The aperture defined by the closure and the hook includes a lower circular open portion, the center point of the lower circular portion lying on a first horizontal plane substantially bisecting the pattern of attachment of the hitch, the first horizontal plane lying below a second horizontal plane projected tangent to the under surface of the ball, the rearmost point within the aperture defined by the pintle hook and the closure in closed position to receive and hold the lunette, lying the furthest rearward from the vertical plane of the attachment plate, lies within the lower circular portion of the aperture in a horizontal plane passing through the center of the attachment pattern, whereby during towing, the load of the trailer attached by the lunette is evenly distributed over the pattern of attachment.
