PROBLEM TO BE SOLVED: To provide a paddy field working machine which has a sowing device and a fertilizing device in a state arranged in a longitudinal direction in a working portion, thereby simplifying the configuration, and which can well sow seeds in a state not scattering seeds in a lateral direction, even when sowing seeds spacedly.SOLUTION: In the paddy field working machine, a working portion (A) is connected to the rear portion of a travel machine frame through a link mechanisms 5 in a state capable of being lifted or lowered and in a state capable of being rolled on a rolling axis X arranged in the longitudinal direction of the machine frame, the working portion (A) has the sowing device 9 and the fertilizing device 10 in a state arranged in the longitudinal direction, and a plurality of seed-feeding portions 28 in the sowing device 9 is disposed in a state placed in the approximately equal height to the rolling axis X.【課題】作業部に播種装置と施肥装置とを前後に並ぶ状態で備えて構成の簡素化を図ることが可能なものでありながら、点播を行う場合であっても種子が横方向にばらつくことを抑制した状態で良好に播種を行えるようにする。【解決手段】走行機体の後部にリンク機構５を介して昇降自在並びに機体前後向きのローリング軸芯Ｘ周りでローリング自在に作業部Ａが連結され、作業部Ａが、播種装置９と施肥装置１０とを前後に並ぶ状態で備えて構成され、播種装置９における複数の種子繰出し部２８がローリング軸芯Ｘと略等しい高さに位置する状態で備えられている。【選択図】図３
