PROBLEM TO BE SOLVED: To provide a field work vehicle comprising a control capable of achieving proper shift from manual steering to automatic steering.SOLUTION: A field work vehicle comprises: a path setting part which, when a field work is performed by combining straight advance travel and turning travel, sets a target travel path being a travel target in straight advance travel； an automatic steering request part which outputs an automatic steering request requesting to travel on the target travel path in the automatic steering based on an instruction from an operator； an automatic steering travel determination part which determines possibility of the automatic steering travel, and if it is determined that automatic steering travel can be performed, approves the automatic steering request, and if it is determined that the automatic steering travel is impossible, does not approve the automatic steering request； and a notification device which notifies an operator of a reason indicating why the automatic steering travel is impossible, when the automatic steering request is not approved by the automatic steering travel determination part.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2020,JPO&INPIT【課題】手動操舵から自動操舵への適切な移行が実現できる制御を備えた圃場作業車が要望されている。【解決手段】直進走行と旋回走行とを組み合わせて圃場作業を行う際に、直進走行における走行目標となる目標走行経路を設定する経路設定部と、運転者の指示に基づいて目標走行経路を自動操舵で走行することを要求する自動操舵要求を出力する自動操舵要求部と、自動操舵走行の可能性を判定し、自動操舵走行が可能と判定された場合、自動操舵要求を承認し、自動操舵走行が不可能と判定された場合、自動操舵要求を否認する自動操舵走行判定部、自動操舵走行判定部によって自動操舵要求が否認された場合、自動操舵走行の不可能理由を報知する報知デバイスが備えられている。【選択図】図９
