Abstract
A working vehicle includes: a vehicle body; a linkage device configured to link a working device to the vehicle body; a prime mover provided on the vehicle body; a traveling device configured to cause the vehicle body to travel; a transmission device configured to transmit power from the prime mover to the traveling device and perform a speed change process to change a speed of the vehicle body; an increase-in-speed detection device configured to detect an increase in speed of the vehicle body; and a speed change restraint unit configured such that, during the speed change process performed by the transmission device, when the increase in speed detected by the increase-in-speed detection device has become equal to or greater than a threshold, the speed change restraint unit stops the speed change process performed by the transmission device.
