The spreader assembly is located below the central fill opening in the roof of a circular grain or storage bin for evenly distributing the grain over the floor area of the bin. Grain is directed downwardly into a rotatable funnel shaped hopper, the bottom end of which is rigidly secured to the upper end of a downwardly inclined longitudinally adjustable distributor member provided on the top surface thereof with side by side longitudinally extended trough means of progressively decreasing length and width from one side of the distributor member to the opposite side thereof. On reaching the lower ends of the trough means the downwardly moving grain is deflected toward the opposite side of the distributor member for discharge into the bin. The grain deflecting action rotates the funnel member and distributor member as a unit at a speed of rotation which is in direct response to the volume rate of material being supplied to the hopper member.
