Classification: CPC F  B | IPC F

Claim 10:
11. The working vehicle according to claim 9, wherein
the planetary gear transmission mechanism includes a first planetary gear transmission configured to speed-shift the driving force speed-shifted by the continuously variable transmission to the high speed stage, and a second planetary gear transmission configured to speed-shift the driving force speed-shifted by the continuously variable transmission to the low speed stage lower than the speed of the driving force speed-shifted by the first planetary gear transmission,
the clutch mechanism includes a first clutch device switchable between an engaged state where the driving force of the first planetary gear transmission is transmitted to the traveling transmission shaft and a disengaged state where the driving force of the first planetary gear transmission is not transmitted to the traveling transmission shaft, and
a second clutch device switchable between an engaged state where the driving force of the second planetary gear transmission is transmitted to the traveling transmission shaft and a disengaged state where the driving force of the second planetary gear transmission is not transmitted to the traveling transmission shaft, wherein
the controller changes the rotation speed of the traveling motor so as to reduce a rotation speed deviation between the rotation speed of the traveling motor and a rotation speed in the second planetary gear transmission when the second clutch device is in the disengaged state.
