Note
Axles – all-wheel drive (AWD)
Features (1) Heavy duty rear axle with self-regulating internal brakes, differential lock and on-board gearboxes.
Features (2) All-wheel drive is activated by a switch on the front console or by the brake pedal when using the all-wheel braking function. All-wheel drive can be turned on while the car is moving, under load, in any forward or reverse gear. To facilitate maintenance, the all-wheel drive system is equipped with external on-board gearboxes.
Features (3) The front axle of the all-wheel drive machine is equipped with a pendulum mount, sealed and lubricated for the entire service life, eliminating the need for daily maintenance. In addition, the axles are equipped with double-acting hydraulic steering cylinders, which provide a 52° angle of rotation and increased maneuverability of the machine.
