PROBLEM TO BE SOLVED: To easily perform gear shift without performing operation of a clutch pedal when forward/rearward travel switching operation is performed on a slope. SOLUTION: The working vehicle is provided with an actuator 86 for changing the output rotation speed of HST 21; a normal/reverse rotation switching mechanism 23 provided on a power transmission route between an output shaft 68 of HST and an axle; and a normal/reverse rotation switching lever 7 becoming a forward/rearward travel switching operation unit for switching the normal/reverse rotation switching mechanism 23 provided on a drive operation part. The working vehicle is provided with a means 87 for detecting an operation position of the forward/rearward travel switching operation unit; a clutch 61 for switching the normal/reverse rotation switching mechanism; and a controller 81 for controlling these. When the forward/rearward travel switching operation unit switches it in a reverse travel direction from an advancement position or a retreating position, when a timeΔT positioned at a neutral position is shorter than a set time T0, it is controlled such that deceleration is performed from one advancement direction to reach a speed 0 and the normal/reverse rotation switching mechanism is simultaneously switched to perform speed-increase in a reverse direction.
