I've had a 27 ton Troy Bilt log splitter that I bought from Lowes for well over a decade now. In my opinion, the most important thing to look for in a log splitter is the engine. Honda makes the very best small engine, and all the other brands try to compare to how close they are to Honda, but none are as good. My log splitter starts every time I need to use it. It runs all day, and it's trouble free. Other brands work well when new, but quickly become difficult to start, or keep running.
27 tons has proven to be enough for anything I put on it. I can split anything I can pick up, but I try to keep my rounds in the 12 to 20 inch range. Some are bigger, but it's getting harder and harder to pick up that much oak as I get older. I only use the tilt function when I get a round that is just too heave to pick up. I hate splitting them that way, it's just a lot more work and effort.
I added plywood tables to either side of my splitter, so nothing falls off of it, and when I split a round in half, I can usually keep that half on the plywood, and work on the other half. The fewer times I have to bend over to pick something up, the better!!!
One tank of gas in the splitter will fill up the bed in my Kawasaki Mule. I like to run the engine until it runs out of gas. I normally only split one load per day. Then I still have plenty of energy to do other things. A full day of splitting and stacking wood will wear me out for the next day.
Lowes doesn't sell Troy Bilt splitters anymore. They have Craftsman, but I wouldn't spend any money on that brand. Used to be good, but now it's really bad. I think Northern Tool has some log splitters with Honda engines. I don't think the hydraulics or the rest of the splitter is that different from one brand to another. The only thing that matters is the Honda engine.
