PROBLEM TO BE SOLVED: To provide a mowing machine enabling crushing of mowed mown products in an In inexpensive configuration, and provide the crushing blade.SOLUTION: A mowing machine includes: a rotary blade 7 enabling rotation on a blade rotary shaft 9； a crushing blade 10 having a substantially rectangular shape extending a plan view in the longitudinal direction, having a blade rotary shaft 9 being coaxial with the rotary blade 7, enabling rotation along with the rotary blade 7, and for crushing the mown products mowed with the rotary blade 7； a drive unit for rotating the rotary blade 7 and the crushing blade 10； a cover unit 6 for covering the upper surface of the rotary blade 7 and the crushing blade 10, and making a bottom open； and multiple wheels for making the drive unit travel. A space is formed between the cover unit 6 and the rotary blade 7. The crushing blade 10 includes a bent blade 11 making an end edge bend to bounce up.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】安価な構成で刈られた被刈取物の粉砕を可能とした草刈機及びその粉砕刃を提供する。【解決手段】刃回転軸９を中心に回転可能とした回転刃７と、平面視を長手方向に延長された略矩形状として、回転刃７と刃回転軸９を同軸とし、回転刃７と共に回転可能とした、回転刃７で刈り取られた被刈取物を粉砕するための粉砕刃１０と、回転刃７及び粉砕刃１０を回転させる駆動部と、回転刃７及び粉砕刃１０の上面を覆うと共に、下面を開放させたカバー部６と、駆動部を走行させるための複数の車輪とを備える草刈機であって、カバー部６と回転刃７の間に空間が形成されており、粉砕刃１０は、端縁を跳ね上げるように折曲させた折曲刃１１を備える。【選択図】図３
