The snow season is the favorite time of children: skiing and sledding, fun snowball games and building ice castles ... But the owners of country houses are not very happy with the abundance of snow, because they have to take up a shovel and clear the territory again. It's good when you have the opportunity to buy a snowblower and turn your seasonal duty into a pleasant job. But if there is no extra money to buy a useful assistant, you can always make a snow blower with your own hands from materials that have been gathering dust idle for a long time in the corner of a workshop or a shed.
Construction # 1 - auger snow blower model
Preparation of basic elements
We propose to first consider the option of how to make a snow blower with your own hands based on an old engine from a walk-behind tractor. To do this, you need to prepare:
- Sheet (roofing) iron for assembling the auger body;
- Steel corner 50x50 mm for the frame of the structure;
- Plywood 10 mm thick for side parts;
- Half-inch pipe for equipping the handle of the machine.
When planning to equip a homemade snow blower with an air-cooled engine, it is imperative to provide additional protection for the air intake opening from small snow particles emitted during operation.
The engine power of this device is 6.5 hp. It is quite enough for cleaning fresh snow from the backyard area.
Thanks to the machine's working width of 50 cm, it will be convenient to move the structure and clear winding paths on the site. The machine has compact dimensions, its width does not exceed 65 cm. This allows you to hide the snow blower in the shed at any time as unnecessary, it easily passes through a regular doorway.
A ”tube can be used to make the auger shaft. A through-cut is made in the pipe, which is necessary to fix a metal blade with dimensions of 120x270 mm. In the process of work, the captured snow mass from the conveyor belt will be moved by the auger to the blade. This blade, in turn, under the action of the rotation of the shaft, will throw the snow to the sides.
The frame of the snow blower can be welded from steel corners of 50x50 mm, and closer to the edges of the structure in the pipe to the transverse corners, it remains only to weld two corners on each side, the dimensions of which are 25x25 mm
In the future, the engine platform will be attached to these corners. It is possible to fasten the transverse corners to the longitudinal ones and fix the control handles to them using bolts (M8).
The auger tube is equipped with a metal blade and four rubber rings d = 28 cm, the material for the manufacture of which can be a tire sidewall or a 1.5-meter conveyor belt with a thickness of 1.5 mm.
You can cut out rings from a rubber base using a simple device: drive two screws into the board, and then fasten this structure tightly to the tape and turn it in a circle. You can significantly simplify the cutting procedure using a jigsaw
Since the snow blower auger will rotate in self-aligning bearings 205, they must be placed on the pipe. In order to make a snow blower yourself, you can use any bearings, the main thing is that they must be closed. A support from the universal joint of old Zhiguli models can act as a protective casing for bearings.
Advice. In order for the structure to fit well into the bearings, you need to make a couple of cuts in it and tap it lightly. Such manipulations make it possible to slightly reduce the diameter of the shaft.
To insure a homemade auger from ice ingress, it is advisable to provide a safety pin. In addition to its direct purpose - cutting off when the auger is jammed, it will serve as a belt fuse (if you equip a belt drive system). The auger can also be driven by a chain. Its idling speed is about 800 rpm. All the necessary components for a snow blower can be purchased at any specialized store.
A piece of plastic sewer pipe d = 160 mm is well suited for throwing snow. It is fixed on a pipe of the same diameter, placed on the auger body itself
The continuation of this section of the pipe will be a chute for ejection of snow, the diameter of which must be larger than the width of the metal blade of the auger.
Assembling the structure
Before assembling the structure, it is necessary to pay attention to the fact that the dimensions of the machine body should exceed the dimensions of the auger itself by a couple of centimeters. This will prevent the mechanism from touching the walls of the case during operation.
Since the snow blower engine can be used for other purposes during snowless periods, it is advisable to provide a quick-detachable convenient platform in the design of the unit, thanks to which the engine can be removed at any time without using any tools.
A significant advantage of this design solution is the ease of cleaning the body and moving parts of the machine from compacted snow. And it is much easier to put away such a snow blower for storage: just remove the engine and the car will become twice as light.
The basis for skis is wooden beams, which are additionally equipped with plastic pads. You can make such overlays from the wiring box
The snow blower is now ready for use. It remains only to paint the homemade device and get to work on clearing the snow.
Construction # 2 - rotary snow blower Blizzard
This device, which is quite simple in design, can be made in any workshop equipped with a lathe and a welding machine. The snow collector, designed by the Penza craftsmen, showed itself well even in rather difficult snow conditions.
The design of the device is based on: an engine with a built-in muffler, a gas tank and a cable for controlling the throttle valve.
All components of the device can be purchased in the store or taken from the same bike
To begin with, you need to make a rotor on a lathe on the basis of a corresponding workpiece from an electric motor part. Outwardly, it looks like a steel disc d = 290 mm and 2 mm thick. The disk, connected with the hub by means of bolts, forms a structure, to which 5 blades are already attached by welding. To increase the efficiency of the mechanism, the blades are additionally reinforced with stiffeners on the reverse side.
The cooling system of the motor works on the principle of a fan, the blades of which are made of duralumin and are fixed on the pulley to start the motor
The fan is protected by a soldered casing located on the crankcase cover. To improve the quality of cooling, the cylinder head is placed at an angle of 90 degrees.
The shaft is mounted on the rotor housing on four ball bearings arranged in pairs. It is fixed to the body with a steel retaining ring and bolts. The rotor body itself is pressed against the frame using a special bracket, which partially captures the pressure ring.
Assembly diagrams of the main elements of the Blizzard snowplow
Removable elements of the machine are the aluminum wall of the rotor housing and the scrapers placed along the frame.
A significant advantage of a home-made snowblower is the ability to adjust the working width by changing the scrapers. At the height and quality characteristics of the unit. The weight of the structure does not exceed 18 kg, which makes it possible to use it for women, and the range of snow throwing is about 8 meters.

Before you make a snowplow with your own hands, you need to understand the principle of operation and design features of this device.
Any snow blower is a device that collects and throws aside the snow mass.
The design of this unit consists of three main modules:
- A device for collecting and transporting snow.
- Frame for attaching the mechanical and power parts of the snow blower, as well as the base for moving the unit around the site.
Let's consider the types and design of each module in more detail.
The electric drive is suitable for clearing the snow mass of garden paths, a small area, putting things in order near a house or garage. Disadvantages: tied to the power grid, insufficient performance.
The snow blowers assembled on the basis of an internal combustion engine are distinguished by their autonomy, high power and the ability to control the shaft speed. Disadvantages: difficulties with starting in the cold, heavy weight, the need to refuel.
This is the most important unit of any self-assembled snow blower, because the weight, dimensions and efficiency of the entire device, as well as the operator's safety, depend on its design and quality of performance.
There are four design options for the snow blower:
- Combined two-stage.
Rotary snow blower
This is a very simple device, the basis of which is an impeller with blades, enclosed in a casing. The impeller is fixed directly on the engine shaft using the principle of axial fan blades. To increase the snow coverage, specially shaped guides are attached to the casing and frame.
An electric motor or an internal combustion engine can be used as a power drive for a rotary snow blower.
To avoid short circuits and electric shock to the operator, the electric motor and all electronic components require good protection from moisture and snow. It is better to entrust the connection and electrical insulation of the power plant to professionals.
Auger snow blower
It is much more difficult to make such a model with your own hands. This device consists of a steel body, inside which a double-thread auger rotates, moving the snow to the center of the structure. The blades are responsible for removing the mass, rigidly fixed on the central part of the shaft.
The auger is made of metal and can have a smooth or serrated surface. The first option is suitable for removing fresh snow with a toothed auger - for removing compacted mass with an ice crust. As a power plant, it is better to use a chainsaw engine, which, through a standard chain, will transmit rotation to the shaft.
These models combine an auger and a rotary snow blower. The auger scoops up the snow to the center of the box, and the rotor blades throw the mass to the side. This design is considered the most effective, but also more difficult for self-assembly.
The best option for a power plant for a two-stage cleaner is the motor cultivator, since it contains a power take-off shaft, which is necessary to drive the auger mechanism. If the farm has the necessary tools and materials, it is quite easy to make a combined snow blower for a walk-behind tractor with your own hands.
Drawings of this design are presented below:
- The body is made of roofing iron. A hole is made in the central part for installing the rotor.
- The auger is made from a steel strip, which is welded to the shaft with a double helix. The direction of the turns is towards the center of the structure.
- To install the shaft into the housing, blind pins are used, into which the bearings are pressed.
- Depending on the location of the drive, an asterisk is welded onto the auger shaft, which will be connected by means of a chain transmission to the sprocket of the power take-off shaft.
- The frame with runners and the attachment of the snow blower nozzle are assembled from a steel corner.
In reality, it is a symbiosis of auger construction and a sweeper. In this solution, a brush is installed instead of a spiral knife. The body of the cleaner is placed at an angle to the frame to throw snow outside the area to be cleaned. Such a constructive solution is often used as a nozzle for small agricultural machines that are idle in the winter and can be quite successfully used to remove the snow mass. It is quite simple to make a brush for a walk-behind tractor with your own hands. It is necessary to weld steel plates on four sides of the shaft, which will serve as the basis for attaching polymer bristles.
In terms of efficiency, such a brush cannot be compared with production samples, but due to the high speed, it will be very good to clean the garden paths from shallow snow.
Depending on the solution chosen and the type of power plant, frame materials and a base for moving the device are selected. The frame is assembled from ½ or ¾ inch diameter steel pipe. The structure is mounted on a wheelbase or runners, which are attached to the frame in the manner of a children's sled. In some cases, it will be appropriate to use a steel angle instead of a pipe. A frame made of such a material can be bolted together without using a welding machine.
Detailed description of methods
Bulldozer homemade snow blower for walk-behind tractor.
The dozer blade is made of steel sheet. Measured according to the drawing. It is welded. The blade is attached to the walk-behind tractor with brackets with rods, which will need to be made. The lower part of the blade is a knife. They cut off the snow and take it to the side. Pass the rods (device for turning) from the blade into the eyes in the blade and pass through the attached tubes to the control. For convenience, a stroller is made from different parts, consisting of a frame, two additional (rear) wheels, a seat. The frame is attached to the walk-behind tractor hinged. Ahead - a dump controlled through the traction of the walk-behind tractor. The handles of the walk-behind tractor are the steering wheels of the device. The two rear wheels are spaced apart for stability. The wheels of the walk-behind tractor become the front wheels of a homemade bulldozer - a snowplow.
Auger snow-removing motoblock.
A box for the auger is made of steel sheet. At the bottom, the box is like skis. Lugs are made in the box from the sides through which the shaft will be threaded. On top of the shaft inside the box there will be a metal tube on which the auger elements are welded: 2 metal rings each. Weld the grip on the tube in the center. It is made of two pieces of a light angle, connected together, welded, and welded to the tube. At the end, it is advisable to weld the main structural element - a gripper spatula. Do it so that there is a minimum distance between the blade and the back wall of the box.
To this structure, welded in the middle of the pipe, the outermost inner ends of the auger blades are welded. The other ends of the auger (right and left) are welded to the tube, reinforce the weld with an additional strip of steel on both sides. On the right and left sides - spirals towards each other. We insert the finished auger into the casing. A shaft is inserted through a tube (screw axis) with welded spirals and gripper structures. Through the side lugs.
The tube with welded elements is located inside on the shaft, in the gap between the inner walls. We drill a tube and a shaft along the edges. We fix the shaft with the tube with two bolts and nuts. At the walls of the box, where the shaft is threaded, we make fasteners. The seats (glasses) on the shaft must have bearings. Bearings in cups must be of a closed type. To prevent snow from falling into the bearings. The shaft should protrude from the box body. The auger for the walk-behind tractor is fixed.
Place a pulley or sprocket on the end of the shaft. For belt or chain transmission.
Connect the created system with the walk-behind tractor mechanism. Chain or belt drive. If there is a pulley below, then the A100 belt will go, for transmission from the walk-behind tractor. Make a swivel gutter from a plastic pipe for plumbing. Attach a snow chute to it. It should be wider than the width of the auger. To prevent the auger from getting clogged with snow. Additionally: the wheels of the walk-behind tractor can be replaced with skis. You need to make compact wide short skis for a walk-behind tractor. Then the snow will be easy to clean. You can also leave the wheels if the surface to be cleaned is smooth, for example, asphalt.
Fan snow thrower for walk-behind tractor.
First, an oval box is made of metal to suck in snow. On the rear side of the box, with different tricks, it is necessary to mount a glass with a bearing (bearing - closed), together with a fan impeller. Protect the fan with a grill (cover). Bearings (4 pieces - in pairs on both sides) hold the shaft inside, on which the fan is put on. The rear of the shaft is fixed in a bracket where two sealed bearings are located. The shaft protrudes from the device. At its end there is a gear or an asterisk, from where the transmission goes through a belt or chain to the driving mechanism of the walk-behind tractor. In the oval box, next to the fan, there is a wide opening at the top. A light curved pipe is inserted into it. Wide enough to prevent the snow being thrown out from getting stuck. The mounted snow blower for the walk-behind tractor is ready.
Auger-fan (rotary) - mixed method.
To make such a mechanism, it is necessary to complete all the work with the creation of a screw device, adding to it a rotary fan method. We measure it out. From metal we make a box of certain sizes for the auger. Initially, in the box at the top, we outline the place for the outlet pipe. We make a corresponding hole in the casing.
Let's start creating auger... We select the shaft and the tube on the shaft with the expectation that the tube will sit on the shaft without backlash, it will be very tight. Since the shaft will sit on bearings on both sides of the box, it is necessary to make the shaft so long that it is slightly longer in length than the width of the casing. The tube should be the same size as the box, but still slightly smaller. So that when the shaft is twisted, the ends of the tube do not touch the box. Now we make parts for the auger. The trunnions are made of 2mm steel. We cut two rings of steel on one side. Gently turn the open ring with a spiral. Two spirals - we connect the rings, weld together. We get one spiral in two turns - for one side of the auger.
We do the same with two more rings made of two-millimeter steel. Two spirals are obtained for both sides of the auger. Now we make one more detail - a snow thrower. From two corners, with the letter P, we weld them together, at the end we weld a spatula. We weld this part to the tube, in the center. Everything must be measured and done so that the assembled blade part in the center of the auger is at a minimum distance from the rear wall of the box.
The spatula was welded. We weld the studs made with a spiral. Spirals - they look at each other, inside. The inner ends of the spirals are welded to the snow thrower. External - to the tube, reinforced with steel strips.
We push the finished structure into the casing. We pass the shaft through the sides of the casing and through the tube. We fix the shaft with the tube with two pins made of bolts and nuts on both sides, having previously drilled through them.
We make glasses for bearings on both sides. We fasten bearings (closed type) on the shaft in glasses. On one side of the shaft, we attach an asterisk or a pulley (for a chain or belt drive). We connect the gear - with a chain or a belt with the propeller of the walk-behind tractor. The mounted snow blower for the walk-behind tractor is almost ready. We make a wide large metal ring on top of the casing. Weld over the hole in the casing. Attach a rotor with a fan to the side of the ring. Connect it to the mover of the walk-behind tractor. Here you can use chain transmission. Cover all moving parts with guards. Insert a plastic plumbing pipe into the outlet. Secure. And work. Brush the snow.
The cost of such self-made units is several times cheaper than store-bought ones. If a used store costs 18,000 rubles, then parts, material for homemade ones will cost many times cheaper. Moreover, store shops do not always meet the criteria for snow removal in our open spaces. These are undeniable benefits. The disadvantage is that it does not always work out what is intended.
Naturally, there are no analogues of homemade products. This is exclusive.
Each master comes up with his own. If done well, wisely, the unit will last a long time.

Homemade snow blowers are popular among owners of summer cottages and private houses. And this is not at all surprising, since each owner of his site in the winter almost daily independently removes his territory from snow. This can be done manually with a shovel, or you can make a do-it-yourself snow blower to make the job easier.
Types of snow blowers for the T-25 tractor
All snow blowers for T-25 tractors can be divided according to their type:
- plows, which in turn can be rotary and straight
- rotary, milling and auger snow blowers
- cleaning brushes.
Snow dump on T-25
This can be said to be the simplest design of a snow blower for the T-25. The blade is a mounted harvesting unit that is attached to the front or rear of the tractor. Hydraulic steering allows blade angle control directly from the operator's cab.
It is the dumps that the owners most often make on their own, exposing their drawings and plans for collecting equipment on forums and in discussions. Thus, each owner can choose the desired blade width and height, mounting method and other technical characteristics.
Summing up: the necessary set of tools and the economic benefits of homemade products
To make homemade snow blowers, you need a minimum set of tools:
- Welding inverter.
- Powerful drill or drilling machine.
- A set of locksmith tools.
- Consumables - cutting discs, electrodes, drills, etc.
Most likely turning work is indispensable... If you do not have a familiar turner or your own lathe, you will have to order metal processing, and this is an additional cost. In addition, you will need parts from old mechanisms or decommissioned auto and motor vehicles. But the main thing is that you need a gasoline engine or a walk-behind tractor. If the farm does not have "unnecessary" units lying around, then they will have to be bought. This will lead to an increase in the cost of homemade products. Do not forget about time costs.
Therefore, before taking on the manufacture of a homemade snow blower, evaluate your strengths, weighing all the pros and cons and knock out the estimate. If costs exceed profitability, then you can consider buying a new or used snow blower. Moreover, there is no need to chase after famous European or Japanese expensive brands, with a bunch of additional (and often unnecessary options). The experience of the portal users says that the "honest, proven Chinese" perfectly cleans the snow on the site.
