Abstract: A tractor includes: a vehicle body; an engine bonnet that forms an engine compartment; an engine disposed in the engine compartment; a first exhaust-gas cleaning device that is disposed in the engine compartment and purifies exhaust gas discharged by the engine; and a second exhaust-gas cleaning device that is disposed in the engine compartment and purifies the exhaust gas, the first exhaust-gas cleaning device being disposed above the engine such that a long side of the first exhaust-gas cleaning device is substantially parallel to a vehicle-body lateral width direction, the second exhaust-gas cleaning device being disposed behind the engine such that a long side of the second exhaust-gas cleaning device is substantially parallel to the vehicle-body lateral width orientation, and a maximum vertical length of the first exhaust-gas cleaning device is shorter than a maximum longitudinal length of the first exhaust-gas cleaning device.

Abstract: A work vehicle includes: a first exhaust pipe to which engine exhaust is sent; and a second exhaust pipe that has an inlet having an outer diameter larger than an outlet of the first exhaust pipe, the outlet of the first exhaust pipe and the inlet of the second exhaust pipe being disposed in proximity such that the outlet of the first exhaust pipe is positioned inside the inlet of the second exhaust pipe; a partition that divides a cross section of the outlet of the first exhaust pipe into a plurality of divided regions when viewed from the flow direction and partitions the adjacent divided regions at intervals.
