Abstract
A combination of a tractor hydraulic arm assembly and a hitch adapter installed between the two arms of the arm assembly, the hitch adapter consisting of a length of “U” shaped steel channel, having a plurality of holes formed in the top surface, with trailer hitches mounted in the holes and a steel shaft fastened to the underside of the channel and a yoke mounted on each end of the channel. The steel shaft is mounted in holes formed in the arm assembly and locked in place with implement clips, with the yolks straddling the two arms to prevent rotation of the channel.
