Abstract

A terrain following hitch which mounts on a tractor draw bar by a pin, and which allows an implement being towed to move in three planes, independent of the tractor. The hitch includes three hinges, and a draw bar attachment tube which fits over the draw bar of a tractor, and transmits force to the walls of the draw bar, instead of into the pin and pin holes. The hitch reduces wear on implements and hitch connections.
