The MTZ 892 tractor produced by the Minsk Tractor Plant is a modification of the legendary version MTZ 82, which has been produced since 1974. The technical characteristics of the MTZ 892 included in the design make it possible to use it not only in agriculture, but also in other industries where there is a need to use universal vehicles with increased cross-country ability.
The Belarus 892 MTZ differs from the base model in the following parameters: the presence of a turbocharged engine with an intercooler, which increases the torque of the power unit by 30%, an installed MTZ synchronized gearbox, and an increased standard size of standard tires.
MTZ 892 is a wheeled universal row crop agricultural unit with all-wheel drive, which is classified with traction class 1.4. The main purpose of Belarus 892 is to perform a large number of different agricultural works, from preparing the soil for sowing to harvesting and transport operations.
However, unlike the power-armed tractor MTZ 3022, it is not intended for cultivating large areas of land. In addition, as already noted, MTZ 892 can be used in public utilities and forestry, industry and construction.
The design of the gearbox installed on the MTZ 892 provides a multiplier (overdrive gear), which provides 18 forward gears and 4 for reverse gears. The Minsk Plant also produces a modification of the MTZ 892.2 tractor. The main technical difference between this model and the MTZ 892 is the installation of a reinforced beam-type front drive axle.
