  • Patent number: 8096200
    Abstract: In a tractor which detachably mounts a PTO portion on a transmission portion, a PTO clutch mechanism is arranged in the inside of the PTO portion. Accordingly, a specification which includes the PTO clutch mechanism or a specification which includes no PTO clutch mechanism is selectable depending on whether the PTO clutch mechanism is preliminarily assembled in the PTO portion or not, in a stage at which the PTO portion is assembled. It is also later possible to easily complete assembly by merely mounting the PTO portion on the transmission portion. Further, by reversing the assembly steps, it is possible to easily perform maintenance of the PTO clutch mechanism or other related components.
