Patent ID: 7490678

Claim:
Apparatus for positioning a farm implement of the type which has an elongated transverse tool bar to travel along a desired path of movement while being drawn by a motor vehicle moving generally along the path, the vehicle having a mounting hitch on the rear end thereof, said apparatus comprising: hitch means for attachment to the hitch of the vehicle and configured to have the implement mounted thereto, said hitch means having hydraulic means for selectively adjusting the orientation of said hitch means relative to the mounting hitch, the tool bar being operatively attached to said hitch means; a global positioning system (GPS), said GPS including a receiver and an antenna, said antenna being mounted near or forwardly of the tool bar, said GPS being operable to detect the position of the tool bar relative to the desired path as the vehicle moves forwardly generally along the desired path and generate a signal that is indicative of said lateral position means for controlling said hydraulic means to adjust the orientation of said hitch means so that the implement follows the desired path of movement in response to said signals from said global positioning system receiver.
