4.19.3 Calibrating Auto Header Height Control – New Holland CR/CX Series
The auto header height control (AHHC) sensor output must be calibrated for New Holland CR and CX Series combines, or
the AHHC feature will not work properly.
To ensure the best performance of the AHHC system, perform these procedures with the center-link set to D. When the
setup and calibration procedures are complete, adjust the center-link back to the 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 the display since this document was published. Refer to the
combine operator’s manual for the most up-to-date information.
DANGER
Check to be sure all bystanders have cleared the area.
Ensure that the following conditions are met:
• The header is attached to the combine.
• The combine is on level ground and the header angle is set so that the header is parallel to the ground.
• The header is on down stops and the center-link is set to D.
• The engine is running.
