PROBLEM TO BE SOLVED: To provide a working machine uniformly finishing a field by deployment of tilling claws.SOLUTION: The working machine includes a tilling rotor mounted on a rear part of a traveling machine body and having a plurality of tilling claws that are disposed at a circumferential direction of a rotary shaft with respect to each of a plurality of installation parts disposed in an axial direction of the rotary shaft. The plurality of tilling claws include: first tilling claws having a first shape in which horizontal blade parts are curved in a first direction along the rotary shaft second tilling claws having a first shape in which horizontal blade parts are curved in a second direction reverse to the first direction and third tilling claws having a second shape in which horizontal blade parts are curved in the first direction. At least the first tilling claws and second tilling claws are disposed at first installation parts out of the plurality of installation parts, and at least the first tilling claws and third tilling claws are disposed at second installation parts that are adjacent to the first installation parts in the first direction.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】耕耘爪の配置により圃場の均一な仕上がりを実現する作業機を提供すること。【解決手段】作業機は、走行機体の後部に装着され、回転軸の軸方向に配置された複数の装着部のそれぞれに対して前記回転軸の周方向に配置された複数の耕耘爪を有する耕耘ロータを備え、前記複数の耕耘爪は、前記回転軸に沿う第1方向に横刃部が湾曲する第1形状の第1耕耘爪と、前記第1方向とは逆向きの第2方向に横刃部が湾曲する前記第1形状の第2耕耘爪と、前記第1方向に横刃部が湾曲する第2形状の第3耕耘爪と、を含み、前記複数の装着部のうち、第1装着部には、少なくとも前記第1耕耘爪及び前記第2耕耘爪が配置され、前記第1方向において前記第1装着部に隣接する第2装着部には、少なくとも前記第1耕耘爪及び前記第3耕耘爪が配置される。【選択図】図3
