To provide a field work vehicle capable of performing automatic travel for highly efficiently replenishing agricultural materials in the middle of work travel.SOLUTION: A field work vehicle includes an own-vehicle position calculation section 70 for calculating an own-vehicle position representing a position of a car body, a travel control section 51 for controlling the travel of the car body based on the own-vehicle position and a target path, and a replenishment mode execution section 631 for executing a replenishment travel mode for replenishing agricultural materials at a boundary area of a field in a U-turn shift travel for shifting from the previous travel path to a next travel path. The replenishment mode execution section 631 executes a first replenishment travel mode or a second replenishment travel mode according to arrangement modes of the travel path. In the first replenishment travel mode, after reaching a start point of the next travel path, the field work vehicle retreats to the boundary area, and after the replenishment work, advances to a start point of the next travel path. In the second replenishment travel mode, before reaching the start point of the next travel path, the field work vehicle retreats to the boundary area, and after the replenishment work, advances to the start point of the next travel path.SELECTED DRAWING: Figure 10

    【課題】作業走行の途中で、農業資材を効率よく補給するための自動走行が可能な圃場作業車を提供する。【解決手段】圃場作業車は、車体の位置を示す自車位置を算出する自車位置算出部70と、自車位置と目標経路とに基づいて車体の走行を制御する走行制御部51と、前走行経路から次走行経路に移行するUターン移行走行において、圃場の境界領域で農業資材を補給するための補給走行モードを実行する補給モード実行部631を備える。補給モード実行部631は、走行経路の配置形態に応じて、第1補給走行モードまたは第2補給走行モードを実行する。第1補給走行モードでは、次走行経路の始点に達した後に境界領域まで後進を行い、補給作業の後に次走行経路の始点に前進する。第2補給走行モードでは、次走行経路の始点に達する前に境界領域まで後進を行い、補給作業の後に次走行経路の始点に前進する。【選択図】図10
