PROBLEM TO BE SOLVED: To provide a ridging implement which has an improved longitudinal balance between a travel machine frame and the implement on traveling and has good accuracy.SOLUTION: This ridging implement comprising an attaching portion to be attached to the travel machine frame, an offset mechanism portion capable of being laterally moved on the attaching portion, a working portion 20 having a pretreating member 21 and a ridge-making member 40 which are disposed in a state capable of being rotated in the horizontal direction on the rotation center of a power transmission shaft 51 disposed on the movement end side as a rotation support O, and a power transmission mechanism portion 50 for rotating the working portion 20 by power from the travel machine frame is characterized in that the rotation support O is disposed on an intersection O between the rotation center shaft of the ridge-making member 40 and the rotation center shaft of the pretreating member 21 in a plane view, and the power transmission mechanism portion 50 has a power-branching portion 65 on the traveling direction front side of the travel machine frame from the rotation support O. The power is transmitted to the ridge-making member 40 through the power-branching portion 65. The power-branching portion 65 is disposed on the inside of the polyhedral drum 41 of the ridge-making member 40.COPYRIGHT: (C)2006,JPO&NCIPI【課題】 移動時の走行機体と作業機の前後バランスを向上させ、精度の良い畦塗り整形作業を提供する。【解決手段】 畦塗り作業機は、走行機体に装着される装着部と、これから左右方向に移動可能なオフセット機構部と、この移動端側に配設された動力伝達軸51の回転中心を回動支点Oとして水平方向に回動可能に配設されて前処理体21及び整畦体40を有してなる作業部20と、走行機体からの動力によって作業部20を回転駆動させる動力伝達機構部50とを備える。回動支点Oは、平面視において整畦体40の回転中心軸と前処理体21の回転中心軸との交点O上に配置される。動力伝達機構部50は、回動支点Oよりも走行機体の進行方向前側に動力分岐部65を備え、動力分岐部65を介して動力が整畦体40に伝達される。動力分岐部65は整畦体40の多面体ドラム41内側に配設される。【選択図】 図4
