tonnage is nice but I find I’m more frustrated by slow cycle time so be careful on that. higher tons is usually larger cylinder and if it’s not matched with a larger pump and engine it can be really slow
Also don’t compare manufacturers tonnage ratings only. look at the diameter of the cylinder and their operating pressure. many times the advertised tons is at some fictitious pressure much higher than the actual unit runs with relief setting.
I saw one unit I don’t remember the brand with outrageously high tons advertised. if you work backward with the math it required 3750 psi to reach that number when the components were typical 3000 PSI industrial and the relief valve was actually set at 2750 which means it’s only maxing about 2/3 of its advertising paper copy.
I found my 4 inch splitter with log lift handles anything that I can physically handle myself. I just recently built a 3 inch splitter and I use that for almost everything because it’s less than four second cycle out and three second cycle back. but I arbitrarily decided I don’t take anything over about 18 inches for the same physical reasons. that wouldn’t apply to a woodlot situation or to what you probably want
