AHHC System

Auto Header Height Control (AHHC) System Overview
MacDon
’
s AHHC feature works in conjunction with the AHHC option available on certain combine models.
NOTE:
This section does not apply to Versatile combines.
Sensors installed at each end of the PW8 Pick-Up Header send a signal to the combine allowing it to maintain a
consistent cutting height as the header follows ground contours.
PW8 Pick-Up Headers are factory-equipped for AHHC; however, before using AHHC feature, you must do the
following:
1.
Ensure that AHHC sensor
’
s output voltage range is appropriate for combine. For more information, refer to
4.1.3 Height Sensor Output Voltage Range
Combine Requirements, page 102
2.
Prepare combine to use AHHC feature.
3.
Calibrate AHHC system so that combine can correctly interpret data from height sensors on header. Once
calibration is complete, you are ready to use AHHC feature in the field. For each combine, certain operation
settings can be used to improve performance of AHHC feature.
NOTE:
If your PW8 Pick-Up Header is not equipped to work with a specific combine model, you will need to install
appropriate combine completion package. Completion packages come with instructions for installing height
sensors.
Refer to the following instructions for your specific combine model:
