4.
Press HEADER LOWER switch (A) on the joystick lever until
the adapter and header are fully lowered. You may need to
hold the switch for several seconds.
5.
Press HEADER RAISE switch (A) on the joystick lever. The
header should stop at about the halfway point. Continue
holding the HEADER RAISE switch, and the header will rise
until the feeder house reaches its upper limit. The AHHC
system is now calibrated.
NOTE:
If the float was set heavier to complete the ground
calibration procedure, adjust it to the recommended
operating float after the calibration is complete.

Figure 4.19: Float Indicator Box
NOTE:
The ideal ground pressure
—
in most cases
—
is one number
(on the float indicator box) above the header suspended
off the ground. For example, if the pointer is positioned
at 0 (B) with the header suspended off the ground, then
the ideal ground pressure will be achieved with the pointer
positioned at 1 (A). Operating the header with heavier
pressures can wear the cutterbar wearplate prematurely.
4.5.3
Setting Sensitivity of Auto Header Height Control
–
Case IH 2300/2500 and
5088/6088/7088
The sensitivity adjustment controls the distance the cutterbar must travel up or down before the auto header height
control (AHHC) reacts and raises or lowers the feeder house. When sensitivity is set to maximum, only small changes in
ground height are needed to cause the feeder house to raise or lower. When sensitivity is set to minimum, large changes in
ground height are needed to cause the feeder house to raise or lower.
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.
