Example: A 7.6 m (25 ft.) header operating at a ground speed of 9.7 km/h (6 mph) would produce a cut area of
approximately 7.3 hectares (18 acres) in one hour.
3.7.8 Draper Speed
Correct draper speed is important for achieving a good flow of cut crop away from the cutterbar.
The draper speed is controlled with the windrower cab display module (CDM). Refer to your windrower operator’s manual
for instructions.
Adjust draper speed to optimize crop feeding for a well formed windrow. Excessive draper speed will reduce draper life.
3.7.9 Knife Speed
The header knife drive is driven by the windrower hydraulic pump and is controlled with the windrower cab display module
(CDM). The default speed is 1200 strokes per minute (spm).
Refer to your windrower operator’s manual for more information.
