WORK VEHICLE

To provide a work vehicle which can properly process so as not to leave a region where no work has been performed which occurs during ground work along a travel route.SOLUTION: A work vehicle is configured to determine a region KI where work has been performed already by positional information of a vehicle body by a positioning unit 98 and grounding information of a ground work machine 18 and store the same, and the work vehicle has an information terminal 97 for displaying the region KI where work has been performed already. In addition, the work vehicle is configured to perform adjacent work in a work area xn while making a vehicle body travel along travel routes Y0, Yn which have been calculated and set in advance, and after reaching a finish point Pe of work in the work area xn, determine presence of a region MI where no work has been performed, and if there is the region MI where no work has been performed, generate travel routes ML1, ML2 for processing a region where no work has been performed for processing the region where no work has been performed.SELECTED DRAWING: Figure 19 【課題】走行経路に沿う対地作業中に発生する未作業地を残さないよう適切に処理する。【解決手段】測位装置９８による車体の位置情報と対地作業機１８の接地情報によって既作業地ＫＩを判定して記憶する構成とし、該既作業地ＫＩを表示する情報端末９７を設ける。また、予め演算設定した走行経路Ｙ０，Ｙｎに沿って車体を走行しながら作業エリアｘｎ内を隣接作業する構成とし、作業エリアｘｎ内での作業の終了地点Ｐｅに達して後、未作業地ＭＩの有無を判定し、未作業地ＭＩが有る場合に未作業地ＭＩを作業処理すべく未作業地処理走行経路ＭＬ１，ＭＬ２を生成するよう構成する。【選択図】 図１９
