Abstract

A harvested crop remains output apparatus for a combine can alternate between a broad distribution operating mode and an ejection elbow operating mode. The harvested crop remains output apparatus includes a housing having a first opening and a second opening; a flap associated with the first opening of the housing; a flap associated with the second opening of the housing; an output conveyor for tangentially conveying harvested crop remains arranged in the housing; a broad distribution arrangement arranged downstream of the first opening; an ejection elbow arranged downstream of the second opening; and a plurality of selection devices for selectively conveying harvested crop remains to the broad distribution arrangement or the ejection elbow. The plurality of selection devices include a first flap associated with the first opening and a second flap associated with the second opening. During the broad distribution operating mode the first flap is opened and the second flap is closed, and during the ejection elbow operating mode the second flap is opened and the first flap is closed.
