Revision C
6.5.8 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
CDM, and is stored in the WCM memory so that if
the header is detached and then re-attached 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 and the
operator can then pre-set the speed.
NOTE
The knife speed cannot be programmed
outside the range specified for each header.
