If a PTO left the drivetrain engaged, you would have no choice but to be driving your mechanism and the drivetrain at the same time. This is generally undesirable. Imagine trying to hang on a bar you are forced to drive away from, for example. The tradeoff of a PTO is that you can't use your drivetrain while it's engaged (plus the design hurdles).



Nothing about a PTO requires the entire gear reduction to take place in the same gearbox as the drivetrain. Rarely is this the case.

You can get around disengaging the drive by lifting the wheels off the ground before engaging the PTO(see 254 or 118*in reveal video* 2013).
