Title: Tongue for connecting a draft implement to a towing vehicle

Abstract: A tongue for connecting a pull type implement to a towing vehicle is provided with a front end portion adapted to be detachably connected to the rear portion of a towing vehicle and a rear portion adapted to be pivotally connected to a lower front portion of the implement for movement about a substantially horizontal lateral axis, with an abutment fixedly supported by the frame and being positioned above the rear end portion of the frame, the abutment being adapted to abuttingly engage a corresponding upper front portion of the implement for limiting pivotal upward movement of the tongue relative to the implement and for permitting the abutment to swing forwardly away from the upper front portion of the implement to accommodate pivotal movement of the tongue relative to the implement incidental to downward movement of the towing vehicle relative to the implement and to unhitching of the implement.
