  • Patent number: 6945553
    Abstract: The pressure hitch is operable from the cab of a towing vehicle. The towing vehicle is equipped with a basic ball hitch and a vertically orientable hydraulically operated ram having a rubber pressure stub at its lowermost end in an orientation above the basic ball hitch. The towed vehicle has an inverted cup-shaped socket for coupling (without need for grip tightening) on the basic ball hitch. The ram's rubber pressure stub is vertically movable for pressing against the upper outer surface of the socket and is the sole structure for holding the socket and basic ball hitch together during towing operations. The ideal towing vehicle is a front end loader.

  • Patent number: 6604752
    Abstract: The hitch attachment has a base plate with a toe-heel receiver for the attachment carrier of a front end loader on one face side and a hydraulically operable hitch on the other face side. The hydraulically operable hitch has a draw bar extending out from the base plate with a hitching opening at its outer end. A boom mounted to the upper edge of the base plate projects angularly upward to an elevated location above the hitch opening of the draw bar, and a hydraulic ram assembly equipped with a hitching pin is removably suspended from the outer end of the boom. A mid-level assembly has a circumscribing bracing structure that holds the hydraulic ram assembly in stable condition for the entry of the hitching pin into the hitching opening of the draw bar. A removable link in the circumscribing bracing structure facilitates easy removal of the hydraulic ram assembly for replacement.
