A dust management system for an agricultural harvester includes a perforated tube extending transversely through a feeder housing of the harvester. The perforated tube has exhaust plenums at opposite ends directing any flow towards the ground over which an agricultural harvester operates. A longitudinal drive shaft mounts axial flow fans within the exhaust plenums and a drive shaft is driven through a pulley system so that rotation of the drive shaft induces flow through the perforated tube and out of the exhaust plenum.
