OPERATION
4.7.3 Knife Speed
The ideal knife cutting speed should achieve a clean cut. Crop types and conditions usually influence the knife
and forward speeds.
When the header is first attached to the windrower, the windrower control module (WCM) receives a code from the
header that determines the knife speed range and the minimum speed.
The desired speed can be programmed on the cab display module (CDM) and stored in the WCM memory so the
knife will operate at the original set-point after the header is detached and reattached to the windrower.
If no header code is detected, the CDM displays NO HEADER and the knife speed reverts to the Operator’s selection
from a range of 800–1000 strokes per minute.
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 knife speed can be adjusted without shutting down the machine, though it is recommended that the
windrower be stopped before adjusting CDM settings.
