Abstract: An adapter for mounting an implement on a tractor has a frame to which the implement is attached and which, in turn, it is connected with the vertically swingable stabilizer link of the three-point hitch of the tractor. A crossbar, connected with the two powered, vertically swingable drag links of the three-point hitch, has a pivotal connection with the frame such that they swing relatively. The extent to which the tractor may be turned without turning the implement is limited by stops on the frame engageable with the crossbar. Spring-loaded connections between the frame and the tractor drawbar orient the impelemtn as it is raised by the drag links such as to yieldably hold the implement in its normal position directly trailing the tractor.
