Abstract: A control system for a variable displacement hydraulic motor. A movable element is movable to adjust the operating displacement of hydraulic fluid through the motor. A positioning actuator moves the movable element between first and second positions to cause maximum and minimum operating displacement of the motor. A range limiting actuator positions a movable stop in a desired position, such that the movable stop interengages the movable element to cause motor displacement between the maximum and minimum operating displacements. The control system thus operates the motor in at least three modes: maximum operating displacement; minimum operating displacement; and an intermediate operating displacement.
