PROBLEM TO BE SOLVED: To provide a rotary working machine having thirty-eight tilling tines that finish soil uniformly after tilling, without making its arrangement complex.SOLUTION: A rotary working machine includes a cylindrical or columnar tine shaft AX first to thirty-eighth tilling tines K1 to K38 mounted on the outer periphery of the tine shaft AX in such a manner as to extend in the radial direction of the tine shaft AX and curved so that their tips protrude a locking portion where the tilling tines are locked in such a manner as to extend in the radial direction of the tine shaft AX a straight blade portion and a curved blade portion. Thirty eight tilling tines are arranged in the order of the first to thirty-eighth tilling tines from left on the outer periphery of the tine shaft AX. The first to thirty-eighth tilling tines are arranged in specific positions on the outer periphery of the tine shaft.COPYRIGHT: (C)2014,JPO&INPIT【課題】構成を複雑にすることなく、耕耘後の土の仕上がりが均一となる38本の耕耘爪を有するロータリー作業機を提供する。【解決手段】円筒状または円柱状の爪軸AXと、爪軸AXの外周に、爪軸AXの半径方向に延びるように取り付けられ、先端が張り出すように湾曲した第1耕耘爪K1~第38耕耘爪K38とを備え、耕耘爪が、爪軸AXの半径方向に延びるように固定される固定部と、直刃部と、湾曲刃部とを備え、爪軸AXの外周に、左から第1耕耘爪~第38耕耘爪の順に38本配置するロータリー作業機において、前記爪軸の外周の特定の位置に前記第1耕耘爪~第38耕耘爪が配置される。【選択図】図2
