Abstract
A skid steer vehicle with sprung suspensions is configured to lock the suspensions whenever the operator manipulates a manual control that generates a signal to move the loader arms or the bucket of the vehicle. The operator control, such as a joystick, sends a signal to an electronic controller indicating that the operator has moved the control and is thereby requesting the loader arms or bucket to move. The electronic controller responds to this signal by moving the loader arms or bucket and simultaneously locking the suspensions.
