I run a 28 ton Swisher with a 10 1/2 B&S;engine. To tell the truth I think it is over powered for most of what we are doing right now. I can idol the engine, or maybe about 1/4 throttle, and I am splitting some really nasty large elm. 20" rounds and a fair number of tough crotch pieces. So far the splitter has just barely slowed down and hasn't even thought about stalling while splitting. I love this thing My wife or the kids run the lever and I position the rounds. Works great so far. I can't say what the troy-built unit is like, but the power level is right, IMHO.
