PROBLEM TO BE SOLVED: To return a ground working device to a prescribed attitude without any delay, even when a longitudinal inclination of a machine body of a paddy field working machine is relatively large during working at a relatively high speed in the paddy field working machine.SOLUTION: The paddy field working machine supports the ground working device to freely roll around a longitudinal axis of a rear part of the machine body and, on the basis of a detection of an inclination sensor that detects the longitudinal inclination of the ground working machine, actuates an actuator 40 such that the ground working device is retained in the prescribed attitude. The paddy field working machine includes: inclination detection means 46 that detects the longitudinal inclination of the machine body and assistive rolling means 39 that, when the machine body is inclined from the prescribed attitude to the right or left, on the basis of the detection of the inclination detection means 46, actuates the ground working device to rotate inversely to the inclination direction of the machine body.COPYRIGHT: (C)2014,JPO&INPIT【課題】水田作業機において、機体の左右方向の傾斜が比較的大きく比較的高速の場合、対地作業装置が遅れることなく所定姿勢に戻されるように構成する。【解決手段】機体の後部の前後軸芯周りに対地作業装置をローリング自在に支持し、対地作業装置の左右方向の傾斜を検出する傾斜センサーの検出に基づいて、対地作業装置が所定姿勢に維持されるように、アクチュエータ40を作動させる。機体の左右方向の傾斜を検出する傾斜検出手段46を備えて、機体が所定姿勢から右又は左に傾斜すると、傾斜検出手段46の検出に基づいて、対地作業装置を機体の傾斜方向とは逆方向にローリング作動させる補助ローリング手段39を備える。【選択図】図4
