4.6.7 Draper Speed

Draper speed affects the orientation of stalks in the windrow. Faster draper speeds tend to form herringbone or
dovetail configurations. Refer to your header operator's manual for guidelines on what speed to use.
The draper speed can be set with switches on the cab display module (CDM) relative to the ground speed of the
windrower with the HEADER INDEX function or can run independently.

Draper to Ground Speed

Setting the speed of the draper relative to ground speed using the HEADER INDEX function allows you to run the
engine at lower rpm while maintaining the desired ground and draper speed. Reducing engine speed saves fuel
and reduces noise in the cab.
This mode requires setting the MINIMUM DRAPER SPEED and setting the DRAPER INDEX.
