ABSTRACT:
A feed mixer includes a main chamber in which a rotor is located. The rotor includes at least one elongated wiper rigidly connected to a rotor bar for wiping contact with a curved wall portion of the chamber. The rotor bar is prevented from incurring any substantial pivotal movement and thereby maintains a substantially consistent and uniform angle between the wiper and the curved wall portion and wiping contact therewith. The rotor also includes a square in cross section axial center tube to which the rotor arms are connected and a circular in cross section axial drive shaft is positioned in the tube and extends the substantial length thereof. Right angle elements are positioned around the periphery of the shaft matingly engaging the inside right angle corners of the tube to lock the shaft to the tube for rotational movement therewith.
