PROBLEM TO BE SOLVED: To enable a more practical shape of a work area to be acquired in an agricultural working vehicle.SOLUTION: A tractor includes a travelling machine body, a going-around antenna route storage part 63, an end position information storage part 61, and an area shape acquisition part 62. The going-around antenna route storage part 63 acquires position information on the travelling machine body on the basis of a positioning signal received by a positioning antenna 6. The end position information storage part 61 stores an offset correction value pre-set for the travelling machine body. The area shape acquisition part 62 specifies the shape of a work area. The going-around antenna route storage part 63 of the area shape acquisition part 62 specifies a going-around antenna route on the basis of the position information on the travelling machine body when the travelling machine body is caused to go around in the work area. An outer peripheral side end route calculation part 66 of the area shape acquisition part 62 specifies an outer peripheral side end route as a shape of the work area on the basis of a going-around direction of the travelling machine body in the going-around travelling, the going-around antenna route, and the offset correction value.SELECTED DRAWING: Figure 3

    【課題】農業用作業車両において、より実際に即した作業領域の形状を取得できるようにする。【解決手段】トラクタは、走行機体と、周回アンテナ経路記憶部63と、端部位置情報記憶部61と、領域形状取得部62と、を備える。周回アンテナ経路記憶部63は、測位用アンテナ6が受信した測位信号に基づいて走行機体の位置情報を取得する。端部位置情報記憶部61は、走行機体に対して予め設定されたオフセット補正値を記憶する。領域形状取得部62は、作業領域の形状を特定する。領域形状取得部62の周回アンテナ経路記憶部63は、作業領域にて走行機体を周回走行させた際の走行機体の位置情報に基づいて周回アンテナ経路を特定する。また、領域形状取得部62の外周側端部経路算出部66は、前記周回走行における走行機体の周回方向と前記周回アンテナ経路とオフセット補正値に基づいて、外周側端部経路を作業領域の形状として特定する。【選択図】図3
