determines the knife speed range and the minimum speed.
The desired speed can be programmed and stored by the windrower so the knife will operate at the original set-point after
the header is detached and reattached to the windrower.
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.
Setting Knife Speed
Set the knife speed by using the ground speed lever (GSL) and the HarvestTouch

strokes per minute (spm).
