Abstract
A header transport steering system is provided that allows the tongue of the header transport to pivot 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. Walking tandem beams are connected to the frame and are configured to rotate in height with respect to the frame.
