A control system controls actuation of a hydraulic cylinder on a skid steer loader. The control system includes a movable element, movable by an operator. A position sensor is coupled to the movable element and provides a position signal indicative of a position of the movable element. A controller is coupled to the position sensor to receive the position signal and provide a control signal based on the position signal. A valve spool controls flow of hydraulic fluid to the hydraulic cylinder. An actuator is coupled to the controller and the valve spool and moves the valve spool in response to the control signal from the controller.

[ What is claimed is:] [1.] A control system for controlling actuation of a hydraulic cylinder on a skid steer loader, the control system comprising:a movable element;a position sensor coupled to the movable element and providing a movable element position signal indicative of a position of the movable element;a controller, coupled to the position sensor to receive the movable element position signal, providing a control signal based on the movable element position signal;a valve spool controlling flow of hydraulic fluid to the hydraulic cylinder;an actuator coupled to the controller and the valve spool, the actuator moving the valve spool in response to the control signal from the controller; andwherein the controller is configured to determine an initial position of the movable element, upon power-up, and provide a signal to inhibit actuation of the hydraulic cylinder until the movable element is placed in a neutral position for a desired predetermined time period after power-up.
