Devices for snow removal are quite in demand today. They may differ in their design and the way the work is performed. If you wish, you can make a snow blower with your own hands from a chainsaw; such a machine will do an excellent job of clearing paths.
Design and operating principle
To make a snow blower, you must first complete the diagrams of the components and make calculations. The frame and body are made from a used chainsaw. It must have a working motor, and the more powerful it is, the more productive the snow blower will be. In addition to the motor, the frame needs to be welded for the device. To make the unit move itself, it can be equipped with a drive and wheels can be installed. It would be better to make skis from below. Then the chainsaw snow blower can be pushed and it will go through the snow.
The body is made from metal sheet. The auger scoops up snow using discs, crushes it, and then two blades push the mass through the sleeve through rotation. You can equip homemade snow blowers with a rotary attachment. Then they will function like a vacuum cleaner.
The rotor is made of wings with welded blades. The nozzle is placed in the housing, and then attached to the back of the screw mechanism assembly. As the rotor rotates, it sucks in snow that comes from the auger. Then with air flow snow comes out through the sleeve. The driver regulates the snow release with a visor located on the sleeve. For ease of use, you can make a device that can be rotated.

Creating a Snow Blower Frame and Auger
To make a snow blower from a chainsaw, you first need to make a frame and an auger. The operation of the entire structure depends on the strength of the frame, since other systems are welded to it. It is necessary to use pipes of the same width.
Prices for ready-made models snow removal equipment forcing many to take up a shovel and clear paths by hand. To mechanize the process with minimal financial costs, you can design a snow blower with your own hands. The first step is to evaluate own strength, available material and equipment. Based on the conditions - select optimal project implementation, develop a drawing, study manufacturing technology and draw up a snowplow assembly plan.
Manufacturing technology of auger snow blower
A manual auger-type snow blower is distinguished by its simple design and the possibility of self-production. To operate the mechanism, it is equipped with an engine from a walk-behind tractor, chainsaw, rotary hammer or drill. The type of engine determines the power supply of the unit: electric or fuel.
Homemade auger-type snow blower
Design and principle of operation of the equipment
Auger snow removal units perform a single-stage intake and discharge of snow. The shape of the working mechanism of a snow blower resembles the shaft of a mechanical meat grinder. The auger is located at the front of the machine; the rotating element is closed on the sides and top by a bucket body.
Monolithic device spins around its axis, grinds the snow and transfers it inside the equipment, and then throws it into the distance through a bucket. To improve the removal of compacted snow and ice, the snow blower is additionally equipped with a knife or augers with a serrated edge are used.
In addition to the rotating shaft, the homemade snow blower is equipped with:
- engine;
- outlet chute;
- box;
- wheels or tracks;
- handle for movement.
Construction of auger snow blower
Preparation of tools and materials
Before you make a snow blower with your own hands, you need to draw up a drawing, calculate the consumption of materials and prepare the tools.
To make small snow removal equipment with a working width of 50 cm, you can use the engine from an existing walk-behind tractor. It can be replaced with any engine with a power of about 1 kW. To create the remaining components you will need:
- The auger body is roofing sheet iron, the sides are thick plywood 1 cm thick.
- The design of the auger, as can be seen from the do-it-yourself snow blower drawing, includes the following elements:
- the central axis is a metal pipe with a diameter of ¾ inches;
- spatula – metal plate 12*27 cm;
- two-way screw rotation system - conveyor belt or sheet metal;
- sealed bearings 205;
- auger drive – belt or chain.
- Frame – metal corners 5*5 cm, crossbars – corners 2.5*2.5 cm.
- Platform for engine installation – metal corners 5*5 cm.
- Snow chute - sewer PVC pipe diameter 16 cm.
- Ski track – wooden beams with plastic covers.
- The control handle is a half-inch metal pipe.
- The transverse corners and the handle are fastened with M8 bolts.
Assembly diagram for auger snow blower
Tools you will need:
- welding machine;
- drill and grinder for metal;
- hammer and square;
- jigsaw or saw;
- metal clamps.

Creating a Snow Blower Frame and Auger
The frame itself resembles an ordinary sled - everything structural elements placed on two skids. To save time, you can use an old sled with a metal frame.
Making a homemade frame with dimensions of 70*48 cm:
- According to the drawing, prepare parts from the corners required length.
- Connect them together and weld them.
- Make holes in the side posts for mounting the bucket, handle and wheels.
The technology for creating a snow blower auger with your own hands is more complex. The blades of the working element can be made from old tire, conveyor belt or sheet metal. Last option more reliable and provides better cleaning snow.
Important! The double-sided blades should be angled towards the center, allowing you to transform rotational energy to linear. The blades rotate and push the snow masses in a straight line towards the bucket.
Making a blade from a tire
The general algorithm for creating a screw does not depend on the material used:
- Cut 4 circles from metal, the diameter of which is less than the semicircle of the bucket. According to the example under consideration, the diameter of the rings is 28 cm.
- In the center of the circles, cut holes corresponding to the diameter of the axle, that is, ¾ inches.
- Cut each circle on one side and stretch it, forming a spiral.
- Weld a metal plate in the center of the auger shaft. This paddle will feed the snow to the bucket.
- Weld the prepared spirals to the shaft.
- Attach a sprocket or pulley to one side of the shaft - the choice depends on the type of drive (chain or belt, respectively).
- Put on the drive and install the bearings.
The next stage is making the bucket:
- Bend a sheet of sheet metal 50 cm wide into a semicircle, the diameter of the arc is 30 cm.
- Cut out the sides of the plywood and prepare holes for the shaft in them.
- Connect the bucket parts, move the installed bearings to the end walls and attach them.
Attaching the auger shaft to the bucket
Assembling the structure and starting the unit
To put a self-made snow blower into operation, you need to assemble the structure together:
- Attach the finished bucket with the auger to the “sleigh”.
- Install the engine by putting the drive, which is removed from the auger, onto the pulley or sprocket from it.
- Attach a handle to the frame and display engine controls on its panel.
Ready unit before start-up
Before starting, it is necessary to check the strength of the welds, the reliability of the fastenings and the movement of the blades - they must rotate freely.

Making a snow blower attachment for a walk-behind tractor
IN winter time year, the walk-behind tractor can be converted to use as snow removal equipment. You don't have to buy expensive attachments for this. Having experience working with metal, you will be able to independently transform the walk-behind tractor into an effective snow blower.
Design of an auger-rotary snow blower
Rotary mounted “snow blower” for walk-behind tractor
Rotary nozzle - a two-stage model, the most complex in self-production. A snow blower for a walk-behind tractor of this type consists of two working elements: an auger and a screw. Rotating auger blades transfer snow masses to a high-speed impeller, where they are further crushed and thrown through a bucket. This principle of operation increases the productivity of the equipment and the range of snow throw (up to 12 m).
Rotor shaft diagram
The entire creation process is divided into two stages:
- Making a bucket with a working mechanism.
- Connection between walk-behind tractor and snow blower.
Drawing of a rotary snow blower: side view
Sequence of manufacturing a rotary canopy:
- According to the drawings of a snow blower for a walk-behind tractor, prepare the parts of the box, drum for the rotor and pipes from sheet metal.
- Make a casing from metal 1.5-2 mm thick to accommodate the auger. The bucket is assembled from a curved central part and end cheeks. Cut holes on the sides for the auger shaft. The impeller casing will also serve as a support for the drum and rotor.
- Make a screw shaft.
- Cut 8 half-disks from 2 mm thick steel.
- Weld the spiral augers to the metal pipe.
- Place the shaft with the augers on ball bearings 203.
- Creating and attaching the rotor:
- As a drum, you can use a 20 liter aluminum boiler or a metal cylinder made of sheet metal.
- Connect the prepared drum to the snow blower body.
- The rotor is assembled by welding from profiled metal strips, a disk, a shaft and bearings, as shown in the diagram.

Homemade rotor for a snow blower
The design of a self-made rotary snow blower is attached to a walk-behind tractor using a profile and an angle bolted connection. The torque is recreated through a V-belt connection. The A-100 belt is suitable for this purpose.
Connecting the walk-behind tractor and snow removal attachment
Creating a bulldozer-type blade
It is much easier to manufacture a bulldozer-type blade or a snow shovel for a walk-behind tractor. Homemade unit works in three positions: forward, left and right at a slope of 30°.
To create a blade with a working width of 850 cm you will need:
- steel barrel 200 l;
- square pipe with a cross section of 4*4 cm - 85 cm;
- iron sheet 3 mm thick, size 85*10 cm;
- M8, M10 and M12 bolts, nuts and washers;
- tools for working with metal (welding machine, grinder, pliers, etc.).
“Cut” the barrels into three segments
Work order:
- Cut off the bottom and lid from the barrel.
- Cut the resulting cylinder into three equal segments.
- Fold the two segments together and weld around the perimeter - a rigid sheet 3 mm thick is formed.
- To strengthen the lower part of the blade, attach a knife - a strip of steel 5 mm thick. The cutter fixation step is 10 cm. homemade knife put on rubber gaskets.
- Weld a 40*40 mm pipe along the center of the dump.
- Fix a semicircle of thick-walled material to the pipe by welding metal sheet. Make three holes in the installed arc, allowing you to change the direction of the shovel.
- Make a holder from a pipe with a cross section of 40*40 mm L-shape. One end is bolted to the frame with holes on the blade, and the other to the walk-behind tractor.

Additionally, the device can be equipped with a folding sleeve that will regulate the direction of the snow.
Modification of a trimmer for a snow blower
You can make your own electric snow blower from a grass trimmer. A unit with the engine located on top is optimal. An electric motor with a power of 1.6 kW is enough for the “snow blower” to throw snow masses 3-4 meters.
Considering design feature electric engine, the snow removal mechanism can be made rotary - without installing a screw shaft. Interesting option working chamber-bucket - use of a ventilation “snail”. Snow will be thrown out through the existing socket. The size of the installation allows it to be controlled manually.
The rotor is made of four metal blades, the length of which must correspond to the diameter of the base of the “snail”. The trimmer gearbox is installed in an improvised bucket, and a rotary mechanism is attached in place of the blade from the brush cutter.
Important! When creating a snow blower from a trimmer Special attention should be given to the power wire. The cable must be of sufficient length and high quality - it will face aggressive operating conditions.
Electric snow blower
Design features of an electric snow blower:
- optimal power electric motor – 2.2 kW;
- The power unit must be protected from snow and water - otherwise there is a high probability short circuit;
- the engine should be placed above the snow removal level;
- The wire must withstand cold down to – 60°C.
Making a snow blower with your own hands - not an easy task. If technical knowledge and design experience are insufficient, then it is better not to take on such work. However, if you have the skills to weld and create metal products, it will be possible to make a practical and economical unit.
In the territory Russian Federation falls in winter a large number of snow. In some places the precipitation reaches a height of a meter or more. It is in such conditions that a snow blower is simply an irreplaceable thing. The market offers a large assortment of snow removal equipment of varying power, household and semi-professional types. However, not everyone will be able to allocate a sufficient amount of money to purchase expensive foreign cars. One of the options for obtaining a snow blower could be homemade version made from a chainsaw.
How to assemble a snow blower with your own hands?
Having understood the design of snow blowers and familiarized yourself with the drawings from the Internet, you can build a snow blower with your own hands using a chainsaw. Even a beginner can easily master this homemade product. Having a number at hand necessary components, tools and spare parts, you can construct a homemade snow blower.
The only difficulty you may encounter is finding a power unit. However, any motor of domestic or foreign chainsaws is suitable for these purposes. On forums and on many websites you can find various schemes and drawings that show what components are needed and how to connect them together.
Choosing a chainsaw for a homemade snow blower
The power and performance of a snow blower directly depends on the engine you choose. This main element is removed from the chainsaw. The higher the power of the saw, the better. The engines in household models are two-stroke, power varies from 2 to 10 horsepower. For a homemade snow blower, 5 horsepower will be quite enough. Below we will consider the most popular brands chainsaws, which are often used for homemade snow blowers.
Chainsaw “Friendship”
This chainsaw was developed back in USSR time, in 1950, after which they began to produce them en masse in the Soviet Union. Since then technical indicators and the characteristics of the saw are significantly outdated. The weight of the unit is 12 kg, in addition, the saw has large dimensions. Experienced owners say that the first saws, which were assembled in the first decade of the plant’s existence, still work properly.
However, chainsaws produced after 1990 are characterized by frequent defects, regular breakdowns, malfunctions and a short service life.
Gasoline saw “Ural”
Another representative of the domestic production of chainsaws. “Ural” tools can be called a kind of improvement on “Druzhba” saws. With the same weight, the Ural has more power from a two-stroke gasoline engine (5.5 horsepower) and smaller dimensions. In this regard, the performance of these devices is much higher.
German chainsaw “Stihl”
Imported sawing equipment is often much better in quality and performance. Foreign factories, such as the German concern Stihl, always try to produce technological innovations. Of course, this also affects the cost of the equipment. Shtil is one of the most popular companies among the Russian population, because it has high power, excellent quality, long term service and a relatively low price.
What does it take to make a snow blower?
Next, using an example, we will look at assembling a snow blower with our own hands based on a Ural chainsaw. The fact is that in this particular chainsaw the inertial clutch in some cases acts as a kind of fuse, protecting the rotor from breakdowns and malfunctions. The equipment motor is equipped with a 1:2 reduction gearbox.
Our goal is to create reliable and productive snow removal equipment with our own hands on a budget.
To do this, we will try to use accessible and cheap materials:
- aluminum and metal pipes;
- metal sheets;
- bearings and fastenings;
- chainsaw motor;
- welding;
- improvised tools.
The assembly process itself is not particularly difficult, so every man could successfully make a snow blower with his own hands at home. You don't need any special skills to do this. If you don’t know how to properly operate some tools, you can watch a couple of video lessons on this topic.
Diagrams, drawings and principles of assembling a homemade snow blower
On the Internet, on forums and discussions, you can find many drawings of a snow blower made from a chainsaw with your own hands. In our example, consider the following diagrams:
The engine itself must be placed on the longitudinal axis for reliability and quality of operation. In addition to the motor, use a fuel tank from a Ural chainsaw, securing it to the steering support with two bolts. The control handles can be taken from the motorcycle. To create a bucket you will need pipes with square section 20x20x1.7mm, from which the frame is designed and covered with a tin sheet, the thickness of which is not less than 0.5 mm.
Below are drawings for assembling the most important part of the snow blower - the auger rotor.
You can make an auger with your own hands from the following parts:
- shaft in the form of a ½ pipe;
- a driven sprocket mounted on the shaft;
- two bearings mounted on the housing;
- rotor wing 30x4 mm;
- rotor blades, 2 pcs;
- auger blades, 8 pcs;
- wings for blades, 4 pcs;
- support corners, 2 pcs.
The blades can be made from duralumin sheet, the thickness of which is 4 mm. Using jigsaws you cut out a kind of horseshoe. You will make the fastening process much easier if you cut them individually rather than as a single piece. Below are drawings of the rotary auger blades.
As described above, when creating blades, it is better to cut them separately, in the form of horseshoes, and attach them to the shaft. However, some users cut out rings from a metal sheet using a grinder and a jigsaw, and then stretch them into a spiral with a vice. This method is more effective, but significantly more difficult in terms of physical activity.

Small-sized snow blowers that allow you to automate the labor-intensive process of clearing snow are in great demand. But what to do if you simply don’t have the funds to buy a snow blower?
The only way out is the design of a homemade snow blower from what can be found in almost every thrifty owner’s garage. Eg, chainsaw, which is available to many people, especially in rural areas.
Principle of operation
The design of a factory snow blower is quite simple. The main driving force is the motor, the power of which will determine the quality of snow removal, throw distance, etc.
In addition to the engine, snow blower device includes:
- A housing made of metal or plastic that protects working components from foreign environments.
- A screw mechanism consisting of a shaft and screw parts.
- An outlet pipe through which snow is thrown out.
- If the system is two-stage, then in addition to the auger, an impeller (rotary mechanism) is also used, which throws snow into the outlet pipe.
- Basic control systems, handles, clutch, etc.
- Depending on the configuration, a wheelbase, tracks or skis may be present.
The operating principle of a homemade snow blower will be no different from the store-bought version. It also comes with the auger will enter, which is directed with screws to the center of the shaft. It directs the snow cover to the blade, which transfers the mass further to the outlet pipe.
If the design includes a rotor, then the incoming snow from the blade falls first on it. It performs additional processing of the snow mass, after which it is sent into the pipe.
Then the snow is thrown out to a certain distance (up to 12 meters).
Manufactured homemade a chainsaw snow blower has its advantages:
- By making your own snow blower, you can save a lot of money that you would otherwise have spent on purchasing a new snow blower. At the same time, even if you have to buy the chainsaw itself (see), you will still remain in the black.
- A snow blower made by yourself from or other models will have similar performance as purchased counterparts.
- The remaining parts of the body, the screw mechanism and other structural components are made from readily available materials, such as metal pipes, iron sheets, etc. This is again about saving.
You will find more complete information in the video below:
The only drawback will be the fact that a homemade snowblower made from a chainsaw it will not be possible to install the mechanism responsible for the self-propelled structure. But if you provide a kind of sled or skis at the bottom of the unit, then this task will not be so difficult.
The chainsaw snow blower has other features:
- Almost any pipe can be used as an outlet pipe. plastic pipe, the diameter of which will be at least 16 cm.
- The control handle can be made independently, from any metal tube.
- The width of the bucket will depend on the power of the chainsaw engine. If it is powerful enough, the width of the bucket can be increased.
Due to the fact that a homemade snow blower made with your own hands from a chainsaw is not self-propelled, it is better provide a kind of skid for better movement of the unit on the snow cover. You can use regular wooden blocks, corresponding to the frame length.
You can attach them plastic base, which will improve the running performance of the snow blower.
You can select some tips, helping in the operation of the unit:
- To prevent foreign objects from getting into a running engine, you can install special safety bolts that eliminate this threat.
- After starting the unit for the first time, you need to check all connections of the snow blower. If required, tighten all nuts fully.
- Give preference to bearings closed type so that the snow mass does not get inside the housing.
- Do not try to remove heavily compacted snow. Do preliminary preparation coating using hand tools.
Conclusion
Constructing a homemade snowblower from an existing chainsaw is a fairly optimal way out of a situation where there is not enough Money to buy a snow blower in a store.
Considering that the cost of even the cheapest unit can be at least 15 thousand rubles, this issue becomes quite acute. (read about choosing a gasoline snow blower)
Another good thing about using a chainsaw engine is that its power is enough to remove fairly large volumes of snow. At the same time, the power of a homemade snow blower is almost identical to that available from store-bought models (see snow blower).
