_Very_ much so...540 (6-spline) and 1000 (21-spline) rpm are US
standards; virtually all larger tractors now have both as standard
equipment (interchangeable spindles, not two separate drives); smaller
utility tractors of the homeowner variety will generally be limited to
540 rpm.

Come to think on it, why don't devices with smaller engines have a PTO?

I could imagine a PTO on a lawnmower and a raft of attachements:
* Brush cutter
* Generator
* Black water pump
* Drain snake
* ???


I was thnking the same thing. I would really like a snowblower /
generator / power washer / pump. It would get used infrequently, but
often enough to keep it in good order.
