Abstract
A self-propelled windrower having a crop cutting header mounted forwardly thereof by a pair of laterally spaced lower suspension links and an upper centrally located stabilizing link, is provided with lifting linkages including upper lift arms mounted on the frame and lifting links interconnecting the lift arms and the lower suspension links wherein the upper lift arms are actuated by hydraulic cylinders connected hydraulically in a master-slave relationship, the rod end of the cylinders being connected to the lift arms through axially acting lost motion connections. Stops are provided to limit the upward motion of the lift arms at the transport position thereby rendering the lost motion connections ineffective.
