A rotary plow feeder for feeding granular material downwardly through a feed aperture in the bottom of a bin, hopper or other housing in the form of an annular stream comprises a rotary scoop disposed above and close to the feed aperture, the scoop including at least one plow blade continuously and gently curved in the form of a spiral and extending essentially around the whole periphery of the feed aperture and a cover or shroud disposed above and connected to the blade. The outer end of the blade is disposed in contact with or close to the side wall of the housing, and the inner end of the blade is disposed adjacent the feed aperture at a distance therefrom sufficient to permit granular material to be moved into position around the entire periphery of the feed aperture.
