ABSTRACT:
A horizontal guidance control system for a standard three point tractor hitch is disclosed. The system employs the use of a manual control element which actuates a pair of hydraulic cylinders contained in a pair of hydraulic adjusters. The control element causes the extension of one cylinder and the retraction of the other cylinder, thereby causing controlled horizontal movement of a pair of pull links of the tractor hitch.
