When the header is first attached to the windrower, the Harvest Performance Tracker (HPT) receives a code from the
header that determines the knife speed range and the minimum speed.
The desired speed can be programmed and stored in the HPT 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.
