MAINTENANCE/SERVICE
DRAPERS
Draper Tension Adjustment
Draper tension should be just enough to prevent
slipping and keep draper from sagging below cutterbar.
Set draper tension as follows:
1. Check that draper guide (rubber track on under-
side of draper) is properly engaged in grooves of
both drive and idler rollers.
2. Tighten bolt (B) until white indicator bar is partially
hidden behind the roller support arm at (A).
IMPORTANT: To avoid premature failure of draper,
draper rollers and/or tightener components, do not
operate with tension set so that white bar is fully
hidden.
To prevent the draper from scooping dirt, ensure
draper is tight enough that it does not sag below
point where cutterbar contacts the ground.
Replacing Drapers
When installing drapers:
1. Ensure you have the proper length draper.
2. Adjust draper opening. See page 27.
3. Install screws (C) with heads facing center opening.
