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.

Abstract: A work vehicle has a ground-work unit that is mounted under a frame supported by front wheels and rear wheels and disposed forwardly of the front wheels. The work vehicle includes a steering wheel supported to a steering post and consisting of spokes and a ring. A man-machine interface face formed in the steering post downwardly of the steering wheel and around a rotational axis of the steering wheel includes a display face having a flat panel display and an operation face having an operation input device. The steering wheel is greater in size than the flat panel display as seen in the direction of rotational axis of the steering wheel, and the operation face is greater in length than the flat panel display in the direction of vehicle width.
