ABSTRACT:
A hitch assembly consists of a scissors action connectable between the clevis of a towed vehicle such as an implement or the like and between a towing vehicle such as a tractor or the like. One end of the scissors action is closed and pivotally connected to the clevis and the other end is also closed and connectable to the tractor draw bar or the like. A control plate is operatively connected between the scissors action intermediate the ends thereof and the connection to the tractor draw bar. One end of the scissors action is connected, for example, to the front aperture in the draw bar of the towing vehicle whereupon the tractor or towing vehicle is backed up relatively close to the clevis of the towed vehicle. The scissors action may then be extended and/or swung from side to side manually so that it aligns with the aperture in the clevis which may then be pinned into position. The tractor is then backed up, and stops on the control plate engage the sides of the rearwardly extending draw bar thus forcing the alignment of the clevis with the draw bar. When the scissors action is fully retracted, a spring loaded pin automatically engages through apertures in part of the scissors action, the draw bar and the control plate thus locking the hitch assembly in the towing position.
