PROBLEM TO BE SOLVED: To provide a paddy field working machine advantageous in transportation and storage without causing deterioration in turning property and stability of a machine body in working.SOLUTION: A first working device A wider than the breadth of a travel vehicle body is configured to be changeable between a working state where a first working part 14 coupled to the rear part of the travel vehicle body via a coupling mechanism, and a second working part 15 coupled to the first working part 14 via a coupling part 16 are horizontally aligned adjacent to each other, and a storage state where the second working part 15 is displaced to the first working part side and the lateral width thereof becomes narrower than that in the working state. A second working device B narrower than the first working device A is coupled to the first working device A via a coupling frame 86 so as to displace between a working position adjacent to the first working device A and a retraction position separated from the first working device A and allowing a change-over from the working state of the first working device A to the storage state.【課題】作業時における機体の旋回性や安定性の低下などを招くことなく、輸送や格納などの面において有利にする。【解決手段】走行車体の横幅よりも幅広の第１作業装置Ａを、走行車体の後部に連結機構を介して連結する第１作業部１４と、第１作業部１４に連結部１６を介して連結する第２作業部１５とが左右に隣接して並ぶ作業状態と、第２作業部１５が第１作業部側に変位して作業状態よりも横幅が狭くなる格納状態とに切り替え可能に構成し、第１作業装置Ａよりも幅狭の第２作業装置Ｂを、第１作業装置Ａに連結フレーム８６を介して、第１作業装置Ａに隣接する作業位置と、第１作業装置Ａから離れて第１作業装置Ａの作業状態から格納状態への切り替えを許容する退避位置とに変位可能に連結する。【選択図】図１８
