ABSTRACT:
A guidance system for the combination of a farm tractor and trailing implement, wherein the guidance system is of the type where the implement is attached to a 3-point hitch mechanism that can be angularly oriented in a horizontal plane by extending one side relative to the other to change the angle of the cross bar relative to the drive axle of the tractor. An alternate embodiment operates with an implement that is attached with a single pull hitch. The system includes circuitry which provides for warning of improper operation and delay means for sounding a warning, provides correction of the position of the implement without over-shooting or hunting by the system. The system utilizes Hall effect sensors for determining the angular position of a wand and or either the implement tool bar or the hitch that is attached to the 3-point hitch of the tractor.
