A tractor transmission includes a change speed mechanism, a shift lever (30) for shifting the change speed mechanism, a super-reduction mechanism (16) for decelerating and outputting power inputted thereto, the super-reduction mechanism having a larger reduction ratio than the change speed mechanism, and an overdrive mechanism (45) for accelerating and outputting power inputted thereto. A single switching device (29) is provided for operating both the super-reduction mechanism and overdrive mechanism. The switching device is shiftable, when the super-reduction mechanism is in neutral, from a state of operating the super-reduction mechanism to a state of operating the overdrive mechanism. |
