PROBLEM TO BE SOLVED: To restrict a decrease in cooling efficiency of cooling equipment and improve its durability in a work vehicle in which a cooling fan performs normal rotation or reverse rotation.SOLUTION: A work vehicle includes a controller (50) for decelerating a hydraulic infinite variable-speed drive (30) to stop driving of a fan (40) in the case that a water temperature equal to or less than a prescribed temperature is detected by a temperature sensor (52) for detecting a temperature of cooling water, and for outputting normal rotation of the hydraulic infinite variable-speed drive (30) to keep driving of normal rotation of the fan (40) in the case that the water temperature equal to or less than a prescribed temperature is detected by the cooling water temperature sensor (52) and a compressor (45) for compressing a refrigerant fed from a condenser (100) is driven. In addition, in the case that the fan (40) is changed over to a dust removal state, driving of the compressor (45) is terminated. |
