He heats two homes, both houses' hot water, and a decent-size shop with wood, so he burns way more than 8 cord/season. There are a lot more than a dozen of those racks around. I'd guess 40-50?
The racks we build for wood to sell are 1/2 cord. The new one we built (pictured above) was for junk wood to toss in the Woodmaster, so it was a bit larger than that. Surprisingly, his bigger tractor (A Case 95 with a Woods loader) lifts them with no problem, even full of wet Hickory. They all live outdoors. There are often several together. That, combined with the steel roof lets the wood get plenty dry before it's burnt or sold.
He has had four of the medium-size Case tractors in the last several years. He tried one with a cab, but we always found it to be a pain to get in and out when you're doing any work with it and didn't like the loss of maneuverability in the woods. It's one thing to catch a couple branch ends with the ROPS. It's another to have to replace a big piece of glass.
