An implement has ground working tools mounted thereon moved by hydraulic motors and cylinders with each of the hydraulic motors and cylinders being adjusted through a main control valve. The main control valves are, in turn, controlled by two sets of valves, one set being pilot valves manually adjustable at an operator's station on the vehicle and the second being electrohydraulic valves controlled from a remote area by radio signals received by a radio receiver on the vehicle. Safety switches are provided on the vehicle to block transmittal of the radio signals. The vehicle has a television camera mounted externally of the vehicle cab and directed internally thereof. The camera transmits images to a television screen at a remote area.
