摘要： An automatic header control for a harvester platform that conveys the sensed ground contour to the valve without distortion and can be adjusted for various heights without introducing distortions. A bar that is oscillated by the ground sensing fingers has a chain that warps and unwraps around the bar. The chain is connected through a flexible cable to a control arm that engages the control valve stem. The control valve is pivotally adjustable about the arm axis to thus provide height adjustment without distortion.
