Abstract

A control system (42) controls actuation of a hydraulic cylinder on a skid steer loader (10). The control system (42) includes a movable element (44, 45), movable by an operator. A position sensor (46, 51) is coupled to the movable element (44, 45) and provides a position signal indicative of a position of the movable element (44, 45). A controller (48) is coupled to the position sensor (46, 51) to receive the position signal and provide a control signal based on the position signal. A valve spool (52) controls flow of hydraulic fluid to the hydraulic cylinder (54). An actuator (50) is coupled to the controller (48) and the valve spool (52) and moves the valve spool (52) in response to the control signal from the controller (48).
