  • Patent number: 4431207
    Abstract: An automatic hitch device for use on a tractor with a three-point hitch is disclosed. The device allows a tractor operator to engage or disengage a tow vehicle without leaving the tractor. Two fail-safe mechanisms are disclosed which prevent inadvertent disengagement of the tow vehicle. Structure for transmitting the towing load to the tractor drawbar is described. A hydraulic cylinder is used to operate a hitch pin. An alignment spring which helps direct the hitch pin into the tow vehicle hitch also relieves lateral force on the hydraulic cylinder. Co-operation between the fail-safe mechanisms and manual disengagement of the fail-safe mechanisms are also described.
