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 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.
