OPERATION
3.12.6 Draper Belt Tension
The pick-up draper belts are set at the factory, but the draper tension should be checked before operating.
NOTE: There should be visible sag in the underside of the draper.
NOTE: Draper tension only needs to be set to prevent slippage.
NOTE: Drapers may be sticky when new. Talcum or baby powder applied to the drapers should help to
reduce the stickiness.
NOTE: Drapers may need to be looser than normal for the first few hours during break-in.
Checking Draper Belt Tension
DANGER
Stop engine and remove key from ignition before leaving operator’s seat for any reason. A child or even
a pet could engage an idling machine.
1. Raise the header fully, and engage the combine lift
cylinder stops.
2. Stop engine and remove key from ignition.
3. There should be 1.0 in. (25 mm) of sag (C). When the
draper is properly tensioned, it should be visible in the
slot (B) in the deck frame, and lined up with the notch
as shown.
NOTE: Ensure draper tension is the same for left and right
side for optimum draper tracking.
4. If the tension requires adjusting, refer to Section
Adjusting Draper Belt Tension on Front Deck, page
