To provide a work vehicle capable of selecting an appropriate subsequent travelling route even if a work device is equipped in which a lateral deviation is generated between the center of work width and a turning reference point.SOLUTION: A work vehicle travels on a working ground along travelling routes including a plurality of parallel travelling routes extending parallel to each other, and turnaround travelling routes connecting the parallel travelling routes together, and includes a turning information management unit for managing left turning track information on a turning track of the center of work width of a work device at the time of left turning, right turning track information on a turning track of the center of work width at the time of right turning, and a minimum turning radius, and a subsequent travelling route selection unit for determining the selection of a subsequent travelling route, which is the parallel travelling route that the work vehicle travels subsequently to a current travelling route which is the parallel travelling route in which the work vehicle is currently travelling based on the left turning track information, the right turning track information, and the minimum turning radius.SELECTED DRAWING: Figure 7【課題】作業幅中心と旋回基準点との間に横ずれが生じるような作業装置を装備しても、適正な次走行経路の選択できる作業車の提供。【解決手段】作業車は、互いに平行に延びた複数の平行走行経路と、前記平行走行経路同士をつなぐ方向転換走行経路とを含む走行経路に沿って作業地を走行し、 左旋回時の作業装置の作業幅中心の旋回軌跡に関する左旋回軌跡情報と、右旋回時の作業幅中心の旋回軌跡に関する右旋回軌跡情報と、最小旋回半径とを管理する旋回情報管理部と、左旋回軌跡情報と前記右旋回軌跡情報と前記最小旋回半径とに基づいて、走行中の平行走行経路である現走行経路の次に走行する平行走行経路である次走行経路の選択を決定する次走行経路選択部とを備える。【選択図】図7
