OPERATION
4.4.2
Header Float
The header
fl
oat feature allows the header to closely follow ground contours and respond quickly to sudden
changes or obstacles. The
fl
oat setting is ideal when the cutterbar is on the ground with minimal bouncing,
scooping, or pushing soil.
IMPORTANT:
• Set header
fl
oat as light as possible—without excessive bouncing—to avoid frequent breakage of knife
components, scooping soil, or soil build-up at the cutterbar in wet conditions.
• Avoid excessive bouncing (resulting is a ragged cut) by operating at a slower ground speed when the
fl
oat setting
is light.
• Readjust the
fl
oat when adding or removing optional attachments that affect the weight of the header.
• Refer to your header operator’s manual for setting
fl
oat and adjustment guidelines.
Float Operating Guidelines
When working with the cutterbar on the ground:
• Set center-link to mid-range position (05.0 on cab display module [CDM]). Refer to
4.4.5 Adjusting Header Angle,
page 203
.
• Minimize scooping rocks by adjusting the header skid shoes downward to raise guards when operating at the
fl
attest header angle.
• Adjust header height or adjust header angle to minimize pushing soil.
When working with the cutterbar off the ground (draper header only):
• Set center-link to mid-range position (05.0 on CDM). Refer to
4.4.5 Adjusting Header Angle, page 203
.
• Balance the amount of header weight carried by the
fl
oat and stabilizer wheels. Refer to your draper header
operator’s manual.
• Use the CDM controls to automatically maintain cutting height. Refer to
4.4.6 Cutting Height, page 206
.
Checking Float
M-Series windrowers are equipped with primary (coarse) and secondary (
fi
ne)
fl
oat adjustment systems. The primary
or coarse adjustment uses drawbolts to change the tension on the springs in the lift linkages. The secondary or
fi
ne
adjustment uses hydraulic cylinders to change the spring tension.
