OPERATION
4.4.2 H ead er Float
Float is inten
ded for cutting crops that require the cutterbar to be in contact with the ground. O ptimum float is
for the cutter
bar to maintain contact with the ground with minimum bouncing and scooping or pushing soil. The
machine will p
erform best with minimum extra weight on the header.
IMPORTAN T:
• To avoid frequent breakage of knife components, scooping soil, or soil build-up at cutterbar in wet conditions,
header float should be set as light as possible without causing excessive bouncing.
•Whenfloat setting is light, it may be necessary to use a slower ground speed to avoid excessive bouncing and
leaving a ragged cut.
• The stabilizer wheels are designed t o minimize bouncing at the header ends and NOT float the header. Refer
to your header operator’s manual for float setting and adjustment guidelines.
Float Oper
ating Guidelines
When working with the cutterbar on the ground:
1. Set center-link to mid-range position (05.0 on cab display module [CDM]). Refer to 4.4.5 Adjusting Header Angle,
page 124.
2. In rocky fields, adjust skid shoes down to raise guards when operating at flattest header angle to minimize
scooping rocks.
3. Adjust header height or adjust header angle to minimize pushing soil.
When working with the cutterbar off the ground (draper header only):
1. Set cen te r-lin k to m id -ran g e position (05.0 on CDM). Refer to 4.4.5 Adjusting Header Angle, page 124.
2. The proper setting requires balancing the amount of header weight carried by the float and stabilizer whe els.
Refer to your draper header operator’s manual.
3. Use the CDM controls to automatically maintain cutting height. Refer to 4.4.6 Cutting Height, page 127.
