<p>A rotary cutter grinder that cuts and grinds upon its circumferential surface is well suited for stump grinding and the like applications. The rotary cutter grinder is constituted by a hub portion (12) for mounting to the power output shaft of a prime mover and plural (18, 20) arms unitary with the hub portion. These arms are substantially uniformly spaced about the hub portion and extend radially outwardly therefrom. A cutting tool (26), usually a tungsten carbide cutting tool, is mounted to each of the arms at a positive rake angle relative to the perpendicular to the direction of motion by the cutting tool.</p> |
