I have a Parker clutch on my Exmark mowers and they have held up for over 10 years. As far as blade engagement, the mechanic at Toro told me to always engage at full throttle. He also reaffirmed his statement with the users manual.
My Gravely has an Ogura GT 2.5 clutch and I engage(and disengage) at between 1/2 & 3/4 throttle. I seem to recall a discussion of this in another thread where a user(knowledgeable about PTO clutches) recommended NOT engaging at full throttle for technical longevity reasons. If user Lawn Mower Fanatic happens upon this thread he can probably point us to the thread containing that conversation(I have yet to master the search function on these forums).
I have a mower was a manual.
The deck I am using came off of one with a electric.
I can still use it as a manual but want to start using a electric pto.
Have never used one before so want some info on what people like yourself that know about them think is the best ones to use.
From what I have been told I should go with a adjustable one.
I strongly recommend that you NOT convert your machine from a manual clutch to an electric clutch.
A conversion of this nature involves many considerations some of which are engine charging system output, engine crankshaft size, transmission drive pulley location, relocating pulleys, belt tensioners, electrical system, PTO switch location, safety of operation, choosing a suitable clutch from the 300 or so available, sizing of V belts, the list goes on!!!
You could easily spend more than the machine is worth if it is was fully operational before you started.
Just some thoughts!!

So I went with a Warner 5218-5
My thinking was bobcat and ex mark uses them so they must be good.
Started the mower the blades engaged first flip of the switch. I went right for the two foot tall grass did awesome no belt slipping.
