PROBLEM TO BE SOLVED: To provide a configuration by which the shape of a work area can be acquired easily in an agricultural working vehicle.SOLUTION: A tractor as an agricultural working vehicle includes a contour registration point storage part 61 as a position information storage part, and an area shape acquisition part 62 as a control part for acquiring the shape of an area. The contour registration point storage part 61 can store position information based on a positioning signal from a positioning system received by a positioning antenna 6 (or a portable positioning device that can be moved independently). The area shape acquisition part 62 specifies the shape of an area (e.g., a work area where agricultural work is performed) formed based on a plurality of pieces of the position information stored in the contour registration point storage part 61.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】農業用作業車両において、簡単に作業領域の形状を取得できる構成を提供する。【解決手段】農業用作業車両としてのトラクタは、位置情報記憶部としての輪郭登録点記憶部61と、領域の形状を取得する制御部としての領域形状取得部62と、を備える。輪郭登録点記憶部61は、測位用アンテナ6(又は独立して移動させることが可能なポータブル測位装置)が受信した測位システムからの測位信号に基づく位置情報を記憶可能である。領域形状取得部62は、輪郭登録点記憶部61に記憶された複数の位置情報に基づいて形成される領域(例えば、農作業が行われる作業領域)の形状を特定する。【選択図】図3
