OPERATION
6. Lower header to desired cutting height using combine
controls and check load indicator. As an example
the image shows that the wheels are set to a range
between ‘2’and‘3’onloadindicator.
Figure 4.24: Load Indicator
IMPORTANT
:
Continuou
s operation with excessive spring compression
(i.e., loa
d Indicator reading greater than ‘4’ or a
compresse
d length less than 11-5/8 in. [295 mm]) (A)
can resul
t in damage to suspension system.
7. Adjust header angle to desired working angle with the
machine’s header angle controls. If angle is not critical,
set it to mid-positio n.
NOTE:
The height sensor on the CA25 adapter must be
connected to the combine height control system in the
cab.
8. Use the windrower cab display module (CDM) controls
to automatically mainta in cutting height. Refer to your
windrower operator’s manual for details.

Cutting On the
Ground
Cutting on the ground is performed with the header fully lowered so that the cutterbar is on the ground. The orientation
of the sickle and sickle guards relative to the ground (or header angle) is controlled with the skid shoes and center-link,
and NOT with the header lift cylinders. T hese two features allow the operator to adjust to field conditions to maximize
the amount of material cut and to reduce damage to the sickle from stones and debris.
The header is equipped with a type of suspension system that floats the header over the surface to compensate for
ridges, trenches, or other variations in ground contour instead of pushing the cutterbar into the ground or leaving
uncut crop.
