn mower. But she must be self-propelled. In this case, the mechanism moves due to the drive of the engine, and the snowball is raked by the shovel attached in front. A convenient solution for those who do not want to mutilate their instrument. Major changes to the design of the mower will not be made.

    The most unsuccessful mechanism for remaking a snow blower is a gas mower. The shaft of its engine is directed downward, which significantly reduces the design options of the future apparatus. You won’t be able to lay such an engine on one side, oil will flow, the engine will jam.

    The shaft is equipped with a special part that breaks when the load is exceeded, protecting the engine. Another thing is the snow blower from the Krot cultivator, which you can assemble with your own hands only by reading the instructions on this site.

    The necessary materials and tools to make a do-it-yourself snowplow

    We make a blade from a metal profile of 20 by 20 mm and a sheet of smooth roofing iron. Of the tools required: an angle grinder, a welding machine, a drill, a riveter and other hand tools.

    Step-by-step manufacturing of parts and assembly of a homemade snowplow

    We begin to cut the profile. We make 2 pieces 100 cm long and 4 50 cm long. Parts of shorter length should be bent, giving the shape of the future dump. Weld the resulting parts. Long pieces are arranged vertically above and below. A pair of short parts is located at the edges, remaining at an equal distance from the middle.

    We take a sheet of metal and cut a workpiece with a width of 100 cm and a height of 50 cm.

    On the contour, at a distance of 1 cm from the edge, drill holes. We attach the workpiece to the frame, drill a profile on the holes already obtained. Now we rivet the parts together.

    Fasteners are made of profile. We cut two pieces 20 cm long and a couple more, 30 cm. Different sizes are needed so that the raked snow goes to the side. We fasten them in the form of a corner, using spot welding. At a distance of 3 cm from the seam, we drill every detail.

    • We weld the fasteners to the shovel frame.
    • We put the blade to the lawn mower. In her body we make holes for fixing bolts.
    • We fasten the design.

    Remove the knife before starting the mower.


    These mechanisms have positive and negative qualities. We obtain a snow removal machine from the existing tool, at minimal cost. The device becomes multi-functional. But there is a minus. The equipment is not designed to work in winter, which means that its parts will wear out faster.

    With these devices it is easy to clean only loose dry snow. And as you may have noticed, you have to tinker before assembling the working unit, and some refuse to assemble with their own hands, but still plan to save money and it was for these purposes that an article was written in which we talk about the Husqvarna 227 snow blower, because unlike our counterparts this product costs much less.

    For the same reason, saving is quite simple in design and in the assembly with your own hands of a grass cutter from the washing machine.
