The auger screw consists of an elongated axle, the axle to be mounted horizontally into the implement and to be rotatably driven, the elongated axle defining first and second opposite end portions and an intermediate portion located between the first and second end portions; first and second spiralling blades, integrally mounted to the axle first end portion and spiralling along generally parallel spiralling paths; third and fourth spiralling blades, integrally mounted to the axle second end portion and spiralling along generally parallel spiralling paths, and defining a first pitch being inverted relative to the pitch defined by the first and second spiralling blades. Any material engaging any one of the first to fourth blades will be biased toward the axle intermediate portion for discharge therefrom through a chute.
