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.

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.

If the screen remains idle for a short period of time, it

will automatically return to the previous screen.

Pressing the check mark button (C) also will return the

monitor to the previous screen.
