Draper Maintenance
4.1.1
Adjusting Draper Tension
Adjust the draper tension enough to prevent slipping and eliminate sagging.
Set draper tension as follows:
1.
Check that draper guide (rubber track on underside of
draper) is properly engaged in groove of drive roller,
and that idler roller is between the guides.
2.
Turn bolt (A) clockwise (tighten).
NOTE:
The white indicator bar (B) will move to the right,
indicating the draper is tightening. Tighten until
the white indicator sits halfway within the window.
IMPORTANT:
To avoid premature failure of the draper, draper
rollers, and/or tightener components, do not
operate when the white tension indicator bar is
not visible.

Draper tracking needs to be checked when the draper is first run up otherwise damage to the draper can occur.
Refer to
4.1.3 Adjusting Draper Tracking, page 41
to adjust the tracking.

Adjusting Draper Tracking
The draper deck has one fixed drive roller and one spring-loaded idler roller. The spring loaded idler roller is
located at the same end of the deck as the draper tensioner. Both rollers can be aligned with adjuster rods to
adjust draper tracking.
DANGER
To avoid bodily injury or death from unexpected start-up or fall of raised machine, stop engine, remove
key and engage safety pin before going under machine for any reason.
If the draper is tracking incorrectly, use the following table to adjust the rollers:
