ABSTRACT:
An implement side shift assembly is disclosed for laterally shifting an earth-working implement relative to a tractor or the like. The side shift assembly includes a frame assembly having laterally extending upper and lower slide rails. An implement support bracket mounts the implement to the slide rails for lateral movement. A slide plate is slidably mounted between the slide rails for lateral movement, and a piston-cylinder is connected between the frame assembly and slide plate to move the slide plate laterally. A latching mechanism mounted on the implement support bracket selectively connects the slide plate to the implement support bracket at one of a plurality of connecting points on the slide plate. One of the features of the invention resides in attaching lift cylinders to the side shift frame assembly at positions as far outboard as possible on the opposite ends of the frame assembly to reduce the bending and twisting moments on the frame induced by the implement. A further feature of the invention resides in a hose tensioning device that permits a relatively large amount of hydraulic hose for the implement control cylinders to be fed out or retracted for accommodating the movement of the side shifting implement.
