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.
