Abstract
A large square baler is equipped with a plunger drive incorporating a flywheel configured as a fan which creates a flow of air within a housing disposed about the flywheel. A duct arrangement is coupled between the housing and a knotter table housing so that air is directed across and maintains a plurality of knotters located at the knotter table free of debris.
