摘要：
A suspension system is provided for use with a crop harvesting header including a frame carrying a structure movable about an endless path to deliver a crop to the header. The frame has opposed ends and is pivotably connected to the header, each end of the frame being independently movable between a first angle between the frame and the header and a second angle between the frame and the header. A first suspension member and a second suspension member are each connected between the frame and the header to provide a substantially constant force to the frame between the first and second angles.
