10.13 HEADER DRAPERS
CAUTION
To avoid personal injury, before servicing
machine or opening drive covers, follow
procedures in Section 10.1 PREPARATION
FOR SERVICING.
10.13.1 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.
10.13.2 Replacing Split Draper
The draper should be replaced or repaired if it is
torn, missing slats, or cracked.

always engage reel props before going under

stop engine, remove key, and engage lift
cylinder locks before going under machine for
any reason.
