Abstract: Disclosed is an apparatus for completely filling a silo from a central point at the top of the silo. Silage is dropped from a centered discharge opening in a fill tube extending from the upper margin of the silo sidewall. The fill tube is articulated intermediate its length and the innermost portion is swung sidewardly when the apex of the deposited silage reaches the discharge opening. A spreader plate is then positioned in cooperative relation with the open end of the stationary outermost portion of the fill pipe and directs the final volume of silage (necessary to fill the silo) toward the far wall area of the silo. A locking member carried by the spreader plate assures that the two sections of the fill pipe are held in longitudinal axial alignment.
