Cutterbar off ground (draper header only)
The optimum float setting and stabilizer wheel setting lets the header cut the crop evenly with minimal bouncing. Proceed
as follows:
1. Set center-link to mid-range position (5.0 on the Harvest
Performance Tracker [HPT]). Refer to
Header Angle, page 192.
2. Set cutting height with header height controls on the GSL.
Refer to 4.6.5 Setting Cutting Height, page
3. Press rotary scroll knob (A) on HPT to display the
QuickMenu system.
4. Rotate scroll knob (A) to highlight header float icon (B) and
press scroll knob to select.
5. Turn scroll knob (A) to highlight left (B) or right (C) float and
press knob (A) to activate selection.
6. Turn scroll knob (A) to adjust float setting and press knob
when finished.
IMPORTANT:
Float adjustments of 1.0 (out of 10) change the header
weight at the cutterbar by approximately 91 kg (200 lb.).
Adjust float in increments of 0.05 to optimize field
performance.
7. Float is now set.
8. Use soft key 3 (D) to remove/resume float and deck
position to previous setting for the attached header.
