pto size

[bx24d]

I have a sub cut with 1 3/8 dia, 6 spline pto and cat 1 3pt hitch. I'm looking at purchasing a garden tractor which has a "limited cat 1 three point hitch". Is the PTO the same for all cat 1? Does "limited" mean in height and lift capacity? Just figuring out if I can interchange some of my smaller implements and run a pto generator off of the garden tractor if need be (it is 27 hp diesel).
