height position. A beep will con
fi rm the setting.

MODE position (A) or (B).
5. To change one of the memorized header height set
points while the combine is in use, use the HEADER
HEIGHT AND HEADER LATERAL FLOTATION rocker
switch (C) (slow up/down) to raise or lower header to
the desired value. Press the AUTOMATIC HEADER

NOTE:
The ideal ground pressure—in most cases—is one
number (on the
fl oat indicator box) above the header
suspended off the ground. For example, if the fl oat
indicator needle (A) is positioned at 0 with the header
suspended off the ground, then the ideal ground
pressure will be achieved with the needle positioned
at 1. Operating with heavier pressures can wear the
cutterbar wearplates prematurely.
