I have a condition where every time I engage the header clutch the corn head will raise between three to four inches.The raise/lower switch in the hydro handle is functioning normally. Another problem I had during harvest was when finishing with soybeans occassionally the auto header height module would override the switch in the handle and not allow the header to raise at the turn rows. I had to reach down and turn the auto header height knob to the off position to raise the head.After getting the machine turned around and lined up for the next pass. As soon as the header height knob was turned from the off position the head would immediately drop to its field position without any input from the hydro handle switch. Any suggestions other than the auto header height module is causing both my problems?
