It's a shame they went belly up. Customer service beyond reproach. There was a commercial firewood guy on here that kept bad mouthing them. He bragged how many hundreds of cord of wood he split with his processor. Then said he bought the DHT "Just" to split big gnarly knots he couldn't put through his processor. Their warrantee was specific, no commercial use. He argued he only split a few cord with the DHT, so it was a "home owner unit". He showed pics of wedges bent and stuck in giant knots. DHT was a member of this forum and gave us fantastic discounts. They gave him wedges, cylinders, and I think a new beam he twisted. He just kept bad mouthing them, so they started posting receipts of stuff they gave him, right up to a brand new, next size bigger machine.
The reviews we got back then were always good. I had just bought a TSC 35 or 37 ton machine and was happy with it. So, when Lowes started carrying them I looked them over. They looked like they were all common over the counter parts. A friend just rebuilt my old Huskee/TSC 22 ton cylinder for $25, plus the $11 kit. He said the seal kits have every thing for any cylinder of that size. It didn't have to be a Speeko kit, who built the Huskee's. I wouldn't worry about parts. Actually, I've started looking for Box Store splitters with bad cylinders at auctions.
