Abstract
A header for a combine harvester includes gauge wheels which can be converted from a normal gauge position to a transport position in which the header is wholly supported by the gauge wheels and towed longitudinally of its length. One of the gauge wheels is a single wheel which moves inwardly toward the centre of gravity in the transport position. The other of the wheels is a walking beam system in the working position and forms a transverse axle in the transport position. Each of the gauge wheels is mounted upon a bracket which can pivot about a horizontal axis from a raised spring biased gauge position to a vertically depending position allowing rotation of the wheel about a vertical axis on the bracket. The header therefore can be transported without the necessity for a separate trailer system.
