배기가스 정화 장치(202)의 재생시에 종래보다 더 적합한 제어 구조를 구축하는 것을 과제로 하고 있다. 엔진(201)의 구동을 제어하는 엔진 ECU(311)와, 엔진 ECU(311)와는 별체의 별체 ECU(장치용 ECU)(351, 354∼358)를 구비한다. 엔진(201)을 개동하는 키 스위치(331) 조작에 의거하여 엔진(201) 온도가 소정 이하일 때에 난기운전의 요구를 표시함과 아울러, 엔진(201) 온도가 소정 이상으로 상승할 때에 엔진 ECU(311)이 배기가스 정화 장치(202)의 재생 제어를 개시한다. In order to address the issue of building a control structure more suitable during regeneration of an exhaust gas purification device (202) than conventional control structures, an agricultural work vehicle is provided that comprises an engine ECU (311) that controls the driving of an engine (201) and separate ECU (attachment ECU) (351, 354-358) being separate from the engine ECU (311). The agricultural work vehicle displays a request for warmup operation if the engine (201) temperature is no more than a prescribed temperature, on the basis of key switch (331) operation that starts the engine (201). The engine ECU (311) starts regeneration control of the exhaust gas purification device (202) when the engine (201) temperature rises to at least a prescribed temperature.
