(과제) 원활하게 주행차체를 정지시킬 수 있는 작업 차량을 얻는다. (해결수단) 작업 차량은 4륜 구동 상태와 2륜 구동 상태로 스위칭가능한 동력 전달 장치와, 전진위치와 중립위치와 후진위치로 변위가능한 트러니언암을 갖는 유압 무단 변속 장치와, 브레이크 페달의 페달 조작을 검출하는 페달 조작 검출부와, 페달 조작 검출부가 페달 조작을 검출한 경우, 액추에이터를 제어해서 트러니언암을 중립위치로 이동시키는 처리를 행하고, 상기 처리에서는 4륜 구동 상태일 때는 2륜 구동 상태일 때에 비해 액추에이터의 작동 속도를 느리게 하는 제어부를 구비한다.

    [Problem] Provided is a working vehicle capable of smoothly stopping a traveling vehicle body. [Means for Resolution] A working vehicle includes: a power transmission device which selectively sets a four-wheel drive mode and a two-wheel drive mode; a hydraulic continuously variable transmission device which includes a trunnion arm displaceable to a forward movement position, a neutral position, and a backward movement position; a pedaling operation detection unit which detects a pedaling operation for a brake pedal; and a control unit which performs a process of moving the trunnion arm to the neutral position by controlling an actuator when the pedaling operation detection unit detects the pedaling operation and which sets the operation speed of the actuator to be slow in the four-wheel drive mode during the process compared to the two-wheel drive mode.
