Abstract
A combine harvester includes a feederhouse mounted to a chassis adapted at a front end to support a crop gathering header, a duct mounted on the feederhouse that is connected to a crop conveying passage of the feederhouse via a set of suction openings, a set of vent openings in the duct, each of the vent openings having a respective closure element movable between an open position and a closed position, and a fan arranged within the duct that can be operated in a first direction to create a suction airflow to extract dust from the crop conveying passage and discharge the dust through the duct, and in a second direction to create a blowing airflow to open the closure elements and vent air through the vent openings.
