PROBLEM TO BE SOLVED: To avoid lowering of working efficiency of a pruning machine.SOLUTION: The pruning machine 10 which reciprocates a first pruning blade 16 and a second pruning blade 17 in a relative manner in a predetermined direction by power of an engine 13 and cut an object off by shear force of the first pruning blade 16 and the second pruning blade 17, comprises: a plurality of first shear edges 19 and a plurality of second shear edges 20 provided to the first pruning blade 16 a plurality of third shear edges 32 and a plurality of fourth shear edges 33 provided to the second pruning blade 17 and a saw 22 provided to the first pruning blade 16, where the saw 22 includes a plurality of cutting edges 27. A range in which the plurality of second shear edges 20 are provided in the predetermined direction: is wider than a range in which the plurality of first shear edges 19 are provided in the direction and includes a range in which the plurality of fourth shear edges 33 are provided in the direction.COPYRIGHT: (C)2015,JPO&INPIT【課題】刈込機の作業効率が低下することを回避する。【解決手段】エンジン13の動力で第1の刈刃16と第2の刈刃17とを相対的に所定方向に往復動作させ、第1の刈刃16と第2の刈刃17とのせん断力で対象物を切断する刈込機10であって、第1の刈刃16に設けた複数の第1せん断刃19及び複数の第2せん断刃20と、第2の刈刃17に設けた複数の第3せん断刃32及び第4せん断刃33と、第1の刈刃16に設けた鋸22と、を有し、鋸22は複数の切断刃27を備え、複数の第2せん断刃20を設けた所定方向の範囲は、複数の第1せん断刃19を設けた所定方向の範囲よりも広く、かつ、複数の第4せん断刃33を設けた所定方向の範囲を含む。【選択図】図1
