PROBLEM TO BE SOLVED: To provide an agricultural work vehicle readily performing reversing operation, without requiring skills for the reversing operation on the part of an operator.SOLUTION: A levee-plastering machine 1 is equipped with a mounting part 10, provided with an offset mechanical part 40 mounted on a traveling machine body 90 and shaking in the right and the left directions and a levee-plastering operation part 50 arranged at the rear thereof. A transmission frame 51, extending from the levee-plastering operation part 50, is mounted freely rotatably on the rear frame 45 installed at the rear end of the offset mechanical part 40. A driving shaft 22, provided with a driving clutch 27 on the front side at the tip and a driving shaft 23, provided with a driving clutch 28 on the rear side at the tip are installed freely rotatably, side by side, in a main frame 13 of the mounting part 10. A freely rotatable driven shaft 30 is passed through the tip of the transmission frame 51 and installed therein, and a driven clutch 31 on the front side connected to the driving clutch 27 on the front side is installed at the front end thereof. A driven clutch 32, on the rear side connected to the driving clutch 28 on the rear side, is installed at the rear end. A rotation fulcrum O of the levee-plastering operation part 50 is arranged in the nearly center between the driving shafts 22 and 23, when viewed in a plane.COPYRIGHT: (C)2009,JPO&INPIT【課題】畦塗り作業部の反転作業を容易にする。【解決手段】畦塗り機1は、走行機体90に装着されて左右方向に揺動可能なオフセット機構部40を備えた装着部10と、この後部に配設された畦塗り作業部50を有する。オフセット機構部40の後端部に設けられた後フレーム45に、畦塗り作業部50から延びる伝動フレーム51を回動自在に取り付ける。装着部10の主フレーム13に、先端部に前側駆動クラッチ27を設けた駆動軸22と先端部に後側駆動クラッチ28を設けた駆動軸23を回転自在に並設する。伝動フレーム51の先端部にこれを貫通して回転自在な従動軸30を設け、この前端部に前側駆動クラッチ27に接続される前側受動クラッチ31を設け、後端部に後側駆動クラッチ28に接続される後側受動クラッチ32を設ける。畦塗り作業部50の回動支点Oを平面視において駆動軸22,23間の略中央に配置する。【選択図】図1
