Revision A
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 in the header operator
’
s manual for instructions.
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.
