The machine disclosed is for shredding a cylindrical hay-bale. The bale (34) is rotated about its cylindrical axis (36), and is engaged tangentially by a rotary cutter (38) with centrifugal blades (52). The bale is rotated, not by the usual conveyor or drive belt but by discrete rollers. The machine has three rollers (43) on the leading side of the cutter, and one roller (45) on the trailing side. The rollers are provided with bale-engaging teeth (72,76). The leading rollers and the cutter are positioned underneath the bale, for gravity-assisted engagement with the bale. The rotary cutter has shredder-blades (52) presented edge-on to the hay, which keeps the shredding forces low; hence, the rollers can be allowed to jam-feed the bale into the cutter, which keeps the bale moving even if the bale should contain e.g. a lump of ice.
