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
Header Angle in the header operator
’
s manual.
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.
