Abstract
Abstract An elongated opening is formed through the casing of an auger on the underside and a screen is detachably secured over the opening to screen out small weed seeds and the like. This opening is blanked off when not in use and the degree of screening is governed by the volumetric intake of the auger which is adjustable.
