A gravity-feed spreader for particulate matter may include a rotor. The spreader may be operable for gravity-feed operation with the longitudinal axis of the rotor in a horizontal position. A generally cylindrical rotor housing with a pair of closed, axial ends may be coaxial with the rotor. Entrance and exit apertures for the particulate matter may be formed in the surface of the rotor housing between the closed, axial ends. A rotor driver may be coupled to the rotor shaft for rotating the rotor. An intake housing may include a passageway therethrough for the particulate matter. A gate may be provided for selectively opening and closing the particulate matter passageway in the intake housing. An agitator may be coupled to the rotor shaft for facilitating movement of particulate matter through the passageway in the intake housing.
