Abstract: A locking assembly for a three-point hitch quick coupler includes a locking plate configured to be movably coupled to a main support of the three-point hitch quick coupler. The locking plate is configured to block removal of a lower hitch pin from a lower hook of the three-point hitch quick coupler while the locking plate is in a closed position, and the locking plate is configured to enable removal of the lower hitch pin from the lower hook while the locking plate is in an open position. The locking assembly also includes an actuator coupled to the locking plate and configured to be coupled to the main support of the three-point hitch quick coupler. The actuator is configured to drive the locking plate to move between the open and closed positions.

Abstract: A quick coupler for a three-point hitch includes a first main support having an implement-facing surface. The quick coupler includes a second main support having an implement-facing surface. The quick coupler also includes a cross-beam extending between the first main support and the second main support, in which the cross-beam has an implement-facing surface. The quick coupler includes a first rib extending along the implement-facing surface of the first main support and along the implement-facing surface of the cross-beam. A portion of an outer surface of the first rib is positioned inward from an outer surface of the first main support. Furthermore, the quick coupler includes a second rib extending along the implement-facing surface of the second main support and along the implement-facing surface of the cross-beam. A portion of an outer surface of the second rib is positioned inward from an outer surface of the second main support.

Abstract: A quick coupler for a three-point hitch includes a cross-beam configured to extend between a first main support and a second main support. The cross-beam is configured to support an anti-rotation hook. In addition, the cross-beam includes a top member extending along a length of the cross-beam and a bottom member extending along the length of the cross-beam. The top member and the bottom member are spaced apart to form a hollow portion between the top member and the bottom member. Furthermore, the cross-beam includes at least one cross-member extending from the bottom member to the top member within the hollow portion.
