Claims

[Scope of utility model registration request]

In a work vehicle equipped with a position control device having a position switch provided on the left and right side clutches and a continuously variable speed lever, the position control device is provided with a high-speed cut switch, and the high-speed cut switch switches the position switch when the side clutch is activated. The work vehicle is configured such that the circuit is configured to give higher priority, and when the work vehicle is traveling straight, it travels at high speed based on the position switch, and when the direction is changed by actuation of the side clutch, it is decelerated to a predetermined low speed based on the high speed cut switch. speed control device.
