Abstract

See full text

A generally horizontal forwardly opening U-shaped frame is provided including a pair of front to rear extending elongated opposite side members and a rear cross member extending and secured between the rear ends of the side members. The forward ends of the side members may be removably anchored to transversely spaced rear portions of a forward implement and an elongated front-to-rear extending draw bar is provided and pivot structure pivotally anchors the draw bar to the cross member for oscillation relative thereto about an upright axis disposed intermediate the opposite ends of said cross member and the front and rear ends of said draw bar. The front and rear ends of the draw bar project forwardly and rearwardly, respectively, of the cross member, the rear end of the draw bar may have a rear implement coupled thereto and a hydraulic cylinder is operatively connected between the front end of the draw bar and the frame for adjustably laterally shifting the draw bar front end and thus variably canting the draw bar. The pivot structure is operative to adjustably shift the axis of oscillation of the draw bar along the latter and thus lateral swinging of the rear end of the draw bar for a given extension or retraction of the hydraulic cylinder may be varied.
