摘要：
A float cylinder and accumulator are coupled between a header main frame andan attachmentframe. The float cylinder is orientated so that its mechanical advantage inapplying a floatforce to the header varies with the position of the main frame relative to theattachment frame.Similarly, the pressure exerted by the cylinder varies inversely with itsmechanical advantage.
