To provide an agricultural work machine capable of reducing the labor required for switching from manual steering traveling to automatic steering traveling.SOLUTION: When a control mode of a travel control unit is a first mode, the travel control unit controls the travel of a machine body based on a reference azimuth TA or a travel path GL calculated based on the reference azimuth TA. When the control mode of the travel control unit is a second mode, the machine body travels in response to an operation of a steering operation tool. An agricultural work machine comprises a straight travel determination unit that determines whether or not the machine body has traveled straight for a predetermined distance D1 or a predetermined time when the control mode of the travel control unit is the second mode. When the straight travel determination unit determines that the machine body has traveled straight for the predetermined distance D1 or the predetermined time, a mode switch unit switches the control mode of the travel control unit to the first mode.SELECTED DRAWING: Figure 12 【課題】手動操舵走行から自動操舵走行への切り替えに要する労力を軽減可能な農作業機を提供する。【解決手段】走行制御部の制御モードが第１モードであるとき、走行制御部は、基準方位ＴＡ、または、基準方位ＴＡに基づいて算出された走行経路ＧＬに基づいて機体の走行を制御し、走行制御部の制御モードが第２モードであるとき、機体は、操舵操作具の操作に応じて走行し、走行制御部の制御モードが第２モードであるとき、機体が所定距離Ｄ１または所定時間に亘って直進したか否かを判定する直進判定部を備え、モード切替部は、直進判定部により機体が所定距離Ｄ１または所定時間に亘って直進したと判定された場合、走行制御部の制御モードを第１モードに切り替える。【選択図】図１２
