ABSTRACT:
An apparatus controls operation of a power machine which has a frame, a seat supported by the frame, wheels supporting the frame, a drive mechanism for driving the wheels, a lift arm structure manipulated by power actuators, and a power circuit for controlling the actuators. An occupancy sensor is coupled to the power machine for providing an occupancy signal indicative of occupancy in the seat. A traction lockout mechanism locks the drive mechanism to preclude the drive mechanism from driving the wheels. A controller is coupled to the occupancy sensor, the traction lockout device and the power lockout device and controls the traction lockout device and power lockout device based upon the input from the occupancy sensor. A display is coupled to the controller for displaying the indicia indicative of an operational state based on a display output signal provided by the controller.
