COMBINE HARVESTER STRAW HOOD ABSTRACT OF THE DISCLOSURE A combine harvester having a rotary perforated air screen and a device operable to suck air inwardly through the air screen is disclosed wherein the rotary air screen is mounted adjacent a generally horizontal surface of the machine and is provided with a stationary impervious member in the vicinity of the generally horizontal surface to render the air screen imperforate at that location and hence allow foreign matter to fall from the air screen. An aperture is formed in the generally horizontal surface generally downstream of the rearward edge of the impervious member, as seen in the direction of rotation of the air screen. Foreign matter from the air screen and/or from remote sources which generally collect on the horizontal surface can be moved along the horizontal surface by the operation of the rotating air screen and deflected through the aperture for discharge from the combine harvester.
