    Abstract: A retainer (16) for use in conjunction with a cutting bit (12) wherein the cutting bit includes a shank (18) that contains a recess (20) therein. The retainer (16) includes a generally cylindrical retainer body (30) that has opposite ends (34, 36) and a central longitudinal axis (L-L). The retainer body has a generally arcuate shape that defines an arc between the opposite ends thereof. The retainer body further includes at least one ear (40) that projects in a radial outward direction. The retainer body is made from a material that has a grain direction wherein the direction of the grain runs generally parallel to the central longitudinal axis (L-L) of the retainer body (30).

    Abstract: A tool sleeve rotation limitation system for reducing the rotation of a tool sleeve within a block bore of a support block, the tool sleeve having a sleeve engagement surface and the block bore having a block engagement surface. The tool sleeve rotation limitation system comprises a rotation limitation member located between the tool sleeve and the block bore so as to engage the tool engagement surface and the sleeve engagement surface and reduce rotation of the tool sleeve within the block bore, the rotation limitation member having a member perimeter which conforms to at least one of the sleeve engagement surface and the block engagement surface. Alternatively, the tool sleeve rotation limitation system comprises a resilient rotation limitation member located between the tool sleeve and the block bore so as to frictionally engage the tool sleeve and the block bore and reduce rotation of the tool sleeve within the block bore.

    Abstract: A system for excavating and/or trenching hard and soft ground material includes a support block having a bore with a cylindrical portion and a non-cylindrical portion with flat surfaces and a cutting tool mounted in the bore, which may be a non- rotatable cutting tool having a shank with flat surfaces or a rotatable cutting tool having a shank with a cylindrical portion. The non-cylindrical portion of the bore rotatably engages the cylindrical portion of the rotatable cutting tool and the flat surfaces of the bore engage the flat surfaces of the non-rotatable cutting tool. A further embodiment includes a support block having a bore with flat surfaces along the entire length of the bore that engage the flat surfaces of the shank of the non-rotatable cutting tool and which bore receives the cylindrical portion of the shank of the rotatable cutting tool but does not restrain rotation thereof. In yet another embodiment, the support block may have two non-cylindrical portions and a single cylindrical portion, while the cutting tool may have a shank with two non-cylindrical portions and a single cylindrical portion corresponding to those within the bore of the support block.
