PROBLEM TO BE SOLVED: To provide an agricultural working machine which can exactly grasp a state of an extension ground leveling body, in the agricultural working machine which performs agricultural work by being attached to a tractor.SOLUTION: An agricultural working machine 2 which performs agricultural work by being attached to a tractor 1 comprises: a rotating body which rotates by power from the tractor 1； a ground leveling body 60 for ground-leveling the ground which is arranged at a rear of the rotating body, and tilled by the rotating body； an extension ground leveling body 61 which can be extended at least at one end of the ground leveling body 60 in left and right directions； an extension ground leveling body drive unit 70 which drives the extension ground leveling body 61 in an extension state or in a non-extension state； an indicator lamp 20 arranged at the extension ground leveling body drive unit 70； and a control part 16. The control part 16 determines whether or not the extension ground leveling body 61 is in the extended state, and when the extension ground leveling body 16 is determined to be in the extended state, makes the indicator lamp 20 emit light for giving a notification of the extended state.【課題】トラクタに装着して農作業を行う農作業機において、延長整地体の状態をより的確に把握することができる農作業機を提供することを目的とする。【解決手段】トラクタ１に装着して農作業を行う農作業機２において、トラクタ１からの動力により回転する回転体と、回転体の後方に設置され回転体により耕耘した土を整地する整地体６０と、整地体６０を左右方向の少なくとも一端で延長可能な延長整地体６１と、延長整地体６１を延長状態又は非延長状態に駆動する延長整地体駆動装置７０と、延長整地体駆動装置７０に設けられる表示灯２０と、制御部１６とを有し、制御部１６は、延長整地体６１が延長状態か否か判断して、延長整地体６１が延長状態と判断した場合に表示灯２０により延長状態を報知する発光をさせる。【選択図】図２
