    摘要: Disclosed herein is a cutting blade (100) for a mowing ap­paratus, which comprises a pair of first and second pivotal cutting wheels (100U, 100L) slidably superposed with each other and each provided with a number of grass cutting ed­ges (11a, 11b) along its circumference, each of the cutting teeth (CT) having a major surface (10), two side edges (11a, 11b) and an ou­ter periphery edge (12); and mechanism (EN, HP, BL) for re­ciprocatingly rotating each cutting wheel (100U, 100L) in opposite di­rections through a predetermined angle, respectively. At least one of the side edges (11a, 11b) of each of the cutting teeth (CT) of the cutting wheels (100U, 100L) is defined by an inclined surface forming an acute angle relative to a major surface (10) of the cutting tooth (CT) so as to form a cutting edge, and the outer peri­phery edge (12) is defined by a plane substantially perpendicu­lar to the major surface (10) of the cutting tooth (CT). Namely, there is no sharp edge in the outer peripheries of the teeth of the cutting wheels (100U, 100L) or the free ends of the cutting teeth (CT).
