1. Apparatus for spreading material, the apparatus comprising:

  • an elongated container (10) for the material extending from an upstream end (12) to a downstream end (14) and defining a longitudinally extending central axis (20),a dispensing outlet (21) from the container (10) being located adjacent the downstream end (14) thereof,a dispensing rotor (30,100,110) mounted in the container (10) adjacent the downstream end (14) defining a main rotational axis (20), the main rotational axis (20) extending parallel to the central axis (20) of the container (10), the dispensing rotor (30, 100,

         110) being rotatable about the main rotatable axis (20) for dispensing material from the container (10) through the dispensing outlet (21), anda separating means (75,76,111) mounted on the dispensing rotor (30,100,110) for separating material for dispensing by the dispensing rotor (30,100,110) from the mass of material in the container (10), the separating means (75,76,111) being rotatably mounted on the dispensing rotor (30,100,110) about a secondary rotational axis (94,95), and being rotatable relative to the dispensing rotor (30,100,110) for ripping and separating the material for dispensing from the mass of material.
