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.
