4.6.7 Knife Speeds
The windrower
’
s knife speed should be set that so that the crop is cut cleanly. The Operator should choose a knife speed
which suits the type of crop being cut and the operating conditions.
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.
However, the Operator can configure their own speed setting in the cab display module (CDM). This setting will be stored
in the WCM
’
s memory, so that the knife will operate at the new setting each time 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, which
will be a value which can range from 800 to 1000 strokes per minute.
Refer to the header operator
’
s manual for the suggested knife speed for different crops and cutting conditions.
NOTE:
The knife speed cannot be programmed outside the range specified for each model of header.
NOTE:
The knife speed can be adjusted without shutting down the windrower; however, the windrower should be stopped before
adjusting CDM settings.
Refer to the following table for the minimum and maximum knife speed settings on various types of draper header.
