Figure 4.137: Auto Header Height Control Console
To adjust the header height, ensure that the header is in AHHC
mode, as indicated by AUTO MODE LED light (A) displaying a
continuous, solid light. The header will lower to the height (i.e.
the ground pressure) corresponding to the position selected
with height control knob (B).
Turn knob (B) counterclockwise to decrease the ground
pressure setting and clockwise to increase the ground pressure
setting.

Figure 4.138: Float Indicator Box
NOTE:
In most cases, the ideal ground pressure is one number (on the
float indicator box) above the value at which the header is
suspended off the ground. For example, if the float indicator
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 higher
pressures can wear out the cutterbar wearplate.
