Abstract
A work vehicle includes a cooling fan, an engine, and a diesel particulate filter (DPF) purifying exhaust gas of the engine, placed under a hood in that order, beginning at the front. Exhaust gas from the engine is exhausted through an exhaust passage after passing through the DPF. The cooling fan supplies cooling air to the rear. The DPF is placed such that a length direction thereof follows a width direction of a vehicle body. The exhaust passage includes a first passage, a second passage, and a third passage. The first passage extends forward and upward from the DPF before extending along the length direction thereof on a front side of the DPF. The second passage extends downward from a downstream portion of the first passage. The third passage extends to the rear from a downstream portion of the second passage and also includes an exhaust outlet.
