The first snow brings not only joy, but also worries. A layer of snow that is not removed in time makes it difficult for people and cars to move. In the spring, snowdrifts can turn into water and flood the territory. Often, the shovel is powerless before removing snow debris; a snow-removing walk-behind tractor comes to the rescue.
Classification of motoblock snow blowers
Snow removal from large areas is carried out using specialized municipal equipment. But in a tight space there is no place for large machines: tractors (MTZ) and snow blowers (Honda). The problem is solved by using a walk-behind tractor equipped with snow plows.
The walk-behind tractor is a versatile agricultural machine equipped with a hinged auger rotor mechanism. The principle of operation is to collect the snow mass, pass it through a special impeller and throw it aside. The technique is intended for cleaning small areas with loose snow. In order to remove snow in a short time and with maximum efficiency, special snow removal devices have been developed.
Types of snow blowers for walk-behind tractor:
- bulldozer - acts with the help of a blade-blade;
- screw (one-stage);
- rotary screw (combined, two-stage).
There are 3 types of snow plows:
- blade-shovel;
- brush;
- screw-rotor attachment.
Attachment methods
Attachments are made for specific models of walk-behind tractors. Depending on the design characteristics of the walk-behind tractor and the different location of the power take-off shaft, there are several possibilities for attaching the attachment:
- directly, it is used only for models with a built-in gearbox with the required gear ratio;
- by means of a hitch;
- using a belt drive;
- through the gearbox.
Varieties of motoblock snow plows
A snow plow is an attachment, a prefabricated welded structure attached to a walk-behind tractor. There are several options for choosing a snow plow attachment for a walk-behind tractor.
Shovel blade for walk-behind tractor
Note!The blade-blade is intended for throwing snow, covers an area of 1 m.
The working speed of the unit with a nozzle is from 2 to 7 km / h. The lower edge is protected with a rubber band to prevent damage to the road and sidewalk surfaces. Rubber also protects the cutting edge from wear.
The hinged blade can be fixed at different heights, change the position in the horizontal plane. The shovel is attached to the walk-behind tractor using the front of the universal hitch.A snow shovel for a walk-behind tractor should be used on a heavy walk-behind tractor, since lighter models will allow gaps in clearing due to their low weight.
Snow brush
It can be used to clean the area from fresh snow, the layer of which does not exceed 30 cm. The surface must be flat and large. A rigid snow blower brush is mounted on a rotating shaft. The coverage area is 1 m. The height and coverage angle (from 25 degrees) is adjustable in different directions and forward. The device is used where the coating cannot be damaged.
The snow blower rotary nozzle shows the highest performance. The design of the auger rotor device consists of a paddle wheel and an auger that captures the snow and moves it up. The wheel lifts the snow mass, throwing it through the funnel at a distance of 5-15 m. The snow blower is used when there is a large amount of snow.
The principle of operation of snow removal equipment
The design of a snow plow motoblock consists of several elements:
- engine;
- front blades that pick up snow;
- rotor assembly inside the mechanism.
The description of the mechanism of action begins with the motor. The motor drives the screw auger with knives, acting on the principle of a meat grinder. When the auger rotates, the ahead-lying snow is crushed with the help of notches cutting into it and the mass moves to the center. The rotor blades pick up the snow and send it to the hull solo. After that, the snow is pushed out through the outlet pipe at a distance of several meters. This is a two-stage design typical of finished units.
The rotary model combines the functions of a snow blower rotor and auger. The twisting screw feeds the snow mass into a wide mouth with a large rotor. The torque of the rotating rotor accelerates the movement of the snow. A powerful jet of snow can fly off at a distance of 20 m.
The auger snow blower is one-stage. The snow mass from the conveyor moves directly into the blowing funnel. A powerful jet of air throws the snow out.
Motoblock manufacturers
Buying snow removal equipment is often accompanied by a dilemma: buy a snow blower or a snow plow attachment for a walk-behind tractor?
As winter approaches, the buyer has a choice of which snow-removing walk-behind tractor to buy for the country. There is an extensive assortment of varieties of snow removal equipment, among which the most popular models stand out:
- Megaladon-06 to the "Salute" walk-behind tractor is represented by a rotary snow-removal attachment.
- Sm-06 acts on the "Cascade" walk-behind tractor thanks to the rotating augers.
- The snow plow for the "Mole" walk-behind tractor is a one-stage snow blower that throws snow at a distance of up to 5 m.
- Snow blower auger rotor motor-block "Belarus" 05-09N-MTZ SN-1M.
Snow removal equipment for a walk-behind tractor is sold in Moscow in a wide range. For example, the daewoo dast snow blower comes in electric, battery and gasoline models. You can purchase snow plow attachments for motor-blocks Oka, Salyut (Agat), Ugra, MTZ Belarus, Agros, Krot.
How to make a snow blower from a walk-behind tractor
Before you take on the independent manufacture of a snow blower, you need to sensibly assess your skills, since the task will require effort. At the heart of the most common homemade product is the Neva, Honda walk-behind tractor. The attachment can be made in three versions:
- The nozzle, like a bulldozer, is attached to the walk-behind tractor using a special adapter. The layer of snow is cut off with a knife - a metal sheet with a sharp edge.
- There is a more complex way that requires a drawing. Design - a rotary nozzle consisting of a box, auger and a pipe that ejects snow. This is the most efficient two-stage system.
- Another tricky way is to make a fan blower. With the necessary skills and time, a fan is made, the blades of which scoop up the snow and throw it through the pipe.
You can make a snow blower for a walk-behind tractor from scrap materials. To make a snow shovel for a walk-behind tractor, tools are needed: a tape measure, a drill, a grinder, a welding machine. You will need an unnecessary large diameter pipe or barrel.
Cut out the dump of the desired depth from 2 halves of the barrel, you can use a curved sheet of metal with a thickness of 2 mm or more. They are scalded with a rigid frame, internal struts are made to ensure rigidity. A steel semicircle with three holes is welded to adjust the direction of rotation. Attachment to the walk-behind tractor is made of a rod and brackets, the holder is fixed in the center of the blade.
You can take an old auger from any technique. The auger is made from a pipe, with holders on the sides. The working part is made of metal blades of the same size, between which equal gaps are left.
To make a screw auger, 8 large and 4 slightly smaller discs are cut out of metal sheets. They are put on the shaft. It is necessary to monitor the rigidity of fastening structural parts, counting on intensive use. The rotor is made from an aluminum boiler with a volume of 20 liters. Rivets (4 mm) are used for fixation on the front wall of the auger.
A snow plow in the form of a pipe with a socket is welded in the central upper part of the box. The work is carried out using the rotating shaft of the cultivator. To transmit torque, adapters are required, for example, a flexible belt hitch (A-100 belt).
The purchase of mounted snow removal equipment makes the walk-behind tractor a universal assistant in the farm. It is better to buy in specialized stores with guaranteed product quality.
