摘要： A suspension for supporting an implement on a vehicle includes a transversely extending pivot shaft secured to a frame of the vehicle and a support link swingably mounted on the pivot shaft at one end portion. A second end portion of the support link extends therefrom in a fore-and-aft direction. Two spaced-apart, fore-and-aft extending support arms are also swingably secured to the pivot shaft at one end portion and are connected at another end portion to opposite sides of the implement. A lift member is coupled to the frame of the vehicle at a first end portion and to the support link at a second end portion for swinging the link about the pivot shaft. A lost motion coupling is provided between a midportion of each of the two support arms and the second end portion of the support link. The lost motion coupling includes a pin and an oversized sleeve for receiving the pin. One of the pin and the sleeve is fixed to the midportion of each of the support arms and the other of the pin and the sleeve is fixed to the second end portion of the support link to permit limited independent up and down movement of the support arms without requiring corresponding movement of the support link.
