214683 169 Revision A
Calibrating the Auto Header Height Control (Challenger and Massey Ferguson)
NOTE:
For best performance of the auto header height control (AHHC) system, 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 3.7.5 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.
