Calibrating The Auto Header Height Control (John Deere S And T Series) - MacDon FlexDraper FD1 Series Operator's Manual

Calibrating the Auto Header Height Control (John Deere S and T Series)

For best performance of the auto header height control (AHHC), perform these procedures with the center-link set
to D. When setup and calibration are complete, adjust the center-link back to desired header angle. Refer to
Header Angle, page 81.
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.
NOTE:
If header float is set too light, it can prevent calibration of AHHC. You may need to set the float heavier for
calibration procedure so header doesn't separate from the float module.
1. Ensure center-link is set to D.
2. Rest header on down stops and unlock float.
3. Place wings in locked position.
4. Press the DIAGNOSTIC icon (A) on the main screen of
the monitor. The CALIBRATION screen appears.
5. Select THRESHING CLEARANCE (A) and a list of
calibration options appears.
