Setting the Sensitivity of the Auto Header Height Control (John Deere 70 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.
1. Press button (A) twice and the current sensitivity
setting will appear on the monitor (the lower the
reading, the lower the sensitivity).
2. Use scroll knob (B) to adjust the sensitivity setting. The
adjustment will be saved automatically.
NOTE:
If the page remains idle for a short period of
time, it will automatically return to the previous
page. Pressing the check mark button (C) also
will return the monitor to the previous page.
