WORKING VEHICLE AND COMBINE HARVESTER AS THE WORKING VEHICLE

PROBLEM TO BE SOLVED: To enhance efficiency of cooling an engine mounted on a working vehicle.SOLUTION: A working vehicle has: a running speed sensor for detecting a running speed of a machine body, by switchably constituting a rotating direction of a fan 13 to a cooling condition and a dust removing condition; a running distance calculation means for calculating a running distance from the running speed detected by the running speed sensor; and a variable speed actuator for changing a speed of a hydraulic continuously variable transmission 16. The working vehicle further includes a control unit for operating the variable speed actuator so as to switch the cooling condition and the dust removing condition every predetermined time in a condition in which the running speed sensor detects the running stop condition of the machine body and operating the variable speed actuator so as to switch to the cooling condition and the dust removing condition every time when the running distance calculated by the running distance calculating means becomes a predetermined distance.
