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.
