To provide a combine harvester in which a space for arranging an oxidation catalyst and an SCR catalyst can be reduced by compactly integrating the oxidation catalyst with the SCR catalyst.SOLUTION: In an exhaust emission control device (20), an oxidation catalyst (21) is provided in such a posture that exhaust gas flows along a vertical direction of the catalyst (21), and an SCR catalyst (22) is provided in such a posture that an exhaust gas flows along a front and back direction of the catalyst (22). A first support member (52) that supports the oxidation catalyst (21) and extends vertically is provided on the right side of the oxidation catalyst (21). A second support member (51) that supports the SCR catalyst (22) and extends in the front and back direction is provided on the lower side of the SCR catalyst (22). In a plan view, the rear part of the first support member (52) is provided on the rear left side of the front part of the first support member (52) while the first support member (52) is inclined at a predetermined inclination angle with respect to a vertical line extending in the front and back direction. The lower part of the first support member (52) is fixed to a front left part of a top surface of the second support member (51). An aperture (53) is formed in the lower part of the first support member (52). The front left part of the SCR catalyst (22) is made to intrude into the aperture (3).SELECTED DRAWING: Figure 6

    【課題】酸化触媒とSCR触媒のコンパクトに一体化して、酸化触媒とSCR触媒の配置する空間を小さくできるコンバインを提供する。【解決手段】排気浄化装置(20)の酸化触媒(21)を排気ガス流通方向を上下方向に沿わせた姿勢で設け、SCR触媒(22)を排気ガス流通方向を前後方向に沿わせた姿勢で設け、酸化触媒(21)の右側に、酸化触媒(21)を支持する上下方向に延在する第1支持部材(52)を設け、SCR触媒(22)の下側に、SCR触媒(22)を支持する前後方向に延在する第2支持部材(51)を設け、平面視において、第1支持部材(52)を前後方向に延在する仮想線に対して所定の傾斜角度をもって、第1支持部材(52)の後部を、第1支持部材(52)の前部よりも後方左側に設け、第1支持部材(52)の下部を、第2支持部材(51)の上面における前側左部に固定し、第1支持部材(52)の下部に開口部(53)を形成し、SCR触媒(22)における前側左部を、開口部(3)内に侵入させた。【選択図】図6
