Abstract
A hitch for connecting the tongue of a towed vehicle to a drawbar on a towing vehicle is manually operated from the cab of the towing vehicle. The drawbar is of the double-tongue type that receives the trailer tongue between two drawbar arms. A draw pin is maintained on an arm below drawbar and pivots upwardly to couple the drawbar and tongue. The operating mechanism includes a manual actuator in the cab and a mechanical or hydraulic power transmission joining the actuator to the pin setting or pulling mechanism.
