MAINTENANCE
5.6 Feed Draper
5.6.1 Adjusting Feed Draper Tension
DANGER
To avoid bodily injury or death from unexpected
start-up or fall of raised machine, always stop
engine, remove key, and engage lift cylinder stops
before going under header for any reason. See
your windrower operator’s manual for instructions
for use and storage of header lift cylinder stops.
CAUTION
Stop engine, and remove key from ignition before
leaving Operator's seat for any reason. A child or
even a pet could engage an idling machine.
Feed draper tension should be just enough to prevent
slipping and keep draper from sagging below cutterbar.
Set draper tension as follows:
1. Raise header fully, stop engine, and remove key.
Engage header lift cylinder stops.
2. Check that draper guide (rubber track on underside of
draper) is properly engaged in groove of drive roller and
that idler roller is between the guides.
3. Loosen jam nut (A).
4. Hold nut (B) with a wrench and turn bolt (C) clockwise
to increase tension and counterclockwise to decrease
tension.
5. Correct tension is when retainer (D) is flush with spring
holder, and bolt (E) is free.
6. Tighten jam nut (A).
7. Perform equal adjustment on both sides of draper.
