Choosing a snow blower for the "Neva" walk-behind tractor

Motoblocks of the "Neva" brand are extremely demanded by owners of individual farms. Reliable machinery is practiced for almost all types of agricultural work. In winter, the unit can be converted into a snow blower (snow thrower, snow blower), which will help you very quickly cope with cleaning the area from snowdrifts. To do this, you need to mount a canopy with your own hands or purchase it in a store. Depending on the modification, factory snow blowers for motor vehicles "Neva" vary in size and productivity.

Structurally modifications of snowplows for the Neva unit are identical, differing from each other only in size and technical parameters.

All mounted snow throwers are equipped with an iron body, open from the front. The housing contains a screw conveyor (auger, screw conveyor). A snow outlet is located at the top of the body. On the side of the housing, a screw conveyor drive device is mounted. And on the back side of the body, the trailing mechanism is localized.

Now about the structure in more detail. The body is made of sheet iron. In the side walls of the housing there are bearings of the screw conveyor shaft. Below on these walls are small skis to simplify the movement of this equipment on the snow.

On the left side there is a cover of the drive unit. The device itself is chain. The drive sprocket (drive wheel) is located in the upper part and is mated by means of a shaft to the drive friction wheel. The driven wheel of the drive is located in the lower area on the shaft of the screw conveyor.

For individual snow throwers, the drive and driven wheels of the drive are replaceable, which makes it possible to change the rotation speed of the auger conveyor at the snow blower. Next to the body there is a drive belt tensioner, which includes an iron bar, which is fixed to the drive casing with one edge

At the other end is a friction wheel (pulley). The tensioning bar is not rigidly fixed and can move. The snow thrower itself is actuated from the friction wheel of the crankshaft of the unit by means of a belt drive.

The screw conveyor includes a shaft on which there are two spiral steel strips with the direction of the turns towards the middle. In the center of the shaft there is a wide strip that captures and ejects snow masses through the snow removal.

The snow deflector (sleeve) is also made of sheet steel. On top of it there is a canopy that regulates the angle of discharge of snow masses. The snow thrower is attached to the rod located at the front of the walk-behind tractor.

Snow blowers are one of the options for trailed equipment for this motor vehicle. The manufacturer has developed several modifications of snow throwers. All samples of devices for removing snow masses for the "Neva" walk-behind tractor are auger structures with the discharge of snow masses from the side (side discharge). The most popular types of this trailed equipment are considered to be several modifications.

Many people believe that this is what snow throwers are called. In fact, "MB2" is a walk-behind tractor brand. The snowplow is used as a nozzle. "MB2" goes for other motor vehicles "Neva".The structure of the compact packing is elementary. The body of the iron body contains a screw conveyor. Welded spiral strips are used as knives. The discharge of the snow mass to the side is carried out by means of a sleeve (snow deflector). The sweep of the capture of the snow layer is equal to 70 centimeters with a thickness of 20 centimeters. The throw distance is 8 meters. The weight of the device is no more than 55 kilograms.

It differs from "MB2" by the device of the screw conveyor. Here it is made in the form of a set of blades, similar to the fan wheels assembled in a pile. The toothed screw conveyor handles hard snow and ice crust effortlessly. In terms of size, this unit is more compact than the "MB2" brand, but its productivity has not decreased from this.

The discharge of the snow mass is also carried out by means of a snow deflector to the side at a distance of up to 5 meters. The range of capture of the snow layer is 56 centimeters, and its maximum thickness is 17 centimeters. The mass of the device is at most 55 kilograms. When working with a snow thrower, the Neva unit moves at a speed of 2-4 km / h.

These snow-clearing sheds differ in the structure of the working device. The SMB-1 brand is equipped with a screw conveyor with a spiral strip. The capture span is 70 centimeters, the height of the snow cover is 20 centimeters. The discharge of the snow mass through the snow deflector is carried out at a distance of 5 meters. The weight of the device is 60 kilograms.

The SMB-1M attachment is equipped with a toothed screw conveyor. The gripping span is 66 centimeters and the height is 25 centimeters. The discharge of the snow mass through the sleeve is also carried out at a distance of 5 meters. Equipment weight - 42 kilograms.

When choosing a snow thrower, you should pay attention to the material for making the working area. It must be at least three millimeters thick steel.

Now let's move on to the rest of the parameters.

1. Height and width of capture. If a complete cleaning of the site is not provided, but only the opportunity to make a path in the snowdrifts from the gate to the garage, from the house to ancillary structures, most of the products sold will do. Most often, you can find a capture span of 50-70 centimeters. In most cases, the technique is capable of functioning in snowdrifts 15-20 centimeters deep, there are devices for 50-centimeter snowdrifts.
2. Snow deflector. The removed snow mass is removed by means of a snow removal device. To what extent it will be comfortable to clean the snow masses with a walk-behind tractor depends, by and large, on the characteristics of the snow thrower pipe. The snow throw distance and the pivot angle of the snow plow are important. Snow throwers are capable of throwing snow from 5 to 15 meters at an angle of 90-95 degrees to the side, relative to the direction of travel.
3. Rotation speed of the screw conveyor. Individual snow throwers have the ability to change the rotation speed of the auger conveyor by adjusting the chain mechanism. This is practical when working with snowdrifts of varying heights and densities.
4. The actual speed of the machine. The bulk of snow removal equipment moves at a speed of 2-4 km / h, and this is enough. Clearing snow masses with a walk-behind tractor at a speed of 5-7 km / h is uncomfortable, since the worker gets into the epicenter of the "snow cyclone", the visibility decreases.

The method of mounting the Neva snow plow is quite simple.

To hitch a snow shovel with a walk-behind tractor, a number of sequential operations are required:

1. remove the docking flange on the snow cleaning equipment;
2. use two bolts to couple the snowplow attachment and the unit;
3. after that, it is necessary to attach the hitch to the clamp located on the snow cleaning equipment, and fix it with two bolts;
4. remove the side protection on the power take-off shaft (PTO) and install the drive belt;
5. put protection in place;
6. adjust the tension using a specialized handle;
7. start using the equipment.

Working with the snow thrower is quite simple, if you carefully study the manual, which reflects the basic aspects, potential malfunctions and how to eliminate them. They function at low speeds, which makes it possible to freely direct the device along the required line of motion.

The manufacturer recommends not to disregard a number of useful tips.

1. The chain tension must be adjusted every 5 hours of operation. To do this, we turn off the engine and perform tension with the adjusting bolt provided in the complete set.
2. After purchasing a new snow thrower, it is necessary to carry out a preparatory audit. To do this, we run the unit for 30 minutes and try to clean the snow.
3. After this time has elapsed, it is necessary to turn off the engine, checking all fasteners for reliability. If necessary, we tighten or tighten loosely connected components.
4. At high subzero temperatures (less than -20 ° C), a synthetic oil must be used to fill the fuel tank.

Following these guidelines can extend the life of your attachment for many years without sacrificing performance. At the same time, it is possible to clean not only the precipitation that fell the day before, but also the rolled crusts of the cover. Nevertheless, for such purposes it is necessary to choose mechanisms with a very powerful screw conveyor.

Every year we receive evidence that it is very difficult to do without the use of modern technological developments, especially in rural conditions. The same can be said about snow throwers, which are true helpers for every owner, who faces the question of clearing snow masses from year to year.
