WORK VEHICLE WITH IMPROVED EXHAUST COMPONENT COOLING

摘要

A work vehicle in which a cooling fan is arranged forward of an engine and an exhaust gas purification device is arranged rearward of the engine. An inlet-side exhaust passage connects an exhaust manifold and the exhaust gas purification device. An outlet-side exhaust passage connects the exhaust gas purification device and the exhaust end portion. A first exhaust passage is coupled to the exhaust gas purification device and passes over the exhaust gas purification device to reach beside a first end portion. A second exhaust passage is coupled to the first exhaust passage and extends in a transverse direction and below the exhaust gas purification device.
