Automatic guidance system for towed farm implements

摘要

An apparatus and method for automatically swinging a center pivot, towed implement from one side to the other side of a farm machine. The apparatus includes a Global Positioning System for locating the farm machine and sensors and remote controls for various functions of the machine to check and change the status of each machine function. An on-board computer uses the sensors and the GPS and a previously installed program to automatically determine what portion of the field has been worked and to direct the farm machine to swing the implement from one side to the other as required.
