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.

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 tractor includes: a vehicle body; an engine compartment; a driving unit that: is disposed behind the engine compartment, and includes: a brake pedal that includes: a support shaft; and a pedal arm portion; a master cylinder that is operated by the brake pedal and disposed further toward a vehicle-body back side than the support shaft; and a return spring that biases the brake pedal to swing back to a brake off position; and a partition that: is disposed further toward a vehicle-body front side than the brake pedal, and separates the engine compartment and the driving unit from each other, the return spring being engaged to the partition and to the pedal arm portion.
