PROBLEM TO BE SOLVED: To provide a walking paddy field working machine that properly deals with a condition in which a machine is largely inclined right and left along big unevenness of plow sole besides a condition in which the machine is slightly and frequently inclined right and left along small unevenness of plow sole.SOLUTION: The walking paddy field working machine includes right and left traveling wheels, a rolling mechanism 26 for making a differentiation in height from the machine between the right and left wheels and a rolling operation means 31 for operating and handling the rolling mechanism 26 so as to make the machine in parallel with the surface of a paddy field. Flexible parts 20 for allowing the right and left wheels to rise and fall are arranged between the rolling mechanism 26 and the right and left wheels and an urging mechanism 29 for urging the right and left wheels in directions to eliminate difference in height from the machine between the right and left wheels.COPYRIGHT: (C)2010,JPO&INPIT【課題】歩行型水田作業機において、耕盤の小さな凹凸に沿って機体が右及び左に小さく頻繁に傾斜するような状態に加えて、耕盤の大きな凹凸に沿って機体が右及び左に大きく傾斜するような状態に対しても、適切に対応できるように構成する。【解決手段】走行用の右及び左の車輪、機体に対する右及び左の車輪の高さに強制的に差を与えるローリング機構26、機体が田面と平行になるようにローリング機構26を作動操作するローリング操作手段31を備える。右及び左の車輪の昇降を許す融通部20をローリング機構26と右及び左の車輪との間に備え、機体に対する右及び左の車輪の高さの差を無くす方向に右及び左の車輪を付勢する付勢機構29を備える。【選択図】図9
