How to Weld a Reducer Angle Grinder To a Trimmer
Types of snow removal equipment for the home do-it-yourself
Snowplows are provided for the mechanical removal of snow cover in the required area. Their functions include collecting snow mass and folding it to the place of collection. The engine that drives the machine can be electric or gasoline. And the snow-removing equipment itself is divided into self-propelled (with tracked or wheel drive), with manual control, one-stage and two-stage.
For self-assembly of such gardening equipment, you can use the engine from a chainsaw, an electric motor or a tiller, as well as various helpers that everyone probably has on the farm.
Before you make a snow blower with your own hands, you should familiarize yourself with the varieties of such equipment and choose an acceptable option for yourself.
The choice of design of the snow blower depends on almost all the reasons, one of which is the area of the plot that is supposed to be processed
Electric snowblowers are able to clean small areas near the house, for example, a porch or narrow paths. For exemption from the snow cover of an area of impressive size, such an aggregate is not suitable. In addition, his work does not differ in efficiency, if there are frost or significant snowdrifts.
On the other hand, similar equipment is quite small-sized, easy to operate and comfortable to store.
With the removal of a huge amount of snow from large areas, self-propelled gasoline powered snowplows are perfectly controlled. Moving without the help of others, these devices have a good cross and a large emission range. The technique has a rather huge size, but when working completely does not need to use physical effort.
Before you make a manual snow blower with your own hands, it must be borne in mind that non-self-propelled models are provided for cleaning small areas of freshly fallen snow up to 25-30 cm wide.
They are mainly used for daily cleaning of sidewalks, garden paths and flat roofs. Such devices are quite maneuverable, but when removing a dense layer it will be difficult to control the equipment, since you will have to push not only the device, but also the thickness of the snow in front of it.

Useful advice! When assembling a non-self-propelled snowplow for a home with your own hands, you should use the most lightweight parts possible, since the equipment will work at the expense of human efforts.
How to make a DIY homemade snow blower
Making a homemade do-it-yourself snow blower for your home is a good opportunity not to splurge on purchasing expensive models from leading manufacturers and at the same time avoid laborious clearing the area from snow with a shovel.
In addition, the equipment of its own production will be the subject of pride of at least some owner of a suburban house or cottage.
It will not be difficult to assemble a homemade snowplow if you have an idea of the principle of operation of such equipment and its structure. To clear the snow from the surface of the paths and yard of your own house, it will be enough to assemble a screw or rotary model. It’s easy on the device of the machine and make them a strength for everyone. Making a handmade improvised snow blower with your own hands is somewhat more difficult, but you can cope with this if you wish.
Snowplows can be either self-propelled. Wheeled or tracked, or non-self-propelled, the movement of which requires operator effort
Before you make a snowplow with your own hands, you need to determine the type of motor.
Equipping the equipment with an internal combustion engine, it should be borne in mind that this will be a rather powerful unit that will be able to work on any surface of your site. But, components and fuel for it are quite expensive. In addition, the shortcomings include a complex technical technique.
As for the do-it-yourself snowplow with an electric motor, then in this case you can use at least some motor from a comparatively massive electrical equipment.
Suitable engine from a trimmer or saw. The advantages of this technique include the availability of electricity, and the shortcomings. A small radius of action. To cover the whole terrain, you will need an extension cord or street wiring with several outlets.
Rotary Snow Blower
Making a snow blower do-it-yourself from a chainsaw
The main advantages of a homemade chainsaw snow blower are:
- Low cost of devices (in addition, you can buy a used chainsaw at a low price);
- High performance of the unit;
- The ability to make the main nodes from available at hand c.
The disadvantage is the inability to provide the apparatus with self-propelled movement.
When making a snow blower from a chainsaw with its own hands, its motor is used as a driving force.
To adapt the engine from such equipment to a snowplow, you need to disconnect it from the frame and slightly upgrade. Motor power will affect the main characteristics of the snow blower: the quality of clearing, emission spectrum and other parameters.
In addition to the motor, the design of the snow blower includes:
- Auger housing (bucket). It can be made of roofing sheet metal;
- Auger shaft. A pipe with a diameter of 20 mm (¾ inch) is suitable;
- Screw surface of the screw. Is made of sheet iron, some use a conveyor belt;
Chainsaw-based motor design is an economical option for a homemade snow blower
- Side parts. For their production use 10 mm plywood or sheet steel;
- Supporting structure (frame). It is welded from a profile pipe (angle 50 x 50 mm);
- Handle. From a pipe with a diameter of 15 mm (½ inch);
- A blade for feeding snow into the exhaust chute. An iron plate 120 x 270 mm.
In the work, you can use the drawings of a snow blower from a chainsaw with your own hands, posted by users on the Internet.
Do-it-yourself screw auger formation: step-by-step
The main working element of the snowplow is the auger.
It is a cutting ring-blades attached to the drive shaft. A pipe with a length of about 80 cm is used as a shaft. It is necessary to saw a through hole in the center of the pipe, into which a blade for feeding snow will then be inserted. When the shaft (pipe) rotates, the blade will recline the snow.
Before you make a screw for a snow blower with your own hands, you need to create a diagram or use ready-made drawings, according to which the rings will be cut. The auger blades are made of sheet steel. For this, 4 disks are cut out of the alloy, cut and pulled in the form of a coil. After this, the finished parts of the spiral are welded to the pipe: equally on each side.
Screw mechanism for the snow blower: 1, 11. Halves of the end bearing housing (steel, sheet s2, 4 pcs.); 2. End axis (steel, d30 bar, 2 pcs.); 3. Auger shaft (steel, pipe 42×6.5, 2 pcs.); 4.13. Mb studs (steel, d6 bar, 36 pcs.); 5, 17. Screws (steel, sheet s2); 6. The central axis (steel, d40 bar); 7, 16. Central bearing housings; 8. Asterisk (z = 36, t = 19.05); 9. Nut M36x3; 10. Bearing 160205 (4 pcs.); 12. M8 bolt (6 pcs.); 14, 15. Bearings 236205
Further, having determined the center of the shaft, two blades are welded in parallel to each other, which will throw out snow.
Iron spacers are welded along the edges of the pipe to fix the screw structure. Spiral-shaped blades on one side are attached to struts, on the other. To the central blades.
Useful advice! When making a screw for a snowmobile from a chainsaw with your own hands, it is extremely important that the turns of the iron spiral are placed at the same distance from the center and towards it. Otherwise, the equipment will vibrate violently.
In the manufacture of the housing of the screw, its length is left equal to the length of the shaft, taking into account the length for the drive. Axles are welded to the edges of the shaft, with which it is mounted on bearings.
They are used in closed execution to avoid the ingress of snow and water. You can get a good idea about the manufacture of the auger if you watch the of a homemade snow blower: it will be much easier to assemble a snow blower with your own hands in this case.
Homemade chainsaw snow blower
The manufacture of the auger housing begins with the sidewalls. For this, two circles are cut out of the alloy, the diameter of which exceeds the diameter of the screw assembly by 6-7 cm. An alloy sheet of the appropriate size is welded to the sidewalls. In the center of the side parts, holes are arranged in which the screw mechanism is inserted. Bearings are welded to the sidewalls from the outside.
In the pipe section under the drive, the driven sprocket is fixed by welding (an asterisk, for example, from a motorcycle, is suitable).
Next, proceed to the snow removal device. It can be made of a pipe with a diameter of 100 mm and a length of about 1 m. In order to install the pipe, an opening of the corresponding diameter is made in the screw housing. It must be on the back wall of the housing. A snow thrower pipe is inserted into this hole, fixed with bolts, and a box is installed on top.
The frame for the snowthrower is made by welding into the frame of profile pipes. To the transverse corners of the frame are attached strips for mounting the motor.
It should be noted that the power plant must move freely along the frame and be able to be locked in a suitable position. A handle is welded to the frame with the throttle control of the motor of homemade snow removal equipment brought to it.
Homemade snow chainsaw engine with a longitudinal engine
Depending on the type of terrain, the base of the snow blower is equipped with wheels or runners.
For flat areas, you can use wheels, for uneven and uneven surfaces. Runners. The base for runners is made of bars, to which plastic plates are attached for good gliding.
Do-it-yourself snowplow: advantages of the electric model
Electric snow blowers have some advantages over models equipped with internal combustion engines. These include:
- Relatively quiet work;
- Due to the absence of filters, fuel, spark plugs in the engine, such units are easy to maintain and maintain;
- No need to refuel;
- Low weight of equipment;
- During work do not emit smoke;
- Low costs and good efficiency.
Low noise and low construction weight are some of the main advantages of the electric snow blower
However, electric snow blowers also have flaws, among which:
- Low motor power (up to 2 kW);
- Continuous monitoring of the state of the power cable for damage;
- Small radius of action (as far as the carrying length allows);
- The need to use force to move the device.
Useful advice! Before you make a snow blower with an electric motor, select the wires whose insulation will withstand the load and will not crack under the influence of frost.
DIY electric snow blower assembly
The technology for the production of electric snow removal equipment with one’s own hands is largely identical to the device of gasoline models, but the electric motor acts as a driving force for such equipment.
It can be a simple engine from a saw, an angle grinder or another power tool. Refer to your own assembly drawings of the electric snow blower. clips on the topic will help to avoid installation errors.
An example of an electric snow blower device: 1. An electric motor; 2. A pulley from the car; 3. Sewer plastic pipe; 4. Semi-tap; 5. Steering wheel; 6. Packet switch
The design of the screw assembly and the housing can be assembled, as in the example of a snowplow based on a chainsaw. It remains to connect the electric motor. This can be done by various methods: a gearbox or belt drive. In the first embodiment, the axis of rotation of the motor is perpendicular to the pipe (shaft).
The auger rotates thanks to a gearbox that connects the shaft and the axis of the electric motor.
The second option implies that the axis of the motor and the screw shaft are parallel and connected by a belt. This scheme allows you to quickly remove and mount the electric motor, adjusting the tension of the belt drive. For work, you can use ready-made drawings, which can be adjusted to fit your size.
Starting to self-assembly, you should adhere to some recommendations:
- To avoid damage to the motor as a result of pebbles and other objects falling into the auger, use safety sleeves and bolts. Due to this, if the overload is exceeded, the bolts will fail, and the engine will not jam;
- The width of the screw housing is selected taking into account the size of the surface that requires cleaning;
- When installing a single-stage snow blower, the exhaust chute should be placed on top and on the side of the casing, which will allow the snow to be thrown to pass the smallest distance.
The engine of the snow blower can be gasoline or electric
DIY snow trimmer layout
To assemble a homemade snow blower from a trimmer, not all models of electric braids are suitable.
If the trimmer has a curved rod with rotation transmission with an iron cable, then such a tool is low-power and is not suitable for the production of a snow blower. One of the requirements is the presence of a straight rod on the trimmer and transmission of rotation from the motor to the coil by means of a gearbox and a solid shaft. Such devices are the most massive and can be used for snow plows.
Before you make a snowblower yourself from a trimmer, you need to check the availability of all the necessary tools.
A welding machine, angle grinder, drill will come in handy for you. The sequence of work is as follows:
- The body can be made of a small iron barrel, which must be cut approximately 15 cm from the bottom. A hole is arranged in the center of the bottom of the barrel into which a protruding gear element will be placed. Holes are drilled along the edges. At a distance coinciding with the flap mounts on the gearbox itself;
- On the side of the barrel, a square hole of 10 x 10 cm in size is made to tilt the snow mass;
Do-it-yourself snow blower
- The third part of the open casing should be covered with a sheet of tin so that the hole for the exit of snow is strictly in the center;
- Four blades come in handy for rotor production.
It is necessary to cut four rectangular plates of 25 x 10 cm in size from the sheet alloy. These blanks must be cut so that the shape of the blade comes out. After that, they are welded to the trimmer disc;
The blade is fixed from below. The gearbox is bolted. The rotor is installed as a trimmer knife.
A more thoroughly familiarized with the assembly action will help the of a snow blower from a trimmer do it yourself.
DIY rotary snow blower device
The main components of a do-it-yourself homemade rotary snow blower are:
- An internal combustion engine equipped with a silencer;
- Fuel tank;
- Throttle control cable.
For the production of all parts of the snowthrower, you will need a lathe.
Measures for the design of a rotary snow plow can be divided into several stages:
- Screw assembly;
- Rotor manufacturing;
- Housing installation;
- Frame device.
Having made each node separately, they are assembled in one design.
So that the snow blower has a presentable appearance, it is painted after assembly.

Making devices for a rotary snow blower
The production technology of the auger mechanism is similar to that of a auger for a snowplow from a chainsaw.
As screw blades, a dense (10 mm thick) conveyor belt can be used. The dimensions of the screw assembly must correspond to the dimensions in the drawings.
The rotor is made of sheet alloy 2.5-3 mm wide. Using a compass, you need to draw a circle of a suitable diameter on the sheet and cut out its angle grinder. To make the blades, take the workpiece from the electric motor for the base. Blades are formed from a sheet alloy. They are welded at an equidistant distance from each other to an iron disk connected to the hub.
The number of blades must be at least four.
The snowplow frame is assembled by welding pieces from the iron corner into the frame according to the existing scheme. All components of the frame are fastened by means of a bolted connection.
Useful advice! In rotary snow blowers, the most massive bearings should be used, which will be able to withstand the beating of the rotor mechanism.
For self-assembly of a snowplow, you can use improvised
When all the components of the snow blower are ready, proceed to assemble them into a single unit.
A screw shaft is mounted on the rotor mechanism. Then this whole mechanism is fixed on the frame using bolts and a pressure ring. The fastening of the rotor to the frame is done by means of a special bracket. As a snow thrower for a homemade rotary snow blower, a plastic pipe with a diameter of 100 mm is used.
Benefits of Combined Snow Blower Models
In comparison with screw aggregates, snowplows of combined design are most effective in operation, since the load is shared between the screw and the rotor. They have sufficient power and can cope with the cleaning of the terrain from the snow mass of an impressive size. Among the advantages of homemade rotary snow blowers, there are:
- Excellent maneuverability and superior performance technology;
- Depending on the motor used, the snow emission range can reach 12 m;
- The ability to adjust the width of the snow cover;
- The small weight of the machine (up to 20 kg) allows you to cope with the cleansing of the house area (including a woman);
The process of cleansing the local area from snow
- The possibility of repairing the snow blower with your own hands;
- Low cost in for the production of all device devices.
Independent manufacture of a rotary snow blower is a rather complicated and painstaking task.
If you are poorly versed in technology, do not have certain abilities or do not have the right tool, and you don’t have the money to buy a factory model, you can make a snow shovel with your own hands.
Snowblowers produced by recognized companies are expensive, and far from everyone can afford the purchase of similar equipment. Of course, the snow thrower in Russian weather conditions is a very necessary machine, but is it worth putting 10 thousand rubles per unit, which, in any case, will be used occasionally?
The average Russian, most likely, will prefer to remove snow on his own site with a traditional shovel, but people who have certain technical abilities can make a snow blower with their own hands without the help of others, especially since this will not cause special problems for people who are not very familiar with technology, and of the costs, perhaps, only the engine.
How to Weld a Reducer Angle Grinder To a Trimmer
In the homemade product we are considering, the creator got a small engine from the tiller, a conveyor belt (in its absence, you can also use a sidewall from a car tire), a plastic sewer pipe with a diameter of 160 mm and an aerosol can with paint.
It’s all. All other elements of the machine can be made from improvised means.
For the production of the snow blower, the choice fell on the Honda engine with a capacity of 6.5 l / s (it makes no sense to use less) with an automatic transmission and gearbox with a gear ratio of 1×2.
At medium engine speeds, the chain drive delivers about 600 rpm to the auger.
If you want to install an electric motor with an air cooling system on the snow blower, you should take care of thorough protection of the air absorber from snow.
The optimal grip width for a homemade snow blower is 50 cm. This will ensure its maneuverability and allow you to easily clear narrow garden paths without much difficulty. The total width of the machine will not exceed 65 cm, which will allow it to be stored in a garage or barn.
We describe in general terms the design needed for a homemade snow blower.
The creator made the screw housing from a sheet of roofing iron, the sidewalls from plywood 10 mm wide, the frame from an iron corner, the handles from a half-inch pipe. A pipe with a diameter of ¾ d can be used as a screw shaft. A through cut is made in the middle of the pipe, into which a 120 × 270 mm iron plate is inserted and fixed, which is designed to fold snow. When the shaft rotates, the snow mass will be shifted to the plate with a double-running auger made of a conveyor belt. Four rubber seals attached to special plates.
Plain bearings are mounted directly on the pipe.
If the pipe is wider than the diameter of the inner ring of the bearing, it can be turned. In the attached photo and drawing, special adapters are machined for mounting bearings on a lathe.
In the manufacture of the auger, a conveyor belt with a length of 1.5 m and a width of 10 mm was used. 4 rings are cut from the tape with a diameter of 28 cm. The rings are cut using a jigsaw. In its absence, the rings can also be cut with the use of the plank with 2 screws screwed into it. By rotating the board in the same way as a compass, you can get completely high-quality workpieces.
The auger rotates on closed self-centering bearings 205. To install the auger, only sealed bearings should be used, otherwise, under the influence of snow, the bearing will quickly become worthless.
The screw drive can be chain or belt.
The size of the capture housing should be two to three centimeters larger than the size of the pulley. In this case, the pulley will not touch the housing, and, at the same time, the gap between them will be small.To prevent damage to the screw, it would be nice to equip it with a safety pin that breaks when the screw is jammed.
If you already have a tiller on the farm, you can reinstall its engine in the winter on a snow blower.
In order to reinstall the motor does not require much time and the introduction of a special tool, you should install quick-detachable fasteners on the snow blower.
Among other things, this will facilitate the transportation of the snow blower, since the engine is a more languid structural element, and after dismantling it, the snow blower can be moved and serviced without stress.
Under the skis, on which the whole structure is mounted, you can adapt wood blocks with plastic pads (do not use duralumin and other iron rails for skis, the snow sticks to them and the snow blower starts to slip poorly.
Or as an option. You can screw the plastic strip).
In the final version, the creator replaced the wheels with skis
The swivel gutter designed to discharge the snow removed is made of a plastic sewer pipe with a diameter of 160 mm. A chute is attached to the pipe, which sets the direction of the snow mass. A pipe of a similar size is fixed on the auger body, on which the swivel chute is put on. It should be noted that the cross section of the chute must exceed the width of the auger plate that emits snow mass.
For effective snow removal, the hole through which the auger will throw snow must be quite huge.
In an unpleasant case, the bulk of the snow will lean forward, and not to the side, thereby reducing to zero the efficiency of the unit.
The snow blower frame is made of iron corners measuring 50 × 50 mm. Corners measuring 25 × 25 mm are welded to the transverse corners, on which a platform with a power unit is fixed. The transverse corners and the handle of the snow blower are fixed on the longitudinal corners with the help of M8 bolts.
After carefully fitting and assembling all the parts of the snow blower, it remains only to paint it, after that it will take a very walk on its own expensive company counterparts.
Homemade snow blower from a chainsaw, trimmer or motor cultivator
Snow removal with a shovel is a rather labor-intensive process.
To facilitate it, a homemade snow blower can come to the rescue. Having made it, you will not only free yourself from the hard work of clearing the snow, but also save considerable money without spending money on expensive models of units in the factory version.
Homemade Snow Blower Design Options
The main task of the snow blower is to capture and discard snow masses from the place of their accumulation, for example, from the sidewalk. Snow blowers made by craftsmen have a different design. But according to the type of snow capture, the models differ in screw and rotor models.
The main part of the snow removal unit is a screw resembling a screw from a grinder.
Screw units come in 2 types.
- Single stage.
Equipped with one screw in the form of spirally arranged knives. Spiral knives consist of 2 parts and converge in the center where the throwing blades are located. When the mechanism moves with a bucket, a layer of snow is cut, which immediately falls under the rotating knives. Extreme crush the snow and move it to the central part of the body. Since the blades are placed in the center of the auger, they capture the crushed snow and throw it into the nozzle installed in the rear of the bucket. The higher the speed of rotation of the shaft with the blades, the further snow is discarded. The auger knives can be either with a flat edge or a serrated one.
Knives with a smooth edge are used for cleaning freshly fallen snow, and are often made of conveyor belt. Toothed auger is used if it is necessary to remove icy and packed snow. Two stage. This is an upgrade of a screw type snow blower. In its design there is also a screw. But for better snow ejection, a rotor is installed in the rear of the bucket with 2 or more blades. The snow blower operates according to the same principle as a single-stage unit, but thanks to the rotor blades, the snow is better crushed and thrown out over a huge distance (up to 15 meters).
The following figure shows a two-stage type snow blower device.
The rotor-type snow blower has the simplest construction and consists of a round “snail” body and guide vanes. A sleeve is placed in the upper part of the body through which snow is thrown.
In the central part of the cochlea is installed rotor with blades. This impeller is driven by an engine (gasoline or electric). The rotor, rotating at high speeds, captures the snow, crushes it in the body of the cochlea and throws it out through the sleeve.
Snow throwers made by craftsmen for the house can be of 2 types.
- With stationary drive.
The motor is installed in the unit, after which it becomes a full-blown snow blower.
Choose engine type
Before you make a manual snow blower, you need to realize what type of motor is better to choose. Electric or gasoline.
Electrical units vary silent operation and extremely easy to maintain.
Also they do not require any consumables. The only inconvenience of electric devices is the electric cable, which constantly interferes with movement. Naturally, you can use an engine that works from rechargeable batteries, but the operating time of such a cleaner will be limited by the battery level. Therefore, if you are going to make an electric snow blower, know that he will be able to work only within the yard, that is, the range of movement of the unit will be limited by the length of the power cable.
Petrol snow cleaners are powerful and quite echoing units.
They cope with thick snow cover, including icy. Gasoline devices have an advantage over electric ones, not only in terms of power, but also in mobility, since they are independent of the electric network. Thanks to this, the units can be used for cleaning snow drifts in huge areas, for example, near the yards of the personal sector, in the yards of high-rise buildings, on sidewalks, in certain sections of the road, etc. But despite the above advantages of gasoline devices, they also have disadvantages:
- Engine service required;
- Need constant fueling;
- The presence of exhaust gases;
- High noise level during engine operation.
Focusing on the aforementioned, you can realize that if it is necessary for you to clear the yard of a cottage or small personal property from drifts, it is better to slow down on the manufacture of an electric snow blower.
If huge areas are often to be cleared of snow, then a gasoline drive can handle this task better than an electric one.
Engine options from other units
To make a snow blower with your own hands, you will need to choose an engine that will rotate either the auger or the rotor of the unit. If you are going to make a device with an electric motor, then at least some asynchronous electric motor with a power of at least 2 kW and a rotation speed of 1500 to 3000 rpm is suitable as a component of the drive. If you take the engine with the least power, it will not cope with thick layers of snow and will stop all the time. In this case, cleaning drifts with a shovel will be much more effective.
As a component of the drive, some craftsmen use engines from electric trimmers and chain saws.
You can often find homemade snowplows made from a lawn mower. But the power of these units is enough only for cleaning freshly fallen and loose snow.
A more massive version of the moving part of the drive for a snow thrower is internal combustion engine (ICE). It can be taken from a chainsaw or gas trimmer. Also, a snow removal unit can be made from a cultivator or a tiller.
The auger for the snow blower is the main moving part of the unit, the manufacture of which is not difficult. It is best to use a rubber tape from a conveyor 10 mm wide and 1.5 m long for the production of auger.
4 pieces of rings with a diameter of 28 cm should be cut out of the rubber strip. The parts are simply cut with an electric jigsaw.
Advice! To cut the rings from the tape, you can do without a jigsaw. Screw 2 sharp screws into a small plank and use this tool as a compass. After a couple of full revolutions of the torch, the ring will be cut.
Below are drawings of all parts of the auger.
As a shaft is taken metal pipe with a diameter of 27 mm. Adapters are fixed to its ends, on which bearings are installed. A cut of 120 mm in length is made in the central part of the pipe, into which a central plate will be installed, designed to discard snow.
Also 4 plates are put on and welded onto the pipe. Rubber rings will be attached to them and to the central plate. How this is done is clearly visible in the following photo.
An iron strip can also be used to produce the screw. But it is better to use rubber, since it does not scratch the paving slabs and is not damaged when it touches a hard obstacle, for example, with a curb or a fence.
Making a bucket for auger
It’s also easy to make a bucket that will serve as a housing for installing the auger.
For this purpose, traditionally roofing iron. The drawing below shows the dimensions of the bucket.
For bucket sides, you can use plywood or a piece of OSB 10 mm wide. The extreme option is more suitable for this purpose, since it is the most water-resistant than plywood. Bearings are installed on the sides of the housing (205th, closed), and the screw shaft is already inserted into them. Bearings need to be closed with glasses.
Important! When assembling the snow removal unit, you need to make a small gap, about 2 mm, between the bucket and the screw, so that the extreme does not touch the body.
To remove snow from the bucket, a hole is cut in its upper part.
As a discharge chute can be used sewer plastic pipe with a diameter of 150 mm or another. The main thing is that the cross section of the gutter exceeds the width of the auger hinged blade.
To direct the snow thrown out by a shovel to the side, you can put on the pipe plastic branch.
The bucket with a screw is mounted on a frame previously made of iron corners (50 x 50 mm) (see drawing above).
To fix the motor on it, the corners are 25 x 25 mm.
Advice! If you attach a slightly curved slide to the frame, as shown in the following figures, then it becomes much more convenient to work with a snow thrower, since it becomes possible to tilt the mechanism for a better grip of snow.
But this unit can still be slightly improved. Refinement of the snow blower is to add to the rear of the slide small wheels. In this case, the snow blower will be more convenient to pull back and transport.
Screw Blower Assembly
Snow throwers, in the base of which the auger is used, are the most massive and able to handle even icy snow.
In addition, the auger is most often used in self-propelled snowblowers.
This self-made snow blower is made quite simply. Since it will be powered by a chainsaw motor, several additional parts for a chain drive will be needed. For these purposes, you can use front and rear sprockets from the bike, as well as a chain from it.
How the frame and auger are made has been described above. A long handle is attached to the frame. A large sprocket from the bike is installed on the screw shaft on the right side, and a small asterisk on the motor shaft of the chainsaw.
Further, the chainsaw is mounted on the frame, after the chain is put on and sprocketed. To control the engine, a gas cable is displayed on a handle attached to the frame.
Below are drawings of homemade on the chassis, where a chainsaw is used as the main part of the drive.
Based on trimmer
To make a screw blower from an electric trimmer or from a lawn mowing machine, you will need to install a gearbox: it will serve to transmit rotational movement from the trimmer shaft to the screw shaft.
But there is one aspect.
A gearbox for this type of unit is quite expensive, and it is not practical to take it for the production of a console to the trimmer. Therefore, on the basis of the extreme snowblowers of the rotary type are made, which will be discussed later.
Based on a tiller
The most common addition to the tiller is blade for snow.
A homemade snow removal nozzle (shovel) on the tiller is screwed to the unit frame, after which it is converted into a small bulldozer.
Advice! Instead of a blade, a screw can be attached to the front of the tiller or motor-cultivator frame, as a result of which you get a self-propelled snowplow. This prefix for the tiller in case of need is simply disconnected from the main unit.
Below is a diagram that clearly shows the construction of a snow blower based on a cultivator.
The scheme is decrypted as follows.
- Snow blower drive connecting the engine to the auger.
- Caterpillar drive.
- Drive belt
- Roller (spurious) for reverse gear.
- Intermediate shaft.
- Roller for belt tension.
Thanks to it, the unit is moved forward.
A self-propelled snow blower greatly simplifies snow removal, especially in vast areas where the use of a ski apparatus pushed by the operator requires huge costs for the latter’s physical strength.
How to make a DIY snow blower
Winter, of course, is a magical time, especially in fair weather. A shaggy snow carpet covers the ground, gleams in the sun and. Makes it difficult to walk. In order not to be walled up in large snowdrifts and not to spend the whole day trying to overcome the snow with a shovel, snowblowers were made.
In this article for us, you will find the necessary information that will help you collect the snow blower with your own hands.
The designs are different, the result is one
Through the gearbox, the engine rotates the screw breaking the crust and rakes the crushed snow to the rotor blades, which push the snow through the outlet pipe up to 3 meters. This design is called a two-stage, as it works both a raking auger and a snow-throwing rotor.
These are quite massive machines, because those who assemble a homemade snow blower often simplify them: some have blades on the auger that themselves throw snow, albeit not as perfectly as the rotor.
Or they do it differently, leaving a single discarding rotor in the structure, and the snow comes to it thanks to the efforts of a person who rakes it with a bucket. So that for you to choose from, we have put together both options, which have already managed to prove themselves on the best side more than once, and besides, it’s enough to simply upgrade them based on what parts you have available.
about how the snow blower works
What to assemble a homemade snow blower from?
If you are firmly determined to assemble a snow blower with your own hands, first you need to choose a power unit for it.
It can be a gasoline or electric engine, or maybe a finished device, for example, a tiller.
Note that the best engine speed is up to 1500 rpm.
For the frame, iron pipes of a small diameter or a metal corner will be required.
If you want to assemble a two-stage snow blower, you will most likely need a gearbox. The easiest way to purchase it on the Internet with delivery.

Next, it is worth deciding on the type: which snow blower should be made. Auger, rotary or two-stage.
To make a rotary snow blower is best guided by drawings from an old good magazine “Modelist-constructor”.
It describes the design of the snowstorm “Blizzard”, which even a schoolchild can assemble.
A homemade rotary snow blower is structurally similar to the Blizzard. True, the masters recommend installing more than 2 blades. So the unit works more stable.
To assemble it, you need a gasoline or electric motor, a two-millimeter sheet steel for the rotor and blades on it, as well as sheets of the narrowest steel or aluminum for the snow blower body.
In this design, the engine through a chain drive rotates a shaft, at the end of which a rotor is fixed. The shaft is fixed through two pairs of bearings to avoid displacements. Almost all craftsmen use a direct drive from an electric motor, but this can lead to overheating and rebooting of the latter.

The principle of operation of the screw mechanism
To make a faithful snow blower, drawings or at least sketches are required.
Before you start developing your own project, you need to understand the structure of the snow removal mechanism.
The chamber, in which the screws are installed, moves along the hard ground with a lower cut, picking up snow in its cavity, like a bulldozer’s knife.
A rotary screw design is installed inside, which moves the snow towards the outlet. This part of the structure can be either in the center or from the 1st side of the camera. If the working width is 1 m and the most purposeful is to make a receiving hole in the center in order to more uniformly load the rotor.
In addition to helically arranged screws, the rotor is equipped with throwing blades, with the help of which snow enters the receiving hole.
Then a mechanism comes in that pushes the snow through the bell in a suitable direction, or immerses it in the body of a nearby transport.
DIY snow blower. Types of designs
The main difference is auger snow blowers, not by the method of collecting snow, but by the ability to move. Passive constructions. The operator moves this type of mechanism without the help of others; the power plant drives only the rotor itself.
This design is easy to manufacture, but you will have to make considerable efforts when cleaning snow, especially if the cover is the highest and most dense.
The snowplow is equipped with a light, low-power motor, for example, from a chainsaw. Or you can adapt the electric motor, if the cleaning area is located near the point of connection to electricity.
Sometimes a snow blower is mounted on a tiller. The power take-off shaft is only useful for you, for driving a screw mechanism. Then the tiller himself provides self-propulsion, and part of the power goes to the drive for snow removal; Self-propelled structures.
A homemade snow blower of this type is initially designed as capable of moving around without the help of others. Either drive wheels are mounted on the frame, or a tiller with its wheels is integrated into the design.
It is more difficult to create such a project, but it pays off by the ease of implementation and the least effort that you spend on snow removal; There are also snow blowers of the dump type. For work, you only need to make a semicircular blade. But this design has severe drawbacks.
Firstly, an extremely powerful motor is required for such a cleaner, since during work, a huge snow resistance acts on the blade.
Secondly, the quality of cleaning is poor.
Dense snowdrifts remain on the edge of the cleared road, which are more difficult to remove than virgin snow.
At the same time, the auger cleaner moderately scatters loosened snow over a large area without creating dense heaps.
How to make a do-it-yourself snow blower with your own hands?
First of all, we make a snow removal chamber in which the rotary screw will work. It must be barrel-shaped, with a receiving sector of at least 120 °.
It can be made from sheet steel 2 mm wide, or from aluminum sheets 3 mm wide. The corrugated aluminum used for the equipment of jeeps is unsurpassed. It is the hardest due to the molded pattern.
The most economical option is a zinc coated metal sheet.
Taking into account the low strength, it is better to make sidewalls of plywood or textolite.
Now about the most important part of the mechanism. About the screws. They can be welded from sheet steel (or the same aluminum), or they can be cut out of dense rubber from an old conveyor used in granaries or in ore management. If you can ask for old tires on tire service, good blades for the auger are obtained from the sidewalls.
Making a rotor from an iron sheet requires accuracy and painstaking layout.
Not only that, a 100 spiral must be cut completely symmetrically, the rotation step must be maintained along the entire length of the structure. Parts are welded using conductors that can be made from a pair of vices.
Throwing blades are made of the thickest alloy, since they overload the overload of already packed snow.As a result, such a design must be obtained.
Important! When developing a rotary auger, do not confuse the direction of rotation and synchronize it with the throwing blades. Correctly assembled mechanism allows you to do without an additional rotor in the outlet pipe.
The auger will have enough power to make a homemade snow blower throw snow at a sufficient distance.
The finished screw can be adapted to the tiller, mounted on wheels and moved without the help of others. Or even fasten to the frame in front of the jeep or pickup. The main thing is to provide torque to the working shaft.
Power plant for auger snow blower
If you decide to assemble a snow blower with your own hands on the basis of a tiller. The design of the drive lies on the surface. If you have a power take-off shaft, you simply output the cardan, chain or belt drive to the auger shaft, and come up with a clutch mechanism.
No need to rotate the shaft idle.
If your tiller is equipped only with a gearbox, you will need to retract the belt or chain drive to the screw from the drive axle. The gear ratio of pulleys or chain sprockets is selected in the direction of increasing revolutions.
The screw works most excellently at the highest speed, the worm principle only works on extremely dense snow. That is, the screw shaft should rotate 2-3 times faster than the wheel shaft.
If there is an additional rotor ejection mechanism on the outlet pipe, its speed must be even higher, since the size of snow in the center of the auger is largest, and it must be thrown out of the chamber as soon as possible.
Chainsaw snow blower
If there is no need to clean the driveways to the house and garage, the snowplow can be light and small.
The width of the working area is not more than 50 cm. This design is not necessarily made self-propelled, and it does not need a powerful motor. For example. From a chainsaw.
We produce a camera with a screw in the same way as in the previous version. Only we take the proper sizes. A screw for one revolution in each wing of the chamber, a secondary rotor on the outlet pipe is not needed.
Such a snow blower can move on improvised runners mounted along the edges of the chamber.
Instead of the bar, a chain drive to the rotor is fed from the chainsaw. The drive sprocket remains the same.
An additional clutch mechanism is not required, a regular friction clutch chainsaw copes with this task perfectly.
The only thing to take care of is weight distribution. Since the engine from the chainsaw is mounted on one side (in the center it is unrealistic to do this, the feed vanes interfere), the control handle must be moved from the center towards the motor mount. Then it will be more convenient to work.
The outlet pipe is made of plastic conduit.
The diameter of 120-150 mm is completely enough for that size of snow.
Such a small-sized snow blower in a few minutes will clear the tracks in your yard, and it will not take so much time to make it. And in the summer, the chainsaw is dismantled from the auger and used for its intended purpose.
All the details and secrets of making a homemade chainsaw snow blower in this. You do not even need a drawing, everything is clearly and carefully shown and explained.
