I think you need a CDL to haul the weight of that around!
it looks like it would only take about a 10" size log. way over built for the size of stroke.
Here is the link to the log splitter, location is Michigan

Looks Like you could split wood sideways with that thing. I could have used a splitter like that today! I was splitting some kind of elm (I think) that I've never seen before and man was I some tuff stuff. Maybe the toughes I've ever split. Real intertwined grain and it didn't smell to pretty. My Timberwolf Tw-p1 was very slooooow cycling through it.
