PROBLEM TO BE SOLVED: To provide an agricultural working machine capable of appropriately responding to a traveling vehicle side based on information detected by the agricultural working machine side. SOLUTION: The agricultural work machine 1 is used by being connected to a three-point link 10 at the rear of the tractor 2. The agricultural work machine 1 includes a detection unit 91 that detects at least one of peripheral information and state information of the agricultural work machine 1. The agricultural work machine 1 includes a control unit 71 that transmits a signal to the tractor control unit 8 based on the detection of the detection unit 91. The tractor control unit 8 performs predetermined control based on the signal from the control unit 71. [Selection diagram] Figure 1【課題】農作業機側で検知した情報に基づいて走行車側で適切に対応できる農作業機を提供する。【解決手段】農作業機１は、トラクタ２の後部の３点リンク10に連結して使用する。農作業機１は、この農作業機１の周辺情報及び状態情報の少なくともいずれか一方を検知する検知部91を備える。農作業機１は、検知部91の検知に基づいてトラクタ制御部８に信号を送信する制御部71を備える。トラクタ制御部８は、制御部71からの信号に基づいて所定の制御を行う。【選択図】図１
