PROBLEM TO BE SOLVED: To provide a tiller capable of corresponding softly to even a deformation of a tilling pawl part and the kind change of a rotor plate, if any, thereby to remove a deposit on the tilling pawl part.SOLUTION: A rotary brush 52 is interposed between a rotor plate 44 and a soil-removing cover 31. The rotary brush 52 comprises: a brush shaft 51 parallel to a tilling shaft 42 and a brush part 53 made of nylon or a metal extending from the brush shaft 51 to the periphery. In response to the power (or the rotation force of a prime mover 33) from a transmission mechanism housed in a transmission case 34, the tilling shaft 42 and the brush shaft 51 rotate in the same direction, and a plurality of rotor plates 44 attached to the tilling shaft 42 rotate so that a rotary brush 52 rotates in contact with the tilling pawl 46 while a tilling pawl part 46 of the outer circumference of the rotor plate 44 rotating, thereby to remove soil and weed having stuck to the tilling pawl part 46.COPYRIGHT: (C)2015,JPO&INPIT【課題】耕耘爪部の変形やロータ板の種類変更があっても柔軟に対応して耕耘爪部への付着物を除去することの可能な耕耘機を提供する。【解決手段】ロータ板44と土よけカバー31との間には回転ブラシ52が設けられる。回転ブラシ52は、耕耘軸42に平行なブラシ軸51と、ブラシ軸51から周囲に広がるナイロン製や金属製等のブラシ部53とを有する。伝動ケース34に収容された伝達機構からの動力(原動機33の回転力)を受けて耕耘軸42及びブラシ軸51が同方向に回転し、耕耘軸42に取り付けられた複数のロータ板44が回転することによってロータ板44の外周部の耕耘爪部46で土壌を耕耘しながら、回転ブラシ52が耕耘爪部46と接しながら回転して耕耘爪部46に付着した土や草を取り除く。【選択図】図2
