In the vehicle, the operating lever 21 is set in a neutral operating position N corresponding to the stopped state, a forward operating position F corresponding to the forward moving state, a reverse operating position R corresponding to the backward moving state, and the left and right slow turning state. Left and right slow turning operation positions corresponding to S 1 , S 2 , S
3 , S4 , are configured to be movable and operable in left and right sharp turning operating positions T1 and T2 corresponding to the left and right sharp turning states, respectively, and the forward operating position F, the reverse operating position R, and the Left and right slow turning operation position S 1
, S 2 , S 3 , S 4 to the left and right sharp turning operation positions T 1 , T 2 is allowed after the operation lever 21 is once moved to the neutral operation position N. A work vehicle provided with a guide 34 for a lever 21.
