A multi-ratio PTO drive system (10;20) is provided and having a first shaft (12) drivingiy coupied to a second shaft (14) between an engine output (16) and a spiined PTO output stub (90:96) 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 drivingiy coupied to one another. A first gear (21,22,23) of each gear set is keyed on the first shaft (12) and a second gear (31,32,33) is selectively engageabie with the second shaft (14) by a respective selector mechanism. Each selector mechanism is hydraulically activated by pressurised fluid conveyed through respective fluid conveyance bores (51,52,53) in the second shaft (14). The selector mechanisms may comprise respective coupling gears (41,42,43) that are siidabie on the second shaft (14) 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.
