ABSTRACT:
A row following drawn implement includes a transversely extended implement frame and an elongated hitch arm having a forward end adapted for connection to a towing vehicle and a rearward end connected to the frame for pivotal movement about an upright pivotal axis adjacent the rearward end of the hitch arm. A power source interconnects the frame and hitch arm for pivoting the hitch arm about its pivot axis. The power source is housed substantially within the confines of the frame to avoid interference with the mounting of tools and other equipment on the frame. A row follower senses transverse movement of the implement relative to a ground row being followed and is operatively associated with the power source to cause corrective steering movement of the implement frame relative to the hitch arm.
