Calibrating the Auto Header Height Control – Case IH Combines with Version 28.00 or Higher Software
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. For instructions, refer to the
header operator’s manual.
WARNING
Clear the area of other persons, pets etc. Keep children away from machinery. Walk around the machine to be sure no
one is under, on, or close to it.
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 header center-link is set to D.
2. Raise header on down stops and unlock float.
