Scope of application of the MTZ-3022 tractor

The Belarus MTZ-3022 tractor is indispensable in agriculture. It is used to perform a whole range of agrotechnical operations, including sowing operations, harvesting, fodder preparation, as well as surface tillage:

Plowing with tractor MTZ-3022

plowing;
loosening;
disking;
cultivation;
harrowing.

The equipment is powerful, highly productive, and therefore capable of working on large agricultural areas. For a certain type of operation, the machine is equipped with special equipment and dual wheels for moving on soft soils.

The technical characteristics of the MTZ-3022 tractor are designed for operation in difficult conditions and with different types of soil.

Scope of application and design features of the MTZ-3022 tractor

The priority purpose of the Belarus MTZ-3022 tractors is to perform a wide range of agricultural work with a variety of trailed, mounted and semi-mounted machines and implements. “MTZ-3022” performs well when working with wide-cut soil cultivation and harvesting complexes; and also as a drive for stationary agricultural machines.

The element of this all-wheel drive tractor of the fifth traction class is large-scale field work that requires high productivity and speed; vast areas of land. Here are the agricultural works in which the MTZ-3022 tractor shows the best performance:

plowing at high speeds;
pre-sowing tillage;
deep loosening and cultivation;
sowing grain and other agricultural crops as part of combined and wide-cut units;
performing row-crop work in various row spacings;
harvesting work as part of high-performance feed procurement complexes;
harvesting grain crops;
transport and loading works.

The ability to install a creeper makes it possible to use this tractor also in road construction, and in reclamation and earthmoving work. This significantly increases the overall annual use of the tractor and the economic efficiency of its direct operation.

Working on the MTZ-3022 tractor is possible on soils with a wide variety of load-bearing abilities, thanks to a wide range of ballasting, using “various caliber” ballast loads, and (or) filling the wheels with liquid; with the possibility of installing double wheels and wheels of different radii.

The efficiency of the tractor in performing these agricultural works is ensured by the possibility of its aggregation with heavy-duty attachments, wide-cut harvesting complexes and high-performance stationary mechanisms. Including modern foreign-made technology. For example, with the Amazon sowing complex, which has a six-meter working width, and with the Disco-8500 mower produced by the Claas concern.

The tractor, adapted for long-term operation in reverse mode, is equipped with two control posts and is equipped with redundant transmission and brake modules, as well as a dual fuel supply system.

Engine device

Initially, the MTZ-3022 tractor was equipped with an American-made S40E 8.7 LTA diesel engine, 8.7 liters in volume. The power unit was distinguished by its performance characteristics, but due to its high cost they decided to abandon it.

A good alternative to it was the six-cylinder engine of the German brand “Deutz BF06M1013FC”, which is equipped with a charge air intercooler. The engine complies with the Stage II environmental standard certificate, therefore it has a reduced level of emissions of harmful substances.

The unit has the following technical characteristics:

working volume – 7.1 l;
power – 300 horsepower, or 223 kW;
maximum torque value – 1300 Nm;
crankshaft rotation speed – 2300 rpm;
volume of fuel tanks – 500 l;
oil tank capacity – 70 l;
specific fuel consumption – 249 g/kW per hour;

The motor is created using the latest technologies. It is equipped with a battery-powered fuel delivery system with electronic injection. Electro-hydraulic nozzles play an important role in this process.

Characteristics of the MTZ-3022 tractor transmission

The Belarus MTZ-3022 tractor has a hydromechanical 24-speed gearbox with constant mesh gears. The transmission unit with an additional control lever allows the tractor to move forward in 36 gears and backward in 24 modes. In this case, 6 gears are switched under load. The tractor is equipped with a friction dry double-disc clutch of a permanently closed type , with a mechanical release drive.

Control of the MTZ-3022 tractor gearbox

Steering based on a hydrostatic system allows the car to easily change direction and drive forward at a speed of 39.5 km/h and backwards at 19.39 km/h.

A beam-type front drive axle is necessary to transmit torque to the steered front wheels. It is equipped with a final drive, an automatic locking differential and wheel reduction gears. Thanks to this structure, the equipment is deprived of the ability to slip.

The MTZ-3022 tractor is equipped with multi-disc service brakes with oil cooling and hydrostatic drive. They are connected to an autonomous parking brake.

The electrical equipment of the agricultural machine depends on an alternating current generator with a power of 2000 W.
