Setting the Sensitivity of the Auto Header Height Control
–
John Deere 60 Series
The sensitivity adjustment controls the distance the cutterbar must travel up or down before the auto header height
control (AHHC) reacts and raises or lowers the feeder house. When the sensitivity is set to maximum, only small changes in
ground height are needed to cause the feeder house to raise or lower. When the sensitivity is set to minimum, large
changes in the ground height are needed to cause the feeder house to raise or lower.
