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 for a brush cutting head. The cutting tooth is 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. A plurality of the cutting teeth are mounted on a brush cutting head with each tooth mounted on a mounting block which in turn is mounted on a cylindrical support base. The cutting section of each tooth extends above the block. A protective guard is associated with each block, the guard mounted on the cylindrical surface of the base in front of the block and extending forwardly from the block in a circumferential direction about a portion of the base. Each guard projects radially outwardly from the surface a distance at least equal to the height of the block but less than the height of the cutting esection. The guard prevents the block from being struck by an object while allowing the tooth to cut when the cutting head is rotated to cut brush.
