PROBLEM TO BE SOLVED: To dispose an exhaust system in a limited space.SOLUTION: Devices 410, 420, 430 consisting of an exhaust system 400 are disposed in parallel in a consistent longer direction with each other. An urea water addition device 420 is disposed at a higher position than an oxidation catalyst device 410 and an urea SCR device 430 between the oxidation catalyst device 410 and the urea SCR device 430. After flowing in the oxidation catalyst device 410 from the front side to the rear side, an exhaust gas flows in a pipeline 422 of the urea water addition device 420 from the rear side to the front side, then flows in the urea SCR device 430 from the front side to the rear side. The urea SCR device 430 is disposed so as to incline in a front-back direction of a wheel loader 100 so that a rear end side of the urea SCR device 430, on which an outlet piping 433 is formed, faces left backward.SELECTED DRAWING: Figure 11 |
