Abstract: A work vehicle having a hood for covering an engine room is disclosed. The engine room has a first region and a second region partitioned from each other, the engine room being configured such that air can be introduced from outside of the hood to the first region. A radiator is disposed in the first region, and air flows through the radiator from the first region to the second region. In the second region, the engine and an accessory unit for the engine are provided. The work vehicle includes an adjusting device for adjusting an amount of the air that flows from the first region to the second region.

Abstract: A mower includes: a driver's seat provided to a vehicle frame. A transmission is arranged at least partially below the driver's seat. An engine arranged rearward of the transmission such that a bottom end of the engine is positioned higher than a bottom end of the transmission.
