ABSTRACT:
The hitch assembly of the invention is comprised of a horizontal member adapted to be secured to a tongue of the object to be drawn or pulled. The horizontal member has first and second spaced apart downwardly projecting elements. The first element has a cross-section suitable for engaging an opening in a drawbar of the tractor or object and the first element has a length less than the second element. A latching element is pivotally secured to the second element in an end region of the second element. The latching element has an upwardly extending arm having a portion extending transverse to the horizontal member. In addition, the latching element has a length such that the transverse portion is held by the force of gravity against the end region of the first element.
