An agricultural work vehicle is disclosed. The agricultural work vehicle according to the present invention includes an exhaust gas treatment device that physically collects harmful components contained in exhaust gas and converts them into harmless components using chemical reaction, and a cabin that protects the driver's seat from being exposed to the external environment. As an agricultural work vehicle, a combination of DOC (Diesel Oxidation Catalyst), which is part of the exhaust gas treatment system, is placed in the engine compartment in front of the cabin, and another part of the exhaust gas treatment system, the SCR (Selective Catalytic Reduction) combination, is located in the cabin outside the engine compartment It is arranged on the side, and the exhaust gas discharge side of the DOC combination and the exhaust gas inlet side of the SCR combination are connected by a mixing pipe, and the silencer combination is connected to the exhaust gas discharge side of the top of the SCR combination at least higher than the cabin. do.농용 작업차가 개시된다. 본 발명에 따른 농용 작업차는, 배기가스에 포함된 유해성분을 물리적으로 포집하고 화학적 반응을 이용해 무해한 성분으로 변환시켜 배출하는 배기가스 처리장치와, 외부 환경에 운전석이 노출되지 않도록 보호하는 캐빈을 구비한 농용 작업차로서, 배기가스 처리장치의 일부인 DOC(Diesel Oxidation Catalyst) 조합이 캐빈 전방의 엔진룸에 배치되고, 배기가스 처리장치의 다른 일부인 SCR(Selective Catalytic Reduction) 조합이 엔진룸 바깥의 캐빈 전측방에 배치되며, DOC 조합의 배기가스 배출 측과 SCR 조합의 배기가스 유입 측이 믹싱 파이프로 연결되고, SCR 조합 상단의 배기가스 배출 측에 적어도 캐빈보다 높게 소음기 조합이 연결되는 것을 구성의 요지로 한다.
