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
Cab Display Module (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 0–1,400 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.
