Принадлежит: CNH Amercia LLC

A work vehicle includes a motor associated with selectable movement of a frame by operator controls. The frame structurally carries a cab structure and a first manipulating structure associated with a first implement for performing work. The first manipulating structure is selectably movable by operator controls located in the cab structure, the cab structure including a transparent member, the transparent member in communication with a source of electrical power. In response to an interruption in communication between the transparent member and the source of electrical power, the first manipulating structure is no longer selectably movable by the operator controls, while the operator controls continuously permit selectable movement of the frame by the motor.
