A bale shredder apparatus may comprise a bale hopper defining a bale chamber configured to receive a bale to be shredded and including a perimeter formed of walls with a bale feed opening formed in the perimeter and a floor positioned toward a bottom of the bale chamber. A bale shredding assembly may include a shredding rotor having a plurality of flails positioned with respect to the bale chamber to contact a bale in the bale chamber through the bale feed opening. The apparatus may include a bale flipping assembly configured to engage a bale positioned in the bale chamber of the bale hopper and flip an orientation of the bale with respect to the hopper. Optionally, the apparatus may include a primary bale movement assembly positioned toward the chamber bottom to move a bale in the bale chamber toward the shredding rotor of the bale shredding assembly.
