PROBLEM TO BE SOLVED: To provide a mowing blade in which, in comparison with a conventional product, 1 the cut grass is floated to facilitate passing the next cutting blade, 2 the double cutting is reduced, 3 the mowed grass is discharged outside to prevent the winding, and 4 the scattering of the grass to a face is reduced.SOLUTION: A cutting blade is provided at high-speed rotation, and therefore it is required for achieving these 4-items that processing is simple, arrangement is simple and balance is preferable. Fig. 1 shows a configuration of 2-blades. In the same way about 3-blades and 4-blades, the flank face of each blade comes to the upper part and the tilt of the blade surface has a structure inclining several degrees downward as going to the outside, and thereby the same effect can be expected.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】従来の製品に比べて 1、切った草を浮かして次の切り刃を通りやすくする。2、2度刈りを少なくする。3、刈り草を外側に排出して巻き付きを防ぐ。4、顔面への草の飛散を少なくする。【解決手段】 刈り刃については高速回転であることから、これら4項目を実現するためには加工が簡単で装備がシンプルでバランスが良いことがあげられる。図1は2枚刃の形態を示している。3枚刃、4枚刃についても同じように刃の逃げ面が上部に来て、刃面の傾斜を外側に向かうにつれて下方に数度傾く構造で同じ効果を期待できる。【選択図】図1
