Transparent fluid converter; rotor wheels diameter 530 mm; maximum transformation ratio o=2,37; maximum efficiency factor =0,906. The fluid converter provides using the engine peak torque and permits infinitely variable control depending on driven parts load.


Transmission is designed as an entire device, planetary gearbox (PGB), matching reducer, and main gear included. PGB is fully reverse three-speed power shift transmission with hydraulically operated disc friction clutches, 540 mm in diameter.


Double reduction gear; the starting gear is external toothing gear; the second planetary gear with stopped crown gear. To provide easy replacement under field conditions, the drive sprocket is made of toothed quadrants bolted together.


Impermanently closed steering clutches and permanently closed brakes are designed as oil bath multidisk clutches. This design enables the tractor to be easily and smoothly handled. The clutches are oil cooled under the pressure and do not need additional adjustment during all service period.


Three-point semirigid suspension with bogie remote pivot pin provides high thrust-and-clutch properties, impact load reduction, and, hence, the improvement of working conditions. Track rollers, carrier rollers, and guide wheels are equipped with a self-movable seal (gasket) like "DUO-CONE" and a lubricant, which does not require to be renewed during the whole service period.
Number of track rollers: 14 (7 on each side)

One-seat cabin is based on rubber shock absorbers. The cabin is furnished with noise-reducing lining, due to large double-glazed windows, the maximum view area is possible; double glazing prevents icing. The driver spring seat can be regulated according to the driver's height and weight. Ventilation and air-heater make the work inside this cabin more comfortable. The cabin is furnished with an independent diesel air-heater. An additional independent heater and a conditioner can be supplied on special customer order.
