WORKING MACHINE

To provide an autonomously travelling working machine that allows a user in a remote place to check an operation state by transmitting the information on the operation state, and reduces an amount of communication and an amount of battery consumption.SOLUTION: A working machine (1) includes a working part (12), a travelling part (11), a first control part (20) for controlling the working part and controlling the travelling part so that it travels autonomously, a state detection part (21) for detecting an operation state of the working part and the travelling part, and a communication device (30) capable of transmitting information to the outside. The first control part transmits state information on the operation state from the communication device with a predetermined transmission interval, and switches the transmission interval between a first time and a second time longer than the first time on the basis of the detected operation state.SELECTED DRAWING: Figure 1 【課題】自律して走行する作業機において、作動状態についての情報を発信することで遠隔地のユーザが作動状態を確認できると共に、通信量及びバッテリ消費量を削減する。【解決手段】作業機（１）であって、作業部（１２）と、走行部（１１）と、作業部を制御すると共に走行部を自律走行するように制御する第１制御部（２０）と、作業部及び走行部の作動状態を検出する状態検出部（２１）と、外部に向けて情報を発信可能な通信装置（３０）とを有し、第１制御部は、作動状態に関する状態情報を通信装置から所定の発信間隔をもって発信し、発信間隔を、検出された作動状態に基づいて、第１の時間及び前記第１の時間よりも長い第２の時間との間で切り替える。【選択図】図１
