ABSTRACT:
A vehicle tow trailer particularly useful for farm vehicles such as tractors or combines having an underslung frame with cradles for receiving the front wheels of the vehicle. The trailer is arranged with steerable wheels which track the angular relationship of a tow bar. Light weight towing vehicles can tow heavy equipment by arranging the cradles to position the axes of rotation of the trailer supported wheels of the towed vehicle ahead of the axis of rotation of the trailer wheels thereby loading the towing vehicle through the tow bar to give it better traction. The towed vehicle is afforded an abutment bar near the center of the cradle supported wheels to prevent the overrun of the towed vehicle on the towing vehicle and to provide a means for securing the towed vehicle to the trailer as by a chain. The underslung trailer body has skids on its underbody to facilitate traversing rough terrain as where a trailer wheel falls into a hole. The frame of the body is arranged to augment the skid surfaces as a ground support. A locking mechanism for the steerable wheels comprises telescoped rod sections having one end coupled to the tow bar and the other to the abutment bar. A lock release for the steering mechanism of a loaded trailer comprises a shearpin which impedes telescopic motion between the rod sections. Abutment pads selectively securable to the abutment bar permit the trailer cradles to accommodate towed vehicles having a range of wheel diameters.
