8.11 HEADER DRAPERS
CAUTION
To avoid personal injury, before servicing
machine or opening drive covers, follow
procedures in Section 8.1 PREPARATION
FOR SERVICING.
8.11.1 Header 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. Turn bolt (A) clockwise (tighten), and the white
indicator bar (B) will move inboard in direction
of arrow (indicating that draper is tightening).
Tighten 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 draper from
scooping dirt, ensure draper is tight
enough that it does not sag below
point where cutterbar contacts the
ground.
8.11.2 Replacing Split Draper
The draper should be replaced or repaired if it
is torn, missing slats, or cracked.

reel, always engage reel props before
