Not completely true. I have split some stuff with my big boy that would have puked a 20/22 ton unit. But I will agree that for the vast percentage they do a fine job.
The other thing about the high tonnage units is that you don't have to consider or think about log placement. Just put it up there and split it.
LOL, that is a good thought. I don't know much about the different units and have been reading up on this thread since I was the OP. My husband wanted a 4 way wedge and folks seem to be of the thinking that you cannot use a wedge with a 22 ton unit hence the continued back and forth of the 22 or higher tonnage unit. I'd love to just go with a 22 because we really don't need to spend a ton of money on the splitter - however, the wedge could be a deal breaker...I'm not sure.
