SECTION 8. MAINTENANCE AND SERVICING
Form 169441 109 Revision B
8.8 DRAPERS
CAUTION
To avoid personal injury, before servicing
machine or opening drive covers, follow
procedures in Section 8.1 PREPARATION
FOR SERVICING.
8.8.1 DRAPER TENSION ADJUSTMENT
Draper tension should be just enough to prevent
slipping and keep draper from sagging below
cutterbar.
Set draper tension as follows:
a. Check that draper guide (rubber track on under-
side of draper) is properly engaged in groove of
drive roller, and that idler roller is between the
guides.
b. If required, set draper tension as follows:
1. Turn bolt (B) clockwise (tighten) and white
indicator bar (A) will move “inboard” in
direction of arrow to indicate that draper is
tightening.
2. Turn bolt (B) counter clockwise (loosen) and
white indicator bar (A) will move “outboard” in
direction of arrow to indicate that draper is
loosening.
3. Adjust until bar is about “halfway” in window.
IMPORTANT
To avoid premature failure of draper,
draper rollers and/or tightener
components, do not operate with
tension set so that white bar is not
visible.
Also to prevent the draper from
scooping dirt, ensure draper is tight
enough that it does not sag below
point where cutterbar contacts the
ground.
