Auto Header Height Control (AHHC)
MacDon’s auto header height control (AHHC) feature works in conjunction with the AHHC option available on
certain combine models.
A sensor is installed in the
fl
oat indicator box (A) on the FM100 Float Module. This sensor sends a signal
to the combine allowing it to maintain a consistent cutting height and an optimum
fl
oat as the header follows
ground contours. A two-sensor system is also available as an optional kit.

fl
oat modules are factory-equipped for AHHC; however, before using the AHHC feature, you must do
the following:
1. Ensure that the AHHC sensor’s output voltage range is appropriate for the combine.
For more information, refer to
3.8.1 Sensor Output Voltage Range – Combine Requirements, page 101
.
2. Prepare the combine to use the AHHC feature (applies only to some combine models—refer to the instructions
for your combine).
3. Calibrate the AHHC system so that the combine can correctly interpret data from the height sensor on the
combine
fl
oat module (refer to the instructions for your combine).
NOTE:
Once calibration is complete, you are ready to use the AHHC feature in the
fi
eld. Individual combine
settings can improve AHHC performance (refer to your combine instruction manual).
