Abstract
A system for transmitting power from an engine shaft to a power take-off (PTO) shaft of a utility vehicle, comprising a transmission having an input shaft coupled to the engine shaft and an output driveably connectable to one or more driven axles of the vehicle. A synchronised shift device is operable to selectively connect an output shaft thereof to one of the transmission input shaft and output, said output shaft further being driveably connectable to the PTO shaft. The synchronised shift device comprises inner and outer coaxially aligned and respectively rotatable input bodies alternately connectable to the shift device output shaft, with the inner input body connected to the transmission input shaft and the outer input body driveably connected to the transmission output. The arrangement provides switching between engine speed and ground speed operation of the PTO.
