20.7 - Drapers
20.7.1 - Side Draper Belt Tension
In wet or heavy crop conditions, additional belt
tension is required to prevent belt slippage.
Increase belt tension only when necessary as
belt life, tracking, and drive components are
affected.
Proper tension must be maintained on the draper
to prevent slipping on the drive rollers. The draper
tension is adjusted via the idler roller.
1. Engage the power unit drive with the engine
at low idle.
2.
Observe from the cab how drapers are
tensioned.
Lower the header, raise the reel and engage
cylinder locks. Shut down the engine before
exiting the cab.
3. Take note of the tension indicator position
against the spring.
4. Unlock the handle to release tension.
5. Turn the adjuster bolt until the indicator is
aligned with the washer.
6. Lock the handle and tighten the lock nut.

7. Restart the Combine and repeat the running
test. Re-adjust as necessary.
20.7.2 - Side Draper Belt Tracking
If your draper drive roller is not properly
aligned, the draper may start rubbing the side
of its channel causing improper crop flow and
equipment damage.
1. Inspect the draper for proper tracking. When
not properly tracking, the draper will pile up
against the edge of the draper channel.

2.
The drive roller must be at exactly 90
degrees to the draper frame.

3.
If adjustment is required, first release the
draper belt tension handle, then loosen the
lock nut and reposition the drive roller via
the adjustment nut. Re-engage the draper
tension handle.
