  • Patent number: 11268614
    Abstract: A working vehicle includes a traveling clutch to be switched between an engaging state and a disengaging state, a brake to brake the traveling device according to an operation of a brake operator, and a controller to perform a braking control to perform the braking, and an auto-switching controller to switch the traveling clutch from the engaging state to the disengaging state. The controller performs a first processing to switch the traveling clutch from the engaging state to the disengaging state when the brake operator is operated in a case where the auto-switching control is valid and a vehicle speed is less than a threshold, and a second processing to prevent the traveling clutch from being switched from the engaging state to the disengaging state even when the brake operator is operated in a case where the vehicle speed is equal to or higher than the threshold.
