PROBLEM TO BE SOLVED: To provide a paddy field work machine that is subjected to suppression of the amount of oscillation of a rod constituting a regulation mechanism for regulating sagging of a front part of a ground leveling float.SOLUTION: The paddy field work machine includes a regulation rod 85 adopting a vertically-long attitude and connected to a front part of a ground leveling float 24 swingably supported centering on a support shaft core adopting a lateral attitude. A regulation member 87, which has an opening 87H for inserting the regulation rod 85 and which suppresses sagging of the ground leveling float 24 by making an abutting member 86 at an upper end of the regulation rod 85 abut thereon, is provided in a position higher than an undersurface of a main frame 31 extended in a horizontal direction in a front position of a work device.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2016,JPO&INPIT【課題】整地フロートとの前部の垂れ下がりを規制する規制機構を構成するロッドの揺動量が抑制される水田作業機を構成する。【解決手段】横向き姿勢の支持軸芯を中心に揺動自在に支持された整地フロート24の前部に連結する縦長姿勢の規制ロッド85を備えている。規制ロッド85が挿通する開口87Hを有し、規制ロッド85の上端部の当接部材86が当接することにより、整地フロート24の垂れ下がりを抑制する規制部材87が、作業装置の前部位置で左右方向に伸びるメインフレーム31の下面より高い位置に備えられた。【選択図】図6
