Calibrating the Auto Header Height Control (New Holland CR/CX 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. For
instructions, 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:
For New Holland CR models 6.80, 6.90, 7.90, 8.90, 9.90, and 10.90, refer to 3.8.16 New Holland Combines (CR
Series—Model Year 2015 and Later), page 271.
CAUTION
Check to be sure all bystanders have cleared the area.
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.
Check the following conditions before starting the header calibration procedure:
• The header is attached to the combine.
• The combine is on level ground, with the header level to the ground.
• The header is on down stops, and the center-link is set to D.
• The engine is running.

• No faults have been received from the Header Height Controller (HHC) module.
• Header/feeder is disengaged.
• Lateral float buttons are NOT pressed.
• ESC key is NOT pressed.
