DRAPERS AND DRAPER DRIVE
Draper Tracking (continued)
To adjust drive roller position, continue as follows:
3. Release draper tension by using hand or foot to
move lever (A) over-center, toward end of
header.
CAUTION: Spring loaded over-center
action causes handle to kick back
when tension is released. To avoid
possible injury, do not hold lever when
releasing tension.
4. Mark roller bracket (B) before moving roller, to
show original position.
5. Loosen nut (C).
6. Move front of roller in or out as required (see
Steps 1 and 2) in 1/8 inch (3 mm) increments
until draper edge is parallel to cutterbar.
7. Tighten nut (C) to secure the position and apply
draper tension by rotating lever (A) toward
center of draper.
8. Once drapers are tracking parallel to cutterbar,
adjust idler roller springs (see "Draper
Tension") so that draper (D) just touches
cutterbar (E) at cutting height.
9. Check that draper edges are running parallel to
cutterbar after idler spring adjustment. Adjust
again if necessary.
