The piston pump (1) drives the piston motor (8). The hydrostatic system is a closed loop. Oil is continuously pumped between the piston pump and the piston motor. The charge pump (2) provides oil to the speed sensing valve (4) which regulates the speed sensing pressure and the charge pressure. The supply oil from the charge pump is filtered by the hydraulic oil filter (7) before the oil gets to the speed sensing valve. The speed sensing valve regulates the speed sensing pressure and the charge pressure. Speed sensing pressure controls the displacement of the piston motor. The charge system provides oil for the hydrostatic system in order to replenish the oil that is lost due to leakage in the system.The piston motor is mounted to a transfer gear group (10) in order to turn the front wheels and the rear wheels. Power from the drive box is transferred to the front axle (12) through a drive shaft (11). Power from the drive box is transferred to the rear axle (12) through a drive shaft (13). The parking brake is mounted on the transfer gear group.The direction of the machine is controlled by the direction control switch that is located in the cab on the pilot valve ( joystick). The speed of the machine is controlled by the accelerator pedal. If the machine is equipped with a creeper control (5), the speed of the machine can also be controlled by the creeper control.The machine will shift to NEUTRAL, if the parking brake lever is engaged and the direction control switch is in the FORWARD position or in the REVERSE position. In order to get the machine to move, the direction control switch must be moved to NEUTRAL and the parking brake must be disengaged. Then, the direction control switch must be moved to the desired direction.
