PROBLEM TO BE SOLVED: To provide a grass mower capable of effectively finely cutting grasses by improving a structure of a cutting blade itself.SOLUTION: The cutting blades 36 arranged so as to freely swing around an axis V in parallel with a rotational axis of a rotary disk 35 in an outer edge of the rotary disk 35 having the rotational axis along a vertical direction are positioned on an upper surface and a lower surface of the rotary disk 35, respectively, and the cutting blade 36 on the upper surface side and the cutting blade 36 in the lower surface side are arranged at the rotary disk 35 so as to freely swing around the same axis V in parallel with the rotational axis of the rotary disk 35.COPYRIGHT: (C)2013,JPO&INPIT【課題】刈刃自体の構成に改善を施すことによって、植立草の細断を効率良く行うことができる草刈機を提供する。【解決手段】上下方向に沿う回転軸を備えた回転ディスク35の外縁部に、回転ディスク35の回転軸と平行な軸芯V周りに自由揺動すべく取付けた刈刃36を回転ディスク35の上面と下面との夫々に位置させ、かつ上面側の刈刃36と下面側の刈刃36とが、回転ディスク35の回転軸と平行な同一の軸芯V周りで自由揺動するように回転ディスク35に取り付けられている。【選択図】図9
