PROBLEM TO BE SOLVED: To establish a more appropriate control structure than conventional one in regeneration of an exhaust emission control device 202.SOLUTION: An agricultural work vehicle of this invention includes a traveling machine body 1 supported by right and left traveling parts 2, a common rail engine 201 mounted on the traveling machine body 1, agricultural work parts 3 and 5 disposed in the traveling machine body 1, an exhaust emission control device 202 arranged in an exhaust passage of the engine 201, an engine ECU 311 for controlling driving of the engine 201, and a separate ECU 351. The ECU 311 and the ECU 351 are electrically connected with each other, and regeneration control steps S202 and S305 for burning and removing particulate substance deposited in the exhaust emission control device 202 can be executed. The agricultural work vehicle further includes an input member 322 for executing the regeneration control steps S202 and S305, and the input member 322 is connected to the separate ECU 351, and the engine ECU 311 executes the regeneration control steps S202 and S305 by the command of the separate ECU 351 based on the on-operation of the input member 322.【課題】排気ガス浄化装置２０２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】本願発明の農作業車は、左右の走行部２で支持した走行機体１と、走行機体１に搭載したコモンレール式エンジン２０１と、走行機体１に設けた農作業部３，５と、エンジン２０１の排気経路に配置した排気ガス浄化装置２０２と、エンジン２０１の駆動を制御するエンジンＥＣＵ３１１と、別体ＥＣＵ３５１とを備える。両ＥＣＵ３１１，３５１間を電気的に相互に接続し、排気ガス浄化装置２０２内に堆積した粒子状物質を燃焼除去する再生制御Ｓ２０２，Ｓ３０５を実行可能に構成する。再生制御Ｓ２０２，Ｓ３０５を実行させる入力部材３２２を更に備え、別体ＥＣＵ３５１に入力部材３２２を接続し、入力部材３２２のオン操作に基づく別体ＥＣＵ３５１の指令によって、エンジンＥＣＵ３１１が再生制御Ｓ２０２，Ｓ３０５を実行する。【選択図】図１７
