1. A mechanism for positioning a transport wheel on an agricultural mower, the mower having a frame supporting a transversely aligned cutterbar and a draft tongue connected to the frame a pivotal about an upstanding hitch axis for pulling the mower forwardly or rearwardly along a normal travel axis, the mechanism comprising:
a moveable wheel support frame having a pivoting end and generally opposing a free end, the pivot end being connected to the frame for movement about a pivot axis between a retracted position and a deployed position, the free end having a transport wheel connected thereto; an actuator having opposing first and second ends defining a length therebetween, the length being selectively adjustable between a retracted length and an extended length, the first end being connected to the frame; and a linkage connecting the second end of the actuator to the moveable frame, the linkage causing movement of the moveable wheel support frame from the retracted position to the deployed position as the actuator length is adjusted from the retracted length to the extended length, the transport wheel being positioned generally above and rearward of the cutterbar when the support frame is in the retracted position, movement of the transport frame toward the deployed position causing the wheel to be positioned forwardly and at least partially below the cutterbar and be aligned for rotation allowing movement of the mower when the frame is rotated to align the cutterbar in parallel with the normal travel axis. |
