The quantity of the controls is minimum. | | Steering Gears and Brakes | | Due to two-stage planetary steering mechanisms two gears are available: the first one is working, the second one is transport (forward and reverse) as well as the tractor turning and braking. The planetary steering gears are equipped with the planetary row comprising the system of the constant-mesh gear, locking friction clutch and two brakes. The planetary steering gear control is performed with a lever by means of the hydraulic servo drive. | | Final Drives | | Two-stage, with a pair of the spur pinions and the planetary row comprising the sun and coronary gears, spider and satellite gears with ratio 11.08. | | Traction and Speed Performance
