"The thing I most like about the two stage is that you can control the feed speed with an adjustable flow valve and you can stop and reverse the feed drum with the "crash bar" feed control lever which surrounds the top and sides of the wide end of the feed chute."
I would like to have a hydraulic feed on my BX42 for the same reason, but it is a pretty expensive option. It is kind of hard to grab and hold a branch once that thing starts chipping it...
As for the OP question: My 2520 has 21.5 hp at the PTO and I was able to kill the engine with a 4 inch piece of old hard wood. It will handle softer stuff that size, but it is pushing the limit.
I have run old 4x4 cedar fence posts through there with no problem.
