Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress reduction of an intake area of a dust preventing net to thereby prevent overheat of an engine.SOLUTION: A working vehicle is equipped with an engine (38) and a hydraulic type continuously variable transmission (48) driving a fan (39) for cooling a radiator (40) and a pedal type or lever type operation tool switching the output rotation of the hydraulic type continuously variable transmission (48) from a normal rotation condition to a reverse rotation condition. That is, the working vehicle has the operation tool as a pedal type first operation tool (28) and is constituted such that a parking brake is activated by stepping down the first operation tool (28), has a first sensor (119) detecting the stepping operation of the first operation tool (28), and a control device (116) switching the hydraulic type continuously variable transmission (48) from the normal rotation condition to the reverse rotation condition in the case the stepping operation of the first operation tool (28) is detected by the first sensor (119).
