A work vehicle such as a tractor including an engine (5) and a fan shroud (21). The engine (5) includes a DPF (diesel particulate filter: 51) for purifying exhaust gas. The fan shroud (21) is disposed ahead of the engine (5). The DPF (51) includes a soot filter (62) for collecting PM (particulate matter) in exhaust gas. The engine (5) further includes a pressure difference sensor (65) for detecting a pressure difference between an upstream side and a downstream side of the soot filter (62) of the DPF (51) in a direction in which exhaust gas flows. The pressure difference sensor (65) is supported by the fan shroud (21).
