PROBLEM TO BE SOLVED: To improve work efficiency of a work vehicle by maintaining efficiency of cooling an engine.SOLUTION: A radiator (80) is arranged at an outer portion of an engine (20). A filter (12) is arranged at an outer portion of the radiator (80). A fan (40) is arranged at a portion between the engine (20) and the radiator (80). A hydraulic continuously variable transmission (30) allowing normal/reverse rotation output and shifting the driving force of the engine (20) to drive the fan (40) is provided. By performing shifting actuation of the hydraulic continuously variable transmission (30), a cooling state for sucking outside air from the outer side to the inner side of the filter (12) by performing normal rotation driving of the fan (40) is switched to/from a dust removing state for blowing wind from the inner side to the outer side of the filter (12) by performing reverse rotation driving of the fan (40). A steering part (9) is provided with an operation tool (100) for arbitrarily performing shifting operation of the hydraulic continuously variable transmission (30). |
