Most trees come with bark.
I was thinking more that you had a lot of “squarings” from the outside of the cord when the rest of the wood is then machined, so generally higher bark:wood ratio
A local firewood supplier here has so much cordwood in stacks that it can be seen on google earth 🙂
He stores to season for a couple of years or so, then loads the cords into a logger/splitter machine. Deliveries are in the back of a tipping Defender110, or in a tipping trailer that takes two “loads”. Its a pretty big set up.
My mates who do firewood as a side line on the other hand have a tractor mounted splitter like yours, a couple of big eff-off chainsaws and a pickup truck and some farm buildings to store chopped wood under cover. They do it for beer money really, I dont think they could make enough fulltime from it to give up the day jobs as a farmer and a landscaper.
