WORKING VEHICLE

PROBLEM TO BE SOLVED: To provide a working vehicle 1 capable of holding an excellent intake state of cooling air by removing dust such as waste straw adhered to a dustproof member 36c, while maintaining flow rate of cooling air required for cooling an engine 31. SOLUTION: This working vehicle 1 includes a pipe 37 to deliver cooling air to the dustproof member 36c, a switching member 38 arranged between the dustproof member 36c and the pipe 37 to pass or shut off cooling air to be directed to a radiator 34 by passing through the dustproof member 36c from the outside of the vehicle 1, a driving motor 39 for operating the switching member 38, an ON/OFF state detecting sensor 23a for detecting a work state, and a control device 100 for controlling the driving motor 39. The control device 100 controls the driving motor 39 so that the switching member 38 may pass cooling air when the work state is determined, and controls the driving motor 39 so that the switching member 38 may shut off cooling air when non-work state is determined.
