PROBLEM TO BE SOLVED: To suppress reduction of exhaust emission purification action in an exhaust emission purification device by reducing distance between an engine and the exhaust emission purification device, suppress reduction of storage capacity of a grain tank, and facilitate supply of urea water to a urea water tank.SOLUTION: An exhaust emission purification device purifying exhaust emissions of an engine E is arranged in a portion between a threshing device and a grain tank. The exhaust emission purification device comprises a DPF 21 eliminating particle substances in the exhaust emissions and an SCR 22 purifying nitrogen oxide substances in the exhaust emissions by reducing the nitrogen oxide substances with ammonia generating from urea water. Longitudinal directions of the DPF and SCR face a machine body front/rear direction. The SCR is arranged side by side on a right side of the DPF. A recess 30 opening on front and left sides is formed in a portion on a front side with respect to a grain-lifting cylinder 18 in a left wall of a grain tank. The SCR enters into the recess. A urea water tank storing urea water to be supplied to the SCR is arranged in a lower part of a step part of an operation part. A water supply port of the urea water tank is arranged in a right lower part right side face of the step part.SELECTED DRAWING: Figure 6【課題】エンジンと排気浄化装置の間の距離を短くして排気浄化装置での排気浄化作用の低下を少なくするとともに、グレンタンクの貯留容量の減少を抑制し、尿素水タンクに尿素水を容易に給水できるコンバインを提供する。【解決手段】脱穀装置とグレンタンクの間の部位に、エンジンＥの排気ガスを浄化する排気浄化装置を設け、排気浄化装置には、排気ガス中の粒子状物質を除去するＤＰＦ２１と排気ガス中の窒素酸化物質を尿素水から発生するアンモニアで還元して浄化するＳＣＲ２２を備え、ＤＰＦ及びＳＣＲの夫々の長手方向を機体前後方向に向け、ＳＣＲをＤＰＦの右側に並設し、グレンタンクの左壁における揚穀筒１８よりも前側の部位に、前側と左側が開放された凹部３０を形成し、ＳＣＲを凹部内に入り込ませ、ＳＣＲに供給する尿素水を貯留する尿素水タンクを操縦部のステップ部の下部に設け、尿素水タンクの給水口をステップ部の右下部右側面に配置した。【選択図】図６
