You kind of lost me with the "stop" thing. If your tractor is in gear and moving, with the PTO on, why would it stop when you hit a rock???
I've got one tractor with a non-live PTO that has a brush-hog on it, and I absolutley hate it. Ford 641 with a 5 foot cutter. Cutter will not stop if it hits a rock unless - either the mower slip-clutch slips . . . OR . . . I push in the clutch pedal. With a live PTO, via a two-stage clutch - it's no different. If I hit a rock, my first instinct is to jam down hard on the clutch pedal - and the PTO stops.
Now, I can see where things are different with an independent PTO that does not work via a two-stage engine clutch - but that is just one variation and not the rule for live power.
A decent mower is going to have a slip-clutch or a shear-bolt to protect it from jams, so it should be a non-issue. Most of my mowing, here in NY and in MI, has a lot of stop, go, three-point turns, etc. That kind of mowing is murder with a non-live PTO hooked to a mower. Constantly staring and stopping whenever I touch the clutch pedal.

Jon's Allis has a small front loader and though it doesn't carry much, it serves his needs. It was the hard starting and low power that made him think it was time to replace the old girl. Jon called me to help him discover why his tractor wouldn't start
