A motor cultivator is a versatile technique with which you can perform many household chores. The unit is in demand even in winter for snow removal, only you need to connect the appropriate attachments to it. Now we will consider the process of making a snow blower from a cultivator with our own hands, and also find out what nozzles are still used for work in winter.
Varieties of snow plow attachments, the principle of their operation and the procedure for manufacturing
The variety of snow removal equipment for motor cultivators is not so great. The most effective is considered to be a rotary hitch. Still snow can be removed with a blade. Paired with this shovel, they usually put a road brush, but at home the latter type of hitch is rarely used.
Snow blade shovel
The simplest snowplow for a cultivator is a blade. Although, it is more reasonable to use a bulldozer with a walk-behind tractor, since it has a more powerful engine. But for a motor cultivator, you can weld a small shovel. It is very easy to work with such a hinge. The blade is attached to the bracket on the frame of the cultivator. During the movement of equipment, the shovel rakes the snow cover. In order for the snow to go to the side, and not to be piled up in a large pile, the shovel is set at a slight angle relative to the roadside.
For a motor cultivator, the blade is made of a steel sheet 3 mm thick. However, it is very difficult to bend a metal blank on your own without the appropriate equipment. It is easier to find a piece of steel pipe with a diameter of 200–300 mm, divide it lengthwise into three parts and cut out one semicircular segment with a grinder.
The bottom of the shovel is the knife. He will cut off the layer of snow. However, a steel knife can damage paving slabs or asphalt. For such work, it is necessary to cut off a strip from the conveyor belt and bolt it to the bottom of the blade.
On the back of the shovel, 2 lugs are welded at the top, and rods are attached to them, going to the control levers. Eyelets are also welded in the center of the blade. A bar is attached here, with the help of which the hitch is fixed to the bracket on the cultivator frame. The assembly of the bulldozer is over, you can try to row the snow.
Rotary snow blower
To make a rotary snow blower from a cultivator, you need to do a lot of turning and welding. Such a hitch is also called auger. The mechanism consists of a steel case. Inside, the screw rotates on bearings. The spiral blades grab the snow and push it from the sides of the hull towards the center. In this place, metal blades rotate on the rotor. They pick up the snow and push it through a nozzle mounted on the snow blower body. The direction of departure is regulated by a visor. To do this, a sleeve is put on the nozzle outlet. A swivel visor is attached to the top. The operator himself turns it in the right direction.
The most difficult part to manufacture is the auger. It is easier to find it ready-made from old agricultural equipment. Otherwise, you will have to do turning and welding work. The assembly of the screw is performed according to the presented drawing. First, a piece of pipe with a diameter of 20–25 mm is taken. Pins are attached to both ends. Knives are made of sheet steel 2 mm thick. To do this, cut out 8 halves of disks. They are welded to the pipe so that a two-sided spiral is obtained. Metal blades are welded in the center of the rotor between two spirals.
After the auger is made, they begin to assemble the snow blower body. Its fragments are cut out of a steel sheet 2 mm thick. A steel strip is attached to the lower part of the body, acting as a fixed knife. He will cut the layers of snow. To make it easier for the snow blower to move through the snow, the body is placed on skids called skis. From above, in the center of the body, a pipe is welded from a piece of pipe. This will be the outlet for the ejection of snow.
The next step is to install the auger. First, bearing seats No. 203 are bolted to the side walls of the housing from the inside. After that, the auger itself is installed. The transmission of torque from the cultivator motor to the rotor is organized using a belt drive. Here you need to install the drive and driven pulley. It is advisable to think over the tension system. It will help adjust the gear to avoid belt slippage.
A casing with a swivel visor for ejection of snow is bent out of galvanization. At the back, rods are attached to the body of the rotary snow blower, with the help of which a hitch with a motor cultivator is provided. During the operation of the mechanism, the snow from the sleeve will fly out to a distance of 3–5 m.

Fan snow blower for motor cultivator
According to the presented drawings, you can make a fan-type snow blower. First, an oval body is welded from sheet steel. This shape is needed for suction of snow by a fan. A bushing for bearings is installed in the hole in the rear of the housing. There will be 4 of them in the snow blower. Two bearings are mounted on the shaft, after which they are inserted into the sleeve. One end of the shaft must extend outside the housing. Two more bearings with a glass are mounted here, to which mounting brackets are welded. On this side, the end of the shaft should also protrude.
The rotating mechanism of the snow blower is ready. Now the fan blades are mounted on the shaft protruding inside the housing. The front of the impeller is covered with a protective steel mesh. A pulley is mounted on the outer end of the protruding shaft. A belt drive from the working shaft of the cultivator engine will fit here.
Now you need to organize a snow ejection hole. To do this, a wide hole is cut at the top of the oval housing near the fan impeller. A pipe is welded in here, and a tin sleeve with a visor is put on top. The rotating blades of the fan will draw snow into the housing and, under pressure, throw it out through the sleeve.
The disadvantage of a fan snow blower is the limited use of the hitch. The fan is capable of sucking in only freshly fallen loose snow. If the cover is caked, icy or wet, then such a snow blower will not work.
Combined snow blower for motor cultivator
Craftsmen who love to invent something special have combined a rotary and fan snow blower into one design. The result is an efficient attachment. In such a snow blower, the auger mechanism cuts off the caked and wet cover. The blades throw snow into the nozzle, where a working fan pushes it through the sleeve with air. The effectiveness of using a combined snow blower is to increase the throw distance.
In the manufacture of this attachment, the snow blower is first assembled. The outlet nozzle on the body is welded with a large diameter. Additionally, a ring is fixed here on the side, into which the rotor with fan blades is inserted. A sleeve with a swivel visor is put on top of the nozzle. The rotation of the fan and auger is organized from the cultivator engine through a belt drive. It may be necessary to put three-strand pulleys on the shafts.
Conclusion
The cost of a homemade snow blower will cost the owner many times cheaper than purchasing a factory-made hitch.
