A switch actuation assembly is provided with a support means for supporting the switch in a fixed position relative to orientations of a moveable member. A motion response element is operably connected to the moveable member for being moved in one of two directions in response to movement of the moveable member toward one of the orientations and for being moved in the other of the two directions in response to the movement of the moveable member toward the other of the two orientations. An actuating member is provided for engaging the switch to actuate the switch from a first position to a second position. The actuating member is in frictional contact with the motion response element whereby the actuating member is moved by the response element until any force of resistance to the movement of the actuating member exceeds the static friction force.

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.
