A rotor for a bagging machine used to force feed material, e.g., silage, for compaction in a tunnel of the machine prior to insertion of the material into a large storage bag. The rotor includes teeth sets closely spaced along the length of the rotor and each teeth set including at least three circumferentially spaced teeth. Preferably the teeth of each teeth set are intregal with a support or base ring that slidably fits en elongate pipe or tube and position axially in circumferentially as desired and then weld tacked to the pipe.
