We offer everyone who wants to make a snow blower for a walk-behind tractor with their own hands, so that they will once and for all get rid of dependence on snow drifts and plans in the country and keep the access roads to the house in excellent condition..
Yes, you can just go to a special store and buy an industrial snow blower, but such a choice will entail significant costs when a self-made snow blower will help not only clear the snow on your site, but also save you from “unnecessary garbage” that will become part of the snow blower ! Why “rubbish”? Yes, because at the household men on the site you can find a lot of “necessary”, but not yet used things! And these things in a whole pile sometimes wait in the wings …
What are snow blowers
- Air-ventilation type – snow masses with great force are drawn in from one side and thrown out on the other, according to the principle of a vacuum cleaner;
- Auger – the auger captures the snow masses and, advancing along its entire length, throws it in the other direction;
- Bulldozer – a blade is installed in front of the unit, which captures and removes snow from the road;
- Fan-blade – hitting the fan blades, the snow rises into a special inclined pipe and is thrown through it to the side.

DIY snow blower for walk-behind tractor, drawings
To make the device of all these types of snow blowers more understandable, let’s take a closer look at the drawings of these mechanisms with you:
Rotary snow blowers
If we convinced you of the need to make a snow blower for a walk-behind tractor with your own hands, then prepare all the necessary tools:
- All kinds of keys;
- Fixed bolts and nuts;
- Drill;
- Grinder;
- Screwdrivers of all sizes;
- File and hammer;
- Vise and pliers;
- Electrohock;
- Chains;
- Welding machine – as without it;
- Metal sheet and shaped pipe.
In order to make a snow blower for a walk-behind tractor with your own hands, you need to understand the principle of its operation, now we will tell you about it and we can get to work.
Rotary snow blower, working principle
The most popular are rotary snow blowers, since they are the ones who are able to throw snow to the greatest distance from the walk-behind tractor, sometimes the range of snow “flight” can reach up to 12 m.
A rotary snow blower is a conventional metal body in which a rotating auger shaft is fixed. Snow masses are captured by the augers and move to the impeller, where they are captured by its blades and fed first into the cavity of the mechanism, and then into the exhaust pipe.
Thanks to the reliable and powerful adapter and belt system, this snow throw is quite powerful..
In order for the snow blower to work, you need to make the correct connection through the belt transmission of two shafts: one – a walk-behind tractor, with the second – a snow blower.
How to make a snow blower for a walk-behind tractor with your own hands
To begin with, we return to the drawings and approach the lathe with them, which, of course, “accidentally” stands in your workshop. And now, working strictly according to the drawings, we are sculpting all the attachment parts of the future snow removal unit. If there is no lathe – do not be sad, turn to turners for help, they will gladly and for a reasonable fee grind all the necessary parts for you..
Now you need to make the most important part of the snow blower – the auger shaft! You will need a metal pipe with two trunnions at its ends, and 8 pieces of half-discs made of steel with a thickness of 2 mm. From this all the goodness, you will make screws, and then weld them to the pipe, as shown in the figure..
You should have a double helix..
After your hard work is crowned with success – we start assembling.
We put the shaft with augers on ball bearings No. 203, aluminum AMg3, or AMgb, is ideal for the glass body. Everything is bolted to the sides of the unit. The snow is captured by the augers and fed to the rotor. To correctly make a drum in which the rotor rotates, it is enough to get an aluminum 20 l boiler. Attach this boiler to the snow thrower body using 4mm rivets. Thanks to such a device, and special blades, the snow entering the drum will go on a “long-distance flight at 3 – 8 m from the snow blower.!
And now let’s get down to connecting together two units, a walk-behind tractor and a snow blower! Do not forget about the torque, which can be recreated in a snow blower using a special A-100 belt with a pulley of the right size. Our V-belt drive transmits torque first from the engine to the shaft of the walk-behind tractor, and then to the shaft of the snow blower – everything worked out!
All shafts and augers, transmissions, we must place in a reliable metal case, steel 2 mm thick is ideal. Take the sheets and weld them so that the corners are 20x20mm. Rivets with a diameter of 4mm and special M4 screws will help to fasten the joints. Put the unit on homemade skis.
