PROBLEM TO BE SOLVED: To provide a more favorable control structure with respect to regeneration of an exhaust emission control system than a conventional one.SOLUTION: An agricultural work vehicle includes an engine ECU 311 controlling driving of an engine, and separate ECUs (device ECUs) 351, 354-358 separate from the engine ECU 311. In response to an operation of a key switch 331 for starting an engine, when an engine temperature is below a prescribed value, a request for warm-up operation is displayed. When the engine temperature increases to the prescribed value or more, the engine ECU 311 starts regeneration control of an exhaust emission control system. 【課題】排気ガス浄化装置の再生に際して従来より更に好適な制御構造を構築する。【解決手段】エンジンの駆動を制御するエンジンＥＣＵ３１１と、エンジンＥＣＵ３１１とは別体の別体ＥＣＵ（装置用ＥＣＵ）３５１，３５４〜３５８とを備える。エンジンを始動するキースイッチ３３１操作に基づき、エンジン温度が所定以下のときに、暖機運転の要求を表示すると共に、エンジン温度が所定以上に上昇したときに、エンジンＥＣＵ３１１が排気ガス浄化装置の再生制御を開始する。【選択図】図１７
