5088/6088/7088
For best performance of the auto header height control (AHHC) system, perform the ground calibration with the center-link
adjusted as long as possible. When the calibration is complete, adjust the center-link back to desired header angle. For
instructions, refer to 3.7.4 Header Angle, page 78.
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.
To calibrate the AHHC system, follow these steps:
1. Set the float on the header and the adapter (refer to the operator’s manual for instructions). Position the fore-aft and
the center-link in midspan.
