Wheel tractor MTZ 82.
History of creation
The development of a new generation of wheeled tractors with a traction class of 1.4 tons with a diesel engine began in Minsk in 1966. To speed up the process, it was decided to create a machine based on the mastered tractors of the MTZ 50 series. 75 HP The cab has also undergone modifications, the appearance of the hood and radiator lining has also changed.
Serial production started in 1974, and 6 years later the tractor underwent the first modernization with the replacement of the cab. The plant several times finalized the design of the machine, increasing the technical and environmental parameters. For example, cabs manufactured after 2021 can be equipped with air conditioning to improve the working environment for the operator. The compressor is mounted on the engine and is driven by a belt drive.

MTZ 82 engine
On Belarus cars, an in-line 4-cylinder diesel engine with forced liquid cooling is used. The early series were equipped with a D-240 engine, which had a power of 75 to 80 hp. (depending on the year of issue). The camshaft is located in the body of the cylinder block, the valves are driven by rods and rocker arms. Each cylinder has 1 inlet and outlet valve. Adjustment of gaps in the mechanism is carried out manually.
The engine of the car Belarus MTZ 82.
To start the power unit, a separate 1-cylinder starting engine with a capacity of 10 hp is used. Some tractors are equipped with an electric starter controlled from the operator's cab. Since the early 2000s an improved 81-horsepower D-243 diesel engine that meets Stage I and II toxicity standards began to be used.
Fuel is supplied by a mechanical pump and nozzles. Some units are equipped with devices for warming up before starting in winter.
Fuel consumption
Diesel fuel consumption depends on the load and the type of work performed:
- movement on unpaved and highway roads - 7 l / h;
- plowing of soil of medium density - 33.6 kg per 1 ha;
- sowing work on soils of the middle category - 14.9 kg per 1 ha;
- cultivation - 9.5 kg per 1 ha;
- plowing fire trenches - 210 kg per 100 km of ditch;
- processing of agricultural crops - 5.6 kg per 1 ha.
Fuel consumption depends on the condition of the engine piston group and on the general technical condition of the tractor and agricultural hitch. As the engine wears out, its power decreases and oil waste increases. The manufacturer recommends changing the lubricant in the diesel crankcase every 250 hours of operation (measured using a control device installed in the cab).
Transmission
The tractor is equipped with a 9-speed gearbox with a 2-speed reduction gear, which increases the number of forward gears to 18. The transmission contains 2 reverse gears, which are transformed into 4 by switching the gear. . On some tractors there is a reversible 9-speed gearbox.
Gearbox MTZ 82.
To transfer torque from the motor to the input shaft of the box, a 1-disk dry friction clutch is used. On the rear wall of the gearbox there is a power take-off shaft with a rotation speed of 540 rpm or 1000 rpm (operator selects the operating mode). An additional speed reducer is installed on some tractors, which increases the tractive effort.
Hydraulic equipment of the tractor
The hydraulic cylinders are driven by a gear pump mounted on the gearbox. The pump provides performance within 45 l / min, the pressure is limited by a safety valve. The design of the equipment uses double-acting cylinders, the permissible load capacity of the rear linkage is 900 kg (with a reach of 1900 mm relative to the axis of the rear axle). A multi-position spool valve with manual control was used to distribute liquid flows.
The engine has an additional pump with reduced performance. The assembly is used to ensure the performance of the hydraulic power steering. On equipment manufactured after 2015, a hydrostatic drive is used. The amplifier is included in the device of the steering mechanism, a steering trapezoid with levers and spherical joints is used to turn the wheels.
Pneumatic system
The pneumatic system is powered by a 1-cylinder compressor mounted on the engine. Compressed air is collected in a steel accumulator, a safety valve and a dryer are provided in the design. Compressed air is used to drive the brake chambers of the trailer and the auxiliary mechanisms of agricultural machinery.

Brake system
To stop the tractor, dry-type disc brakes are used, mounted on the axle shafts of the rear axle. 2 pedals are mounted in the cab for separate braking control, they can be connected into a common circuit (when driving on the highway). Together with the working brakes of the tractor, a pneumatic valve operates, supplying compressed air to the brake chambers of the trailer.
Electrical part of the tractor
The electrical circuit is based on a 1-wire circuit, the negative terminal of the battery and the negative terminals of consumers are connected to the tractor body. The voltage is 12 V, a lead-acid battery and a generator are installed on board. On tractors with an electric starter, there were 6-volt batteries connected to a common bank in a serial circuit.
Wheels and drive
The design of the rear axle of the tractor has a differential with a special clutch of automatic or forced blocking. The front axle is equipped with a bevel self-locking differential, a separate cardan shaft is used to drive the front axle.
MTZ 82 wheels.
At the rear, pneumatic tires with a dimension of 15.5R38 are installed (sometimes there are narrow tires 9.5R42), tires of the 11.2R20 standard are used in front. All wheels have a special tread pattern that provides increased flotation in the field.

Features and accessories
The MTZ 82 tractor allows you to perform agricultural work and is used in public utilities. On request, additional ballast weights are installed on the equipment, which increase the load on the drive wheels. In this case, normal conditions for controlling the machine are restored. In the 80s. for the tractor there was a set of rubber tracks, which was put on the rear wheels, and additional rollers. Torque transmission was carried out by lugs on the rear tires.
Through the use of additional attachments, the tractor can be used as a bulldozer or loader, it is possible to install an excavator boom and hydraulic supports to increase stability during operation. Some tractors were equipped with a side power take-off shaft, on which a pulley was attached. A belt drive from a pulley is used to drive stationary equipment (water pumps or agricultural implements).
Device
"Belarus 082" has all-wheel drive. Its design provides for disabling the rear axle, and use only the front axle for work. The tractor device provides for blocking the front axle differential and adjusting the track dimensions, which can be set with the following parameters: 600, 700 and 800 mm. "MTZ 082" is equipped with a manual gearbox, a multi-plate friction clutch is responsible for the clutch. The power take-off shaft has two modes and can operate at a speed of 1000 or 3000 rpm. The starter can be started using a battery or manually. This line of machines has a fairly compact size, but its performance is at a fairly high level. The technique is recommended to be used not only as an agricultural unit, but also as a traction tractor.

Operation features
In winter, it is recommended to warm up the engine with an autonomous heater or by supplying a stream of warm air to the engine. Do not allow the diesel engine to idle for more than 15 minutes. It is strictly forbidden to warm up the engine in enclosed spaces due to the risk of carbon monoxide poisoning. If it is not planned to use the power take-off, then the shaft control levers are moved to the neutral position.
The MTZ 82 tractor is an agricultural unit of the Minsk Tractor Plant, a universal tractor.
When synchronous operation of the power take-off shaft is activated, acceleration to speeds above 8 km/h is prohibited (due to the risk of destruction of transmission elements). The use of 9th gear is allowed only when the increased row is activated in the gearbox. The standard tractor cab is designed for the operator only. The carriage of a second person is only allowed when a passenger seat is installed (option). It is not allowed to tow equipment with a raised front axle, since increased loads destroy the axle drive gearbox.
If the equipment is operated at low temperatures, then the arctic type of diesel fuel is used for refueling. A special liquid with a low freezing point is poured into the cooling system.
After the end of the shift, the fuel tanks are filled, which reduces the risk of condensation. The manufacturer allows the operation of the tractor at altitudes up to 3000 m above sea level, to ensure high-quality operation of the motor, the performance of the fuel pump is reduced. It is not recommended to use the technique at high altitudes.
Required maintenance
The plant provides for routine maintenance of the tractor after 125, 250, 500, 1000 and 2000 hours of operation. Additionally, equipment is inspected before and after the end of the work shift. The list of works is indicated in the technical documentation supplied by the plant with the tractor. To improve the reliability of operation, seasonal maintenance is carried out, which involves the replacement of lubricating fluids in the engine and transmission units.
Main malfunctions
Tractor malfunctions are associated with difficult starting or incorrect operation of the engine due to clogged filters, wear of parts, or foreign impurities in the fuel. Damage to the radiator and pipes leads to a violation of the circulation of the coolant and overheating of the diesel engine. The tractor is equipped with a clutch, which requires adjusting the pedal free play and adjusting the position of the release levers. As the equipment is used, the gears in the transmission units wear out, which leads to an increase in noise during operation.
