PROBLEM TO BE SOLVED: To provide a work vehicle capable of preventing fuel from running out and performing work efficiently.SOLUTION: A work vehicle includes: a positioning device 174 for measuring a self-position of a travelling vehicle body 100; a control unit 150 for causing the work vehicle to autonomously travel along a scheduled travelling route R1 set beforehand; a residual fuel amount sensor 61 for detecting a residual fuel amount in a fuel tank 60; and autonomous travelling start instruction means 110 for giving an instruction to start autonomous travelling. When the instruction to start autonomous travelling is given, the control unit 150 determines a residual fuel amount, and if the residual fuel amount is less than a predetermined amount, regulates the start of the autonomous travelling.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】燃料切れを事前に防いで、効率よく作業できる作業車両を提供する。【解決策】走行車体100の自己位置を測定する測位装置174と、予め設定された予定走行経路R1に沿って自律走行させる制御部150と、燃料タンク60内の燃料残量を検出する燃料残量センサ61と、自律走行の開始を指示する自律走行開始指示手段110を備え、前記制御部150は、自律走行の開始が指示されると、燃料残量を判定し、燃料残量が所定の量よりも少なければ、自律走行の開始を規制する。【選択図】図5
