To make your header’s auto header height control (AHHC) system compatible with New Holland CR Series combines of
model year 2015 and later (6.80, 6.90, 7.90, 8.90, 9.90, and 10.90), you must check the height sensor voltage range, engage
and calibrate the AHHC system, and adjust the sensitivity, cutting height presets, and tilt functions.
4.20.1 Engaging Auto Header Height Control – New Holland CR Series
Set these initial configuration options on your New Holland CR Series combine (model year 2015 or later) when setting up
the auto header height control (AHHC) system.

setup and calibration procedures are complete, adjust the center-link back to the desired header angle. For instructions,
refer to Adjusting Header Angle from Combine, page 78.
