Brush cutter
First Claim
1. A brush cutting head having a cylindrical, tubular, support base;
- a plurality of cutting tooth mounting blocks 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, each cutting tooth made from a plate-like member having a relatively long base section and a relatively short cutting section bent from the base section;
the tooth 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.

Abstract
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.

13. A brush cutting head having a cylindrical, tubular, base;
- a plurality of cutting tooth mounting blocks fixedly mounted on the outer cylindrical surface of the base;
a cutting tooth detachably mounted on each block, each tooth having a cutting edge, the cutting edge located radially outwardly past the block; and
a protective guard 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 projecting radially outwardly from the surface a distance at least equal to the height of the block but less than the height of the cutting edge from the surface, the guard preventing the block from being struck by an object while allowing the tooth to cut when the cutting head is rotated to cut brush. - View Dependent Claims (14, 15)

23. A cutting tooth for a brush cutting head made from a plate having a uniform thickness with an inner surface and an outer surface;
- the tooth having a straight, relatively long, base section and a straight, relatively short, cutting section;
the 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. - View Dependent Claims (24, 25, 26)

27. A brush cutter having:
-
a brush cutting head having a cylindrical, tubular, support base;
a plurality of cutting tooth mounting blocks fixedly mounted on the cylindrical outer surface of the base, the blocks extending transverse to the longitudinal axis of the base and each block having a front surface;
a cutting tooth detachably mounted on each block;
each cutting tooth made from a plate-like member having a relatively long base section and a relatively short cutting section bent from the base section;
the tooth mounted on the block with the base section flush against the front face to have the base section extending outwardly from the base and the cutting section above the block and extending forwardly from the base section;
a narrow holder for the brush cutting head, the holder rotatably mounting the head at the bottom of the holder with the head aligned with the holder, and drive means on the holder for rotating the head;
and a vehicle having a boom, the holder pivotably mounted, at one end, on the end of the boom and aligned with the boom, the holder remaining aligned with the boom when pivoted relative to the boom.
