ABSTRACT:
A control apparatus controls movement of a lift arm and tool on a skid steer loader. Power actuators are coupled to the lift arm circuit and the tool circuit for moving the lift arm and tool along a path. A sensor is coupled to the skid steer loader for sensing a desired parameter and providing a signal indicative of the desired parameter. A power interrupter is coupled between the power actuators for the lift arm and tool and the sensor and interrupts power to the actuators based on the signal. A manually operable bypass mechanism is coupled to the power interrupter and the power actuators and is used to bypass the power interrupter to allow movement of the lift arm.
