Abstract
Abstract An implement hitch arrangement comprising a fore carriage extension on the implement connected to a turntable above the rear axle of the tractor whereby the implement is supported at its front end on the tractor. The implement is drawn by a conventional draw bar, so that the weight of the implement is not taken by the draw bar, but by the fore carriage extension.
