Abstract
A combine harvester includes a dust suppressor arrangement including an air duct arrangement which is coupled between an enclosed zone, extending rearwardly from the discharge end of the feederhouse and above a transverse crop conveying arrangement, and a cleaner fan arrangement so that the fan arrangement draws dust-laden air through the duct arrangement from the zone and discharges the dust-laden air into the chaffer and sieve arrangement of the crop cleaning arrangement.
