Abstract
Automatic steering mechanism for use on apparatus for forming raised beds or ridges and furrows and lowered beds with uniform spacing with the apparatus being of a type comprising a self-propelled vehicle having a steering apparatus for steering the vehicle and a ground engaging implement carried by the vehicle for forming a guiding surface, such as provided by a ridge or furrow in the ground along the path of travel of the vehicle as the vehicle moves. The steering mechanism comprises a framework adapted to be secured to the vehicle. In one form, it also comprises a boom structure mounted on the framework for pivotal movement about a horizontal axis extending longitudinally of the vehicle; and an arm, pivotally mounted on the outer extremity of the boom structure for pivotal movement. A follower carried by the arm follows the guide surface formed in the ground. An electrical circuit is provided responsive to movement of said arm from its generally vertical position to control the movement of a steering assembly whereby movement of said arm causes operation of the steering assembly to automatically steer the vehicle in accordance with the movement of the follower. In another arrangement, the follower and arm are arranged so that the follower always trails its connection to the frame.
