Abstract: A hitch assembly includes a base member, an extension arm and an A-frame for supporting any of a plurality of implements. An elevating cylinder is connected to raise and lower the extension arm. Additionally, lateral cylinders are synchronized to move in unison to pivot the hitch assembly laterally side to side. The first respective ports of the lateral cylinders are directly connected together facilitate synchronous movement. A universal joint is connected between the arm and A-frame to coordinate up and down and left and right movement of the hitch assembly.
