Zusammenfassung:To provide a work machine in which a posture of a cab cannot be changed unless operated according to a predetermined procedure.SOLUTION: In response to satisfaction of a first condition that a shut-off operating section is in a blocking position, a second condition that a lock operating section is in a release position, and a third condition that a posture operating section is operated and, in addition, in response to a fact that the third condition is satisfied last, a controller supplies hydraulic oil to a second actuator to change a posture of a cab. In response to a fact that the first condition or the second condition is satisfied last, the controller notifies that an operating procedure for changing the cab's posture is incorrect through a notification device without supplying hydraulic oil to the second actuator.SELECTED DRAWING: Figure 5 【課題】予め定められた手順で操作しなければキャブを姿勢変化させることができない作業機械を提供する。【解決手段】作業機械は、シャットオフ操作部が阻止位置である第1条件、ロック操作部が解除位置である第2条件、及び姿勢操作部が操作された第3条件の全てが成立し、且つ第3条件が最後に成立したことに応じて、第2アクチュエータに作動油を供給してキャブを姿勢変化させ、第1条件または第2条件が最後に成立したことに応じて、第2アクチュエータに作動油を供給することなく、キャブを姿勢変化させるための操作手順が誤っていることを報知装置を通じて報知する。【選択図】図5
