This is a large rotatable cutter head primarily useful in masticating vegetation ranging from grasses to large trees. The inventive cutter head is typically mounted on an articulating arm on a tractor or tread-based vehicle. Depending upon the size of the arm and its maneuverability, the cutter head may be used to cut and grind vegetation variously from the ground surface to many feet off the ground. The rotatable cutter head assembly includes a number of rotating cutters mounted inside the periphery of the assembled drum and that spin freely outside the diameter of that drum and, upon contact with vegetation, rotate into the drum assembly. The invention includes combinations of the cutter head with the support vehicle or articulating arm and methods of using the cutter head.
