The 30 ton log splitters are one of the biggest available with the 5" diameter cylinder. The 30 ton Iron & Oak log splitters all come in the horizontal position only. Also on this page are the 22 ton FAST CYCLE log splitters that are built the same as 30 ton units except the cylinder diameter size is 4" instead of 5" giving you a little less splitting force but giving you a 30% faster split time. If you want horizontal and vertical then please look at the 26 ton or 34 ton models. American built to last!
