Figure 5.46: Float Indicator Box
NOTE:
The ideal ground pressure
—
in most cases
—
is one
number (on float indicator box) above header
suspended off ground. For example, if float indicator
needle (A) is positioned at 0 with header suspended off
ground, then ideal ground pressure will be achieved
with needle positioned at 1. Operating with heavier
pressures can wear cutterbar wearplate prematurely.

Check that float lock linkage is on down stops
(washer [A] and nut [B] cannot be moved) at both
locations.

If header is not on down stops during next two steps,
voltage may go out of range during operation causing a
malfunction of auto header height control (AHHC)
system.
