Abstract
A work vehicle includes: a muffler which flows exhaust from an engine and extends in a transverse direction so as to allow the exhaust from the engine to flow in the transverse direction; and a CVT case for covering a belt-type CVT positioned frontward of the muffler in a longitudinal direction. The CVT case includes a cooling structure for introducing cooling air from outside, cooling the belt-type CVT, and discharging the cooling air from a discharge part. An exhaust duct includes an inflow opening to be connected to the discharge part for allowing the cooling air to flow into the exhaust duct, and an exhaust opening for allowing the cooling air to flow out rearward. The exhaust opening is elongated in an extending direction of the muffler and oriented in a direction that allows the cooling air flowing out to hit the muffler.
