The bedding spreader has an impeller rotatable inside a housing, the impeller having a plurality of vanes rotatable around a horizontal axis, in a vertical impeller plane; the housing having an inlet opening on one side of the impeller plane and being aligned with the impeller for the impeller to receive bedding through the inlet opening during use, and an outlet opening on the other side of the impeller plane, the outlet opening being spaced from the impeller, the housing forming a bedding path in which the bedding is thrusted tangentially by the impeller against a deflector arrangement made integral to the housing, the deflector arrangement thence redirecting the tangential movement of the bedding imparted by the impeller to a movement more parallel to the axis, through the outlet opening.
