A brush cutting head having a cylindrical, tubular, support base. A plurality of cutting tooth mounting blocks are fixedly mounted on the cylindrical outer surface of the base, the blocks extending transverse to the longitudinal axis of the base, each block having a front face and sides. A cutting tooth is provided for each mounting block, each cutting tooth made from a plate having a uniform thickness with an inner surface and an outer surface. Each tooth has a straight, relatively long, base section and a straight, relatively short, cutting section bent from one end of the base section toward the inner surface to form an obtuse angle between the inner surface of the base section and the inner surface of the cutting section. Each tooth is mounted on the block with the base section of the tooth adjacent the front face of the block and the base section extending outwardly from the base, and with the cutting section above the block and extending forwardly from the base section of the tooth.
