I'll disagree a bit...No. You must engage at idle speed. Sorry if I misread your original question.
You SHOULD always engage your PTO at idle speed. Engaging it at higher RPM is very doable but very hard on clutches, PTO shafts & the whole gear train.
I've never had issues disengaging PTO at any RPM. I always waited until there was no load on the PTO train or what not though.
In old machines with a live PTO something spinning the PTO would keep moving as if you had the clutch in gear regardless of the clutch being in or out. I don't think they have made machines like that in the past decade or 2 though. Some new HST machines are like that, but the HST intrinsically makes that problem moot as it won't transmit power unless you hit the go pedal. I think my L3200 was that way, but never actually tried to propelled with the clutch in & go pedal down based on the kinetic energy stored in my rotary cutter.
