Abstract
A machine for reducing materials such as logs, limbs, stumps and the like into small particles. A hold down and infeed roller in combination with a conveyor feeds the materials into a rotating rotor. The rotor has cutters mounted on its periphery and is rotated in a direction to produce an upward cutting action. The rotor partially reduces the materials into smaller particles. An anvil in combination with the rotor further reduces the particles into the desired size. A grate dictates the size of the materials to be discharged from the machine.
