Abstract

A corn head includes a first wing segment; a center segment; and a corn head adjustment system. The corn head adjustment system includes a first fold actuator and corn head hydraulics fluidly coupled to receive a fluid from a source and to selectively direct the fluid to the first fold actuator. During a fold process, the corn head hydraulics is configured to actuate the first fold actuator in order to lift and fold the first wing segment frame relative to the center frame. During an unfold process, the corn head hydraulics is configured to actuate the first fold actuator in order to lift and unfold the first wing segment frame relative to the center frame. The corn head hydraulics includes a force relief arrangement configured such that, at a predetermined position during the fold process and the unfold process, fluid pressure to the first fold actuator is reduced.
