PROBLEM TO BE SOLVED: To provide a combine-harvester having an engine device in which intake/exhaust system components are efficiently and compactly disposed around a diesel engine while considering the performance of the intake/exhaust system components.SOLUTION: A combine-harvester comprises: a diesel engine 20 having an intake manifold 75 and an exhaust manifold 64 and a DPF 65 for purifying exhaust gas from the exhaust manifold 64. A support leg body 131 for supporting the DPF 65 is provided above a fly wheel 84 of the diesel engine 20. The DPF 65 is positioned above the fly wheel 84 in a posture that is long in a direction orthogonal to an engine output shaft 83 by connecting the DPF 65 to the top face of the support leg body 131 and, on the other hand, one end side of the DPF 65 in a longer direction is communicated with the exhaust manifold 64.SELECTED DRAWING: Figure 5
