ABSTRACT:
The invention relates to a quick hitch guidance system which allows an operator to maintain proper alignment with a farm implement while towing it behind a tractor. The device includes an exterior inverted U-shaped frame with an external quick hitch coupling element. Within the frame there is attached a double rod hydraulic cylinder which operatively moves internal linkage within the frame so that the distance between the device and the tractor is increased on one side and decreased on the other thereby steering the implement into proper alignment. The implement moves independent of the tractor so that as the tractor deviates laterally from alignment with the crop rows, the position of the implement is corrected and aligned with the rows to prevent crop damage.
