PROBLEM TO BE SOLVED: To provide a paddy field working machine which can avoid the deterioration of working efficiency during work at a farm field while being enabled in favorable movement and traveling in an advantageous state that a working device does not contact with wheels or the like of a traveling machine body during moving traveling, and does not contact with an outside object.SOLUTION: A working device 4 is connected to a rear part of a traveling machine body so as to be liftable over a working position and a maximum ascending position by the operation of a lift operation mechanism 2, the working device 4 can be divided into a pair of left and right divided working device portions, furthermore, the left and right divided working device portions are switchable in working postures in which the portions are connected in postures going along the machine body lateral direction, and accommodation postures in which the portions are divided to left and right directions in postures going along body fore-and-aft directions, and accompanied by the start of revolving traveling, the lift operation mechanism 2 is operated so that the working device 4 is lifted up to an intermediate set position H2 which is set smaller in a set amount than a maximum lift position H1 from the working position.COPYRIGHT: (C)2014,JPO&INPIT【課題】移動走行中には作業装置が走行機体の車輪等に接触したり、外物に接触する等の不利のない状態で、良好に移動走行することが可能でありながら、圃場での作業中において作業能率の低下を回避することが可能となる水田作業機を提供する。【解決手段】走行機体の後部に、昇降操作機構2の作動により作業位置と最大上昇位置とにわたり昇降自在に作業装置4が連結され、作業装置4が、左右一対の分割作業装置部分に分割可能であり、しかも、左右の分割作業装置部分が、機体横幅方向に沿う姿勢で連結される作業姿勢と、体前後方向に沿う姿勢で左右に分割される格納姿勢とに切り換え自在に構成され、旋回走行が開始されるに伴って、作業装置4が作業位置から最大上昇位置H1よりも設定量低く設定された中間設定位置H2にまで上昇するように昇降操作機構2を作動させる。【選択図】図9
