PROBLEM TO BE SOLVED: To provide a cutter for mowing grass that has a simple structure, can readily be exchanged with a conventional, general type hand-operating grass mower (interchangeable) and can be used almost permanently. SOLUTION: This is a cutter to be used for mowing grass having several of rotatable bush Co. (12A) each attached through a bearing bush (15) on the same circumference as that of the rotary disc (11). The edge parts of the bearing bush are clamped to the rotary disc and a stainless steel nail for driving into concrete is used in the cutter (13) to be used in the rotatable bush Co. (12A). To the position eccentric from the center (Bo) of the rotatable bush (12), is fitted the hole (12D) for attaching and holding the cutter (nail). Thus, the constituted cutter/assy (10A) can be mounted on a commercial mower, particularly constitutes safe cutter. COPYRIGHT: (C)2007,JPO&INPIT
