Abstract
An apparatus for positioning a pull type farm implement has an elongated tongue being drawn by a motor vehicle having a vehicle hitch on the rear end thereof configured for attachment to the tongue, the apparatus including a hydraulic hitch mechanism configured to have one end portion attached to the vehicle hitch and an opposite end portion configured to be attached to the tongue of the implement in a non-pivoting manner, the hitch mechanism having at least one hydraulic cylinder for selectively adjusting the lateral position of the front end of the tongue. An optional GPS is operable to detect the position of the tool bar relative to the desired path and repeatedly generate position signals and apparatus for controlling the hydraulic hitch mechanism to adjust the lateral position of the tongue so that the implement follows the desired path of movement in response to the GPS signals.
