I rented one of these for the first time last week and all I can say is "WOW." We were able to split about 5 cord of wood in around 7 hours. A lot of it was this twisted, nasty pine but the splitter went through most of it with no problems. It had the four way wedge and it split in both directions, with 2-3 of us working on it we flew through the wood. (now if there was an easy way to stack it all) If they weren't so expensive I would seriously look into a purchase of one. My only issue was that when you are down to just one person it is not near as efficient but what is? I will be renting this awesome machine next year again after I stockpile some more wood again. This is not the one we rented but just a image search of one. The one we rented had a hydraulic lift on it, that we never used but I could see it being handy.
