Abstract
A cutting tool mounting assembly adapted for receiving a cutting tool includes a base having a bottom portion and a front portion that defines a receptacle having an inner wall and a bushing configured for receipt in the receptacle of the base. The bushing includes: a forward face defining an aperture for receiving the cutting tool; a shoulder generally opposite the forward face, the shoulder configured for cooperating with the front portion of the base; and a shank portion extending rearward from the shoulder, the shank portion having an outer surface configured for cooperating with the inner wall of the receptacle. A first elastomeric layer is positioned between the shoulder of the bushing and the front portion of the base and a second elastomeric layer is positioned between the outer surface of the shank portion and the inner wall of the receptacle.
