PROBLEM TO BE SOLVED: To provide a tilling rotor capable of preventing miss-attachment of tilling tines during changing tilling tines of the tilling rotor to which different kinds of tilling tines are attached.SOLUTION: A tilling rotor 10 includes: a rotatably supported rotating shaft 11 and a plurality of tilling tines 15 attached to the rotating shaft 11 in the circumferential direction of the shaft with a predetermined spacing at attachment positions with a predetermined spacing in the axial direction of the shaft. A flange is provided to each of the attachment positions of the rotating shaft 11, and right tilling tines 17 of which tip side bends to right side in the axial direction of the rotating shaft 11 and left tilling tines 18 of which tip side bends to left side in the axial direction are attached to respective flanges alternatively in the circumferential direction. The right tilling tines 17 and the left tilling tines 18 attached to the flanges are colored with different hues, and a plurality of same kinds of right tilling tines 17 or left tilling tines 18 neighboring in the axial direction are spirally arranged from one side to the other side in the axial direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】異なる種類の耕耘爪が装着された耕耘ロータの耕耘爪を交換する際に、耕耘爪の付け間違いを防止可能な耕耘ロータを提供する。【解決手段】耕耘ロータ10は、回転自在に支持される回転軸11と、回転軸11の軸方向に所定間隔を有した装着位置に回転軸の周方向に所定間隔を有して取り付けられた複数の耕耘爪15とを備える。回転軸11の装着位置にはフランジが設けられ、フランジには、耕耘爪の先端側が回転軸11の軸方向右側に湾曲する耕耘爪右17及び軸方向左側へ湾曲する耕耘爪左18が周方向に交互に取り付けられている。フランジに取り付けられた耕耘爪右17及び耕耘爪左18は、互いに異なる色彩が付けられ、軸方向に隣接する同一種類の複数の耕耘爪右17又は耕耘爪左18は、軸方向一方側から他方側に向かって螺旋状に配置される。【選択図】図1
