Abstract:
1. A hitch for coupling a towed-implement to a prime mover, said hitch comprising: a drawbar having opposing first and second ends, said first end pivotally connected to and supported by the prime mover; a hanger connectable to and supportable by the prime mover and having a laterally disposed elongate guide structure for supporting said drawbar between said first and second ends and allowing movement of said drawbar about said pivot connection; a pair of drawbar cushion modules disposed within said guide structure on opposing sides of said drawbar, each said module having a pinned member and a connected cushion member, said pinned member having a base and a pin connection structure for receiving a removable pin also inserted into the guide structure, the pinned member selectively securing said module to said hanger, said cushion member being disposed generally adjacent said drawbar whereby limited movement of said drawbar is allowed within said guide structure through deflection of said cushion members; and each said drawbar cushion module further comprises an impact member in movable relationship with said pinned member and said cushion member, said impact member being disposed between said cushion member and said drawbar and movable relative to said pinned member by compressing said cushion member and each said impact member is configured to allow a range of deflection of said cushion member wherein at a deflection limit of the range the impact member contacts the pinned member thereby preventing damage to said cushion member.
