different animal, my take.
i run an 8000lb pto on mine. a braden lu-4 with 150' of 7/16 cable, and 10' of grade 80 1/2" chain. it has 3 ujoints, 2 bars and 1 carrier bearing. it pulls fast enough, and the nice thing about pto's is that while they dont pull unloaded as fast as most electrics, they pull the same speed under load, as unloaded.
tranny mounted pto speed is determined by engine rpm, direction (fwd/rev) is determined by a 2 direction pto box.
transfer mounted pto speed is determined by the transmission gear. i.e. 1,2,3,4,R.
while people are right that pto's dont work with the engine off, i will say you can work a pto ALL day. a pto is a much tougher winch imo. i could have gone electric, but continue to remain a pto fan.
