A row-type wheeled tractor that can be used as a basic equipment, or with trailed or attached equipment. The model belongs to class 1.4, and with its help it is possible to carry out various agricultural, transport and industrial works. The tractor differs from the "younger" version with increased engine torque, larger wheels, and a synchronized 22-speed gearbox, which is equipped with a multiplier, and the work of the Belarus 892 is effective in solving a wide range of private and production tasks.

Application area

The all-rounder model Belarus 892 is used in the following fields of activity:

• Agricultural and farm work: plowing of land, harrowing, cultivation, sowing of plants, harvesting of cereals and vegetable crops, harvesting of feed, fertilization in the soil. Work can be done with or without additional equipment.
• Construction works: cargo transportation, land cleaning, trenching, etc.
• Road works: cleaning of snow, dirt, cleaning from ice.
• Forest activity: harvesting of wood, clearing of sites, etc.

Chassis

The wheelbase with 4x4 four-wheel drive, differential lock function and portal bridge provides the tractor with increased stability and cross-country qualities: Belarus 892 overcomes strong dirt, deep snow and can cross the water crossing to a depth of 70 cm. The model has an enlarged clearance of 64.5 cm, and The presence of the front portal bridge reduces the transmission load. The risk of slip is reduced thanks to the option of automatic locking of differentials, which improves the grip of the wheels with the surface. The wheels are fitted with disc brakes, which improve handling in difficult conditions.

Engine and transmission

The tractor is equipped with a 22-speed manual gearbox with 18 front and 4 rear gears. The heart of the model is a 4-cylinder engine, whose power is 89 hp. The engine operates on a diesel engine and is equipped with a water-cooled cooling system and a gas turbine supercharger. The fuel tank of the tractor holds 130 liters of fuel. Maximum speed  Belarus 892 is 35 km / h, and the torque is 15%. The starting system of the tractor is equipped with an electric starter for 6 kW; There is also a modification, which is worth buying for work in harsh conditions: it is equipped with a device that works with flammable liquid.

Steering

One of the main features of the unit is the steering of increased sensitivity, thanks to which the management of the tractor requires minimal physical effort. Hydraulic system, equipped with a powerful pump and hydraulic cylinder, which is located in the trapezium, provides a soft and docile steering wheel. There is also a modification of Belarus 892, which is equipped with a power steering, thanks to which the work becomes even easier.

Suspension system and hydraulic system

For hinged and trailed devices, the tractor has a special hydraulic system that has 6 pins for equipment installation and a mechanical latch on the rear side. The maximum pressure rating is 200 kg per cm, and the capacity of the pumping equipment is 45 liters per minute. The tractor is equipped with a power take-off shaft with a two-speed system of work, and in expanded configurations it is supplemented with a device for controlling the depth of processing and a system for universal adjustment of the rear hinged lock.

The improved versions of Belarus 892 can be used in more severe conditions than the basic model. The tractor can be equipped with pneumatic system, reverse gear, brackets for fixing loads in front, tugs and enlarged tires.

Minsk Tractor Plant, founded in 1946, is the largest manufacturing enterprise that produces agricultural machinery. Its products are in demand not only in Eastern Europe, but also in the world. 8-10% of the world market of wheeled tractors belongs to MTZ, which implements not only machines, but also spare parts.

Today, the range of universal tractors is represented by over 60 samples. Most of them are equipped with motors of their own production. The output of the equipment varies between 9-300 hp. Among MTZ 892 machines produced, a tractor or Belarus-892 deserves special attention.

Necessary to maintain the technology in working order, maintenance carried out in accordance with the passport conditions, allows to increase the life of the tractor, reduce the number of failures, prevent the increase in operating costs and the drop in power plant power.

The driver should check the device every day, including tightening fasteners, do not allow leaks of liquid, fuel and oil, accumulation of deposits and dirt. Filter elements are changed, cleaned and refueled only after cleansing the neck, filler plugs, abutting surfaces and the filter cover. The inner surfaces of the lids and filter housings should be flushed with diesel fuel.

The first maintenance is carried out after 125 hours of operation, an additional 250 hours, the second - 500 hours, the third maintenance is carried out after the end of running in 1000 hours. Special maintenance is carried out after 2000 hours, and the general - as required. In the transition to the autumn-winter period and the spring-summer seasonal maintenance should be carried out.

Maintenance is carried out in the following sequence:

1. Check the oil level contained in the crankcase of the engine, the liquid level in the cooling system.
2. Check the condition of the tires.
3. Inspection hydrosystems  , the state of electrical cables, the engine water cooler.
4. Checking the operation of brakes, engine performance, alarms and lighting, steering.
5. Removal of condensate from the cylinder.
6. Lubrication of bearings and testing of tire pressure.
7. Drain the sludge accumulated in the fuel tanks and the filter.
8. Maintenance of battery.
9. Checking the injectors for pressure and spray quality.
10. Servicing the diesel air cleaner.
