Abstract: A bale shredder comprising a rotatable tub, closure means at one end of the tub, a bladed rotor having access to the interior of the tub through an aperture in said closure means, the rotor being of smaller diameter than the tub and being rotatable about an axis generally parallel to but spaced from the axis of rotation of the tub and, bale abutment means determining the degree of penetration of blades of said rotor into a bale, the bale abutment means being such that the position of said bale abutment means, in the direction of the axis of rotation of the bladed rotor, can be adjusted relative to the blade tips during operation of the shredder, to control during shredding the degree of penetration of the blade tips into a bale engaging said bale abutment means.

Abstract: A bale shredding device including a stationary platform above which is positioned a rotatable bale-receiving tube. An aperture in the platform exposes a rotor rotatable about an axis parallel to, and spaced from, the axis of rotation of the tub, and, the diameter of the rotor is substantially less than the diameter of the tub. Blades carried by the rotor co-act with a bale received by the tub to shred the material of the bale.
