Abstract

See full text

A steering system for a towed farm implement or wagon, such as a header transport, is provided that allows the tongue of the header transport to pivot approximately 90 degrees to the right or the left (i.e., 180 degrees in total) and translates the movement of the tongue to all of the wheels of the header transport. Front steering linkages are coupled to the tongue, and are configured to oscillate front wheels in response to rotation of the tongue. Rear steering linkages are coupled to the front steering linkages by front-to-rear linkages, and the rear steering linkages are configured to oscillate rear wheels in response to rotation of the tongue.
