A particle spreader system for efficiently evenly distributing particles (i.e. grain, seed, etc.) within a storage bin. The particle spreader system generally includes a manifold including a plurality of discharge openings and a lower opening, a plurality of gates attached to the manifold, wherein the gates incrementally adjust about the discharge openings and a plurality of chutes attached to the manifold, wherein the plurality of chutes extend outwardly from the plurality of discharge openings. The manifold suspendedly attaches to an inlet of a storage bin, wherein the manifold receives a mass of particles via the inlet and wherein the gates regulates a flow of the mass of particles through the discharge openings.
