PROBLEM TO BE SOLVED: To provide a field work vehicle in which automatic running is smoothly started from a desired work restart position even if the field work in the automatic running is interrupted and the work is separated from the target travel route. SOLUTION: The field work vehicle has a departure position Pb at the time of departure, or a departure travel route LM(4) which is a target travel route at the time of departure, as departure information relating to the departure of the vehicle body that occurred during field work in automatic traveling. And a restart recording path LM(4) used when restarting the field work after the departure are determined based on the disconnection information, and a return travel path LM(4) or a return position Pb is returned. A work return management unit that manages the work return management unit is provided, and the work return management unit includes a determination unit that determines whether or not a transition from the manual travel to the automatic travel is possible in the manual return travel in which the vehicle body is heading for the restart travel route. [Selection diagram] Fig. 4【課題】自動走行での圃場作業が中断され、目標走行経路から離脱しても、所望の作業再開位置からスムーズに自動走行が開始される圃場作業車を提供する。【解決手段】圃場作業車は、自動走行での圃場作業中に発生した車体の離脱に関する離脱情報として、離脱時の離脱位置Ｐｂ、または離脱時の目標走行経路である離脱走行経路ＬＭ（４）を記録する離脱記録部と、離脱後に圃場作業を再開する際に用いる再開走行経路ＬＭ（４）を、離脱情報に基づいて決定し、再開走行経路ＬＭ（４）または離脱位置Ｐｂへの復帰を管理する作業復帰管理部とを備え、作業復帰管理部は、車体が再開走行経路に向かう手動復帰走行において、手動走行から自動走行への移行が可能であるかどうかを判定する判定部を有する。【選択図】図４
