Abstract
A pull-type crop engaging machine such as a rotary mower comprises a frame mounted on transversely spaced field ground wheels for movement with a hitch arm extending to a tractor and a transport assembly attached behind the frame for moving downwardly to a transport position so that in the transport position the hitch arm extends from one end of the frame generally in the transverse direction for towing the machine in the transverse direction. The transport includes a transport ground wheel which acts to raise the frame to pass underneath the crop engaging system to support the machine on the wheel, on a second wheel behind the frame and on the hitch. The movement of the hitch and the wheel is connected and started at a position of the hitch so that the machine remains balanced. A shield behind the frame includes a portion which moves with the transport wheel.
