PROBLEM TO BE SOLVED: To provide a work vehicle capable of facilitating fuel supply relative to prior art and reducing work load when a fuel residual amount becomes small in a work.SOLUTION: A work vehicle 100 autonomously travelling on a farm field 13 comprises: farm field shape acquisition means for acquiring topography information including position information of an entrance 11 of a farm field 13； fuel residual amount detecting means 305； position information acquisition means 301； and retracting means for, when the fuel residual amount detecting means 305 detects that, a fuel residual amount of an own machine becomes lower than a prescribed amount, stopping a work travel and calculating a movement route from a current position of the machine body to the entrance 11 of the farm field 13, on the basis of the topography information and own machine position information, and moving the own machine to the entrance 11 along the calculated movement route, and stopping the own machine. According to the work vehicle 100, when the fuel residual amount will run out, the own machine can be retreated to the entrance 11 of the farm field 13 by autonomous travel, so that, without run out of the fuel in the farm field 13 and stop of the vehicle, fuel can be easily supplied to the work vehicle 100.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2020,JPO&INPIT【課題】作業中に燃料残量が少なくなった場合に、従来よりも燃料補給をさらに容易とし、作業負担を軽減するようにした作業車両を提供する。【解決手段】圃場１３を自律走行する作業車両１００であって、圃場１３の出入り口１１の位置情報を含む地形情報を取得する圃場形状取得手段と、燃料残量検出手段３０５と、位置情報取得手段３０１と、燃料残量検出手段３０５が、自機の燃料残量が所定量よりも低下したことを検知すると、作業走行を中断して、地形情報及び自機位置情報から、機体の現在位置から圃場１３の出入り口１１までの移動経路を算定し、算定した移動経路に沿って自機を出入り口１１まで移動させて停止させる退避手段とを備えた作業車両１００によれば、燃料が尽きそうになると、自律走行により圃場１３の出入り口１１まで退避できるので、圃場１３内で燃料が尽きて停止することがなく、かつ、容易に作業車両１００の燃料補給ができる。【選択図】 図８
