PROBLEM TO BE SOLVED: To smoothly perform ridging and form a favorable ridge slope with strong fixing force by preventing sticking of soil right after driving of a tilling rotary.SOLUTION: The ridger 1 includes: the tilling rotary 31 for excavating a ground surface 5a of a cultivated field 5 and forming a mound A on a lateral outside B a front plate 33 for restraining backward movement of the tilling soil G a swing plate 35 for pressing the surface of the mound A to form a ridge slope 7a a flexurally deformable beating plate 37 for beating and compacting the surface of the formed ridge slope 7a a power transmission mechanism 39 for driving the tilling rotary 31, the swing plate 35 and the beating plate 37 and a beating plate flexure restraining mechanism 141 with a stopper 143 to abut to the back surface of the distal end of the beating plate 37. The mounting angle of the front plate 33, the swing plate 35 and the beating plate 37 in a tilling posture is set in such a state that floating of the distal end 38 of the beating plate 37 is reduced as the stopper 143 abuts to the beating plate 37.COPYRIGHT: (C)2012,JPO&INPIT【課題】耕耘ロータリー直後の土溜まりを防止して円滑な畦付けと、良好で固着力の強い畦法面の成形とを可能にする。【解決手段】本発明の畦付け機1は、耕作地5の地面5aを掘削し、側部外方Bに盛り土Aを形成する耕耘ロータリー31と、耕耘土Gの後方への移動を規制する前面板33と、前記盛り土Aの表面を押圧して畦法面7bを成形する揺動板35と、成形された畦法面7bの表面を叩いて押し固める撓み変形が可能な叩き板37と、前記耕耘ロータリー31と揺動板35と叩き板37とを駆動する動力伝達機構39と、前記叩き板37の先端部背面に当接するストッパ143を備えた叩き板撓み規制機構141と、を具備し、前記前面板33と揺動板35と叩き板37の取付け角度を耕耘姿勢において、前記ストッパ143の当接によって叩き板37先端部38の浮きを小さくしたものである。【選択図】 図12
