F. DRAPER TENSION
The drapers are tensioned after installation at the
factory, so should not require adjustment.
Draper tension should be just enough to prevent
slipping, and keep draper from sagging below
cutterbar. The white bar (A) (shown in the next
column) should be about “halfway in the window”.
a. Raise header, and shut down engine. Engage
header lift props.
WARNING
Stop windrower engine, and remove key
before making adjustments to machine. A
child or even a pet could engage the drive.
CAUTION
Engage header lift cylinder stops before
working under header.
b. 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.
c. 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.
