IMPORTANT:
Do NOT adjust nut (C). This nut is used for draper
alignment only.
8. Turn adjuster bolt (A) counterclockwise to loosen the
draper. White indicator bar (B) will move outboard in the
direction of arrow (D) to indicate that the draper is
loosening. Loosen the draper until the white indicator bar is
at the halfway point in the window.
9. Turn adjuster bolt (A) clockwise to tighten the draper.
White indicator bar (B) will move inboard in the direction of
arrow (E) to indicate that the draper is tightening. Tighten
the draper until the white indicator bar is at the halfway
point, on the right side of the window.
IMPORTANT:
• To avoid premature failure of the draper, draper rollers,
and/or tightener components, do NOT operate with the
tension set so the white bar is not visible.
• To prevent scooping dirt, ensure the draper is tight
enough that it does not sag below the point where the
cutterbar contacts the ground.
5.7.4 Adjusting Side Draper Tracking
The side draper tracking is adjusted by aligning the drive and idler draper rollers.
CAUTION
To avoid personal injury, before servicing machine or opening drive covers, refer to 5.1 Preparing Machine for
Servicing, page 119.
Each draper deck has a fixed drive roller (A) and a spring-loaded idler roller (B) that can be aligned using the adjuster rods
so the draper tracks properly on the rollers.
