Abstract
A hitch for coupling a ground working tool with a work machine comprises a first elongate member configured to couple with a work machine at a rearward location of the work machine, a second elongate member configured to couple with the ground working tool, and a play-added clevis joint coupling the first elongate member and the second elongate member. The play-added clevis joint comprises a clevis including a first clevis member having a first eye and a second clevis member having a second eye, a tang member including an oblong-shaped third eye, and a pin passing through the first eye, the second eye, and the third eye. The clevis and the tang member are rotatable relative to one another about a Z-axis of the pin. The clevis is tiltable relative to the tang member in a Y-Z plane extending along a centerline of the oblong-shaped third eye.
