Hydrostatic Drive Motors Description
The hydrostatic drive motors are mounted inboard of the final drive and parking brake units. The motors are
variable displacement piston motors, which can turn in either direction. The direction and rate of motor rotation
determines the direction and speed in which the machine will travel. High-pressure oil from the hydrostatic pumps
turns the drive motors. The displacement solenoid valve in the motor head controls motor speed.
