Setting the Sensitivity of the Auto Header Height Control (New Holland CR/CX 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.
NOTE:
Changes may have been made to the combine controls or display since this document was published. Refer to the
combine operator’s manual for updates.
