PULL-TYPE WINDROWER ABSTRACT OF THE INVENTION A pull-type swather or windrower which can be used either singly or in a duplex or tandem arrangement can be adjusted from a working position to a transport position by pivot- ing the hitch through 90° and by unlocking the wheels so they turn through 90° to move the swather at right angles to its working direction. The swather is mounted on two wheels inwardly of the ends of the swather and rearwardly of the drapers with the wheel remote from the hitch movable to a position forwardly of its working position so as to lie under the drapers and to balance the centre of gra- vity so that the swather can be supported solely by the two wheels in the transport position. A rear or duplex swather can be attached to the front swather by a duplex hitch which provides steering movements of the rear swather in a direction opposite to the steering movements of the front swather so that the former properly tracks the latter in echelon relationship. The steering movements are ob- tained by a spring biassing the rear swather in one direc- tion and a flexible linkage arrangement which controls the amount of movement of the rear swather. The intermediate hitch can be latched to the front swather to take up a transport position.
