1. An apparatus comprising a hitch for coupling a ground working tool with a work machine, the hitch including:
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 comprising
a clevis including a first clevis member including a first eye and a second clevis member including 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 oblong-shaped third eye, the clevis and the tang member being rotatable relative to one another about a Z-axis of the pin, and the clevis being tiltable relative to the tang member in a Y-Z plane extending along a centerline of the oblong-shaped third eye;
wherein the play-added clevis joint comprises a seating member positioned intermediate the first clevis member and the second clevis member and having a seating face facing the tang member, a first planar surface of the seating face contacting a second planar surface of the tang member with the tang member positioned intermediate the first elongate member and the second elongate member to align the first elongate member and the second elongate member when the clevis is tilted to a predetermined degree relative to the tang member in the Y-Z plane.
