To provide an automatic steering system for work vehicle capable of achieving a stable work travel while reducing the number of non-work areas and duplicated work areas by appropriately setting the steering amount of a front wheel 2 when traveling a work vehicle 1 loaded with consumer goods such as fertilizer and nursery plant having an influence on the change amount of the travel direction S of the work vehicle along a travel target route by the automatic steering system in changing the travel direction S of the work vehicle by steering the front wheel 2.SOLUTION: The automatic steering system adjusts, according to sharing loads WF, WR applied to a front wheel 2 or the front wheel 2 and a rear wheel 3, the steering amount of the front wheel 2 when steering the front wheel 2 against a deviation of a work vehicle 1 from a travel target route to travel the work vehicle along the predetermined travel target route.SELECTED DRAWING: Figure 5

    【課題】前輪2を操舵して作業車輌の進行方向Sの変更を行う場合に、その進行方向Sの変更量に影響力を及ぼす肥料や苗等の消費財を積載する作業車輌1を、自動操舵装置によって走行目標経路に沿って走行させる際の前輪2の操舵量を適正に設定して、未作業領域や重複作業領域を減らしながら、安定した作業走行を行うことができる作業車輌の自動操舵装置を提供する。【解決手段】自動操舵装置は、作業車輌1の走行目標経路からの偏差に対して前輪2を操舵して予め定めた走行目標経路に沿って走行させる際の前輪2の操舵量を、前輪2又は前輪2と後輪3に加わる分担荷重WF、WRに応じて調節する。【選択図】図5
