PROBLEM TO BE SOLVED: To provide an easy-to-operate walking type working machine.SOLUTION: A walking type working machine 1 comprises: a body 2 provided with at least one front wheel 4, a pair of left and right rear wheels 5, and a working part 3; a pair of left and right traveling motors 9L and 9R provided at the rear wheels; a handle 6 extended rearward and upward from the body; at least one of inclination angle detection means 41 that detects an inclination angle of the body, and downward load detection means 38 that detects a downward load applied to the handle; yaw rate detection means 37 that detects a yaw rate; and a control device 10 that drives and controls the traveling motors. The control device determines whether the body is in a backward tilting state or not on the basis of the inclination angle or the downward load, executes straight-ahead control that sets a rotational speed difference for the left and right traveling motors so as to reduce the yaw rate if determining that it is not in the backward tilting state, and does not execute the straight-ahead control if determining that it is in the backward tilting state.SELECTED DRAWING: Figure 6

    【課題】 操作が容易な歩行型の作業機を提供する。【解決手段】 歩行型の作業機1であって、少なくとも1つの前輪4、左右一対の後輪5、及び作業部3が設けられた本体2と、後輪に設けられた左右一対の走行モータ9L、9Rと、本体から後方かつ上方に延びたハンドル6と、本体の傾斜角を検出する傾斜角検出手段41、及びハンドルに加わる下向き荷重を検出する下向き荷重検出手段38の少なくとも一方と、ヨーレートを検出するヨーレート検出手段37と、走行モータを駆動制御する制御装置10とを有し、制御装置は、傾斜角又は下向き荷重に基づいて本体が後傾状態であるか否かを判定し、後傾状態でないと判定した場合にヨーレートを低減させるように左右の走行モータに回転速度差を設定する直進制御を実行し、後傾状態であると判定した場合に直進制御を実行しない。【選択図】 図6
