I'd have that busted up with my Fiskars in 30 seconds. Maybe a couple minutes with the splitter. If your's wont do it then it sounds like a cry for help.
That looks pretty straight grained. I'm pretty confident that my Ryobi 4 ton electric splitter could handle it. Here's a video I made of my Ryobi splitter in action.
I have a little bitty Didier 20 with a 19 inch stroke rated at probably 8 tons and I have split a lot bigger hedge and oak with it. I bought this little splitter when I lived in town and I would not hesitate to split that round with it, assuming it is short enough to fit.
I also have a 27 ton splitter for longer pieces and know it would get that done.
I don't know about your splitter, but my little Log Boss would turn a 24-inch diameter, three-year-old, white oak round into tooth picks without so much as a grunt.
Now a crotch would make it balk a little... just a little.
I don't know where you live or what size trees you have, but that round really is not that big, man I thought I was gonna be shocked or something, c'mon man.
up yers'...cuz' I think the tire on your other trailer is flat, and you're just clamping the rounds with the ram to haul em' over to that fancy smokehouse with the shiny chimney :tongue2:
I think you can do it. If you split off center like that, she'll go through that like a hot knife in butter. Even if it was 3 yrs. old, I know mine would split that thing like nothing. I've did Elm just as big a few years back. It had to kick in and grunt but she spilt it.
