Abstract: A guidance system is disclosed 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 hitch relative to the drive axle of the tractor. Another embodiment operates with an implement that is attached with a single pull hitch. The system operates in a turn around mode for the pull hitch embodiment where the implement swings outwardly during turning to minimize the turning radius for the combination of the tractor and the implement. Another embodiment of the system for a 3-point hitch attachment causes the implement to be centered behind the tractor for a farming operation where no crops or furrows are present.
