OPERATION
To adjust header height, ensure the header is in Auto
Header Height Control (AHHC) mode. This is indicated by
the AUTO MODE LED light (A) displaying a continuous,
solid light. The header will lower to the height (ground
pressure) corresponding to the position selected with the
height control knob (B).
Turn the knob counterclockwise for minimum ground
pressure, and clockwise for maximum ground pressure.
Figure 3.162: AHHC Console
NOTE:
The ideal ground pressure, in most cases, is one number
of separation on the AHHC from having the header
fully suspended off the ground (B) to just resting on the
ground (A).
