Tractor sand spreader PRK "Yaroslavich" is a municipal machine for winter maintenance of roads and sidewalks, which allows you to evenly distribute de-icing agents: dry marble and granite chips, sand-salt mixture or clean sand along sidewalks, pedestrian paths, courtyard areas, and village roads. The equipment is used with tractors of common brands MTZ and their analogues. The main distinctive features of the structures are high mobility and maneuverability, thanks to which the equipment is used in limited space and in areas of complex geometry, where previously only manual labor was used.
Sand spreaders for MTZ-82
A mounted sand spreading device is used to sprinkle roads with anti-icing agents, which are salt, sand or another variation of bulk mixtures. Attachment systems intended for spreading are mounted on the rear hitch units of the MTZ-82 tractor. This unit is attached to the power take-off shaft of the vehicle.
Using a sand spreader helps reduce the time required to clean a certain area. In terms of its functional potential, such a unit can replace several teams of workers.
The presence of a hydraulic drive allows you to select the most optimal position of the device during operation to ensure high-quality sprinkling of the road surface.
The main working element of the sand spreader is a rotating disk. During operation, reagents fall on it and are scattered over all surfaces of the road surface. The rate of sand flow can be adjusted by using a special dosing device. The operator can control this process without leaving the cabin. The dispenser itself is located in the container. A special device is mounted to it, designed for uniform dispersion.
The vehicle's hydraulic system is used to start the connected mechanism. Depending on the design features, this variation of specialized equipment may have different functional potential. In particular, the density of the topping, the width of the strip, and the type of attachment to the tractor change.
Advantages
High-quality sand spreaders for MTZ 82 tractors have the following advantages:
- high reliability;
- durability;
- availability of spare parts.
This applies to different device models, for example, EM-06, RS-822-MKU, etc. They are also extremely economical, small in size and allow you to sprinkle large sections of the road with sand or granite chips in the shortest possible time.
Today on the market you can find sand spreaders made in various countries: America, Europe, Asia, Russia.

Operating principle and device
The sand spreader for MTZ-82 is equipped with a trapezoidal hopper. It is into it that bulk substances used as reagents are loaded. This element is made of stainless steel, so it has a long service life in the most difficult conditions. Considering the rather large weight of the unit, its installation on light-duty vehicles will pose some difficulties. Moreover, they are ideal for the MTZ-82 model.
Diagram of a mounted sand spreader
Directly from the hopper, de-icing mixtures fall onto a rotating disk, which ensures the spreading of materials over the road surface. When the tractor stops, the working shaft is activated. This element ensures that the supply of the mixture is stopped, as a result of which sand does not spill out onto the road.
The lower part of the body is equipped with four stripes that determine the direction of movement of the scrapers of the upper conveyor branch. You should also pay attention to the installation of the guide sheet located on the reverse side of the bottom of the body part (on the beams). The scrapers of the lower branch of the conveyor are also installed here.
Mounted sand spreading systems are additionally equipped with a disc with blades. The latter are driven through the use of a hydraulic power unit. The unit's motor is powered from the tractor's hydraulic system. It is connected to it when using high-pressure hoses.
Main characteristics of the equipment
Manufacturing plants produce sand spreaders of various shapes. It is possible to choose a trailer or attachments. Among the main characteristics are:
- spreader working width;
- sand bunker capacity;
- sand spreader type;
- compatibility with specific equipment;
- installation method.
When choosing, you need to pay attention to these characteristics, and also take into account the overall dimensions. To spread on ordinary pedestrian sidewalks, you will need the most compact products with a small spreader width. To work on country roads, larger installations will be required.
The material of the product also plays an important role. If the sand spreader will be used in extremely unfavorable conditions, then it must be as durable and wear-resistant as possible. The cargo compartment must be sufficiently protected to withstand the negative effects of the reagents being transported. Before purchasing, you need to carefully study all the characteristics of the product.
Review of popular models
The most popular models of sand spreaders for MTZ-82 are presented below. The differences between the installations lie in the level of productivity of the installations and the width of the processing bandwidth.
PR-2.5
This model provides high-quality sprinkling of road surfaces with deicing agents. The installation is aggregated with tractors, the towing class of which is kept at the level of 1.4 tons. Among them there is also the MTZ-82 model. With a total weight of 5.5 tons, the unit can be operated at speeds of up to 25 km/h. The device is 4.4 m long, 2.5 m wide, and 2.7 m high.
Depending on the settings, the width of the working area varies between 4-9 meters. The process of filling the bunker with anti-icing reagents is carried out through the upper grid.

EM-06
The trailed sand spreader EM-06 for MTZ-82 is designed for spreading materials whose moisture level does not exceed 7%. The procedure for installing the unit on a tractor does not involve any great difficulties. This is due to the design simplicity of the device. If necessary, you can re-equip the equipment within the shortest period of time.
Without additional filling of the hopper, when using medium-density reagents, the operator can process the equivalent of 15 km of track. After this, an additional download will be required.
