OPERATION
b. On GSL press DISPLAY SELECTOR (E) to display ##.## ##.# REEL IND, or press FAST (C) or
SLOW (D) switch.
##.## = RPM or MPH or KPH
19 , ##.# = 0.0 to 9.9.
c. Press FAST (C) or SLOW (D) until desired reel index is displayed.
Examples:
• Windrower is operating at 8 mph with HEADER INDEX ON, and set at -1.0.
Display shows: 7.0 -1.0 REEL IND
where 7.0 (8.0-1.0) is the reel speed in mph, and -1.0 is the HEADER INDEX setting.
• Windrower speed drops to 7.5 mph at same HEADER INDEX setting.
Display shows: 6.5 -1.0 REEL IND
where 6.5 (7.5-1.0) is the reel speed in mph, and -1.0 is the HEADER INDEX setting.
• Windrower is operating at 8 mph with HEADER INDEX ON, and set at 2.0.
Display shows: 10.0 2.0 REEL IND
where 10.0 (8+2.0) is the reel speed in mph, and 2.0 is the HEADER INDEX setting.
4.7.3 Knife Speed
The ideal cutting speed of the knife should be such that a clean cut is achieved. Crop types and conditions usually
influence the knife and forward speeds.
The windrower control module (WCM) reads a code from the header that determines the knife speed range and the
minimum speed when the header is first attached to the windrower.
The desired speed can be programmed on the cab display module (CDM) and is stored in the WCM memory so that
if the header is detached and then reattached to the windrower, the knife will operate at the original set-point.
If no header code is detected, the CDM displays NO HEADER, and the knife speed reverts to a range from 0–1400
strokes per minute You can then adjust the speed setting.
Refer to the header operator’s manual for the suggested knife speed for a variety of crops and conditions.
NOTE: The knife speed cannot be programmed outside the range specified for each header.
NOTE: The speed can be adjusted without shutting down the machine, although it is recommended that
the windrower be stopped to enable you to reprogram the WCM.
