ABSTRACT:
A plurality of cutter teeth (50) are mounted on outer peripheral portions of a rotary cutter wheel (22). Each tooth (50) forms a socket (74) that receives a projections (26) on the wheel (22). Opposite parallel inner socket surfaces (76) and a parallel outer surface (78) of the tooth (50) abut side surfaces (28) of the projection (26) and an edge surface (34) on the wheel (22) to snugly engage the tooth (50) on the wheel (22). The abutting surfaces (76, 28 and 78, 34) are substantially tangent to the wheel's cutting direction. A roll pin (80) may be used to further secure the tooth (50). The pin (80) fits snugly in a hole (70) in the tooth (50) and loosely in a hole (32) in the projection (26). Upper and lower tooth walls (56, 58) preferably extend along opposite surfaces of the wheel (22) beyond the projection (26).
