PROBLEM TO BE SOLVED: To provide a mowing blade which, in a region where an object to be mowed and not to be mowed are mixed, can selectively mow the object to be mowed and prevent both an obstacle and the mowing blade from being damage even when the blade comes into contact with an obstacle which is not to be mowed.SOLUTION: A disk-like mowing blade 1 rotatable in a circumferential direction includes: a rotational shaft 11 to which a rotational force is delivered a peripheral part 12 provided in a periphery of the rotational shaft 11 and a plurality of cutting spokes 13a-13f having blade tips 14a-14f which are provided between the rotational shaft 11 and the peripheral part 12 in a radial direction and which advances in a rotational direction X of the mowing blade 1.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】刈り取り対象物と非刈り取り対象物とが混在した領域において、刈り取り対象物を選択的に刈り取ることができるとともに、刈り取り対象物とは異なる障害物に接触した場合であっても、当該障害物及び草刈刃の双方の破損を防止することができる草刈刃を提供する。【解決手段】円周方向に回転可能な円板状の草刈刃1であって、回転用の動力が伝達される回転軸部11と、回転軸部11の周囲に配置された外周部12と、回転軸部11と外周部12との間に半径方向に沿って設けられ、草刈刃1の回転方向Xに進行する刃先14a~14fを有する複数の切断スポーク13a~13fとを備える。【選択図】図2
