A hitch attached to a tow vehicle includes a plate slideably engaged within a plate receiver and having a ball mounted thereon. To attach the tow vehicle to a trailer, the tow vehicle is positioned such that the plate having the ball mounted thereto is placed in the vicinity of a ball receiver attached to the trailer. The plate is then repositioned manually until the ball is positioned directly under the ball receiver and the ball receiver is lowered onto the ball. After attachment of the ball to the ball receiver, the tow vehicle reverses causing the plate to advance into the plate receiver until a retainer pin locks the plate to the plate receiver thereby preventing the plate from moving relative to the plate receiver. |
