A multi-ratio PTO drive system is provided and having a first shaft drivingly coupled to a second shaft between an engine output and a splined PTO output stub by a plurality of selectable gear sets. Each gear set delivers a different input-to-output drive ratio and comprises at least a pair of gears drivingly coupled to one another. A first gear of each gear set is keyed on the first shaft and a second gear is selectively engageable with the second shaft by a respective selector mechanism. Each selector mechanism is hydraulically activated by pressurised fluid conveyed through respective fluid conveyance bores in the second shaft. The selector mechanisms may comprise respective coupling gears that are slidable on the second shaft between non-engaged and engaged positions. The coupling gears may serve as pistons within a chamber that can be pressurised wherein the pressurised fluid acts thereupon.
