Abstract: A work vehicle such as a tractor including a cooling fan (12a) arranged in front of the vehicle's engine main body (1), and is configured to feed air to the engine main body. The work vehicle further includes a DPF (19), which is arranged on one side of the engine main body and purifies exhaust gas exhausted from the engine main body, and an engine hood (7), which covers the engine main body, the cooling fan, and the DPF. An outside air intake port (21) is formed in both side surfaces of the engine hood at a position further forward than the cooling fan. On both side surfaces of the engine hood, a first opening (30) capable of exhausting air inside the engine hood in a direction away from the vehicle's operation seat in side view is formed in a position facing the DPF in the lateral direction.
