To provide a work vehicle capable of straight-ahead traveling using an automatic steering device even in a farm field in a shape of equilateral polygon.SOLUTION: The traveling vehicle body of the work vehicle is provided with: a work arrangement for performing work in a farm field; a steering member for steering traveling wheels of the traveling vehicle body; an automatic steering device for operating the steering member to cause the traveling vehicle body to automatically travel on a travel route; a position information acquisition device for acquiring position information of the traveling vehicle body; and a control device for operating the automatic steering device to cause the traveling vehicle body to travel along a preset travel route. When the work vehicle is traveled by enabling an area recognition member for turning on or off a recognition traveling state in a work area to acquire work area information or when prerecorded work area information is read, the control device automatically sets a travel route appropriate for the work area.SELECTED DRAWING: Figure 11【課題】 不等辺多角形の圃場であっても、自動操舵装置を用いた直進走行が可能な作業車両を提供する。【解決手段】 走行車体に圃場内で作業を行う作業装置を設け、走行車体の走行輪を操舵する操舵部材を設け、操舵部材を操作して走行車体を走行経路上で自動走行させる自動操舵装置を設け、走行車体の位置情報を取得する位置情報取得装置を設け、自動操舵装置を作動させて走行車体を設定された走行経路に沿って走行させる制御装置を設けた作業車両において、制御装置は、作業領域の認識走行状態を入切する領域認識部材を入操作して作業車両を走行させて作業領域情報を取得するか、記録された作業領域情報を読み込ませると、作業領域に合わせた走行経路を自動設定する構成とする。【選択図】図11
