THE STUMP GRINDING MACHINE MACHINE WE USE IS A RAYCO RG 20 HD

The machine removes tree stumps by the repeated gradual sweeping of a multi-toothed high speed rotating cutting wheel. The cutting wheel has teeth on it's side, in a strategic pattern. The rotating cutting wheel takes a sweep from one side of the tree stump to the other, each tooth rapidly tearing and stripping away small pieces of stump on each pass. After each sweep the cutting wheel is advanced deeper into the stump. This procedure is continuously repeated, under the precise control of the operator until the stump is satisfactorily removed.
