As I work outside preparing for the weekend snow I can hear in the distance the sounds of wood being turned into mulch. I am guessing it is work under the power lines. If I had a truck, I would head out to hunt it down and see about getting some firewood. Years ago before I got the wood stove, we had a major wet snow and ice storm that took down a lot of trees. I watched that year of good firewood being turned into mulch and then spit out on the verge.
Before I started heating with wood (about 10 years ago) I would run everything through the chipper that I could shove down it's throat. That would be anything 12" in diameter or less. Didn't matter what kind of wood; pine, maple, oak, locust, it all got chipped. Now, if it's 3" or larger, I keep it. The chipper is almost 20 years old now so it's probably wise to not push it to the limit.
I could hear them today in a different location. I cringed every time I heard the noise. If I just had a truck.
1998 200xp - 12" with an 80hp Cummins Diesel. I bought it new. Everything but the tires, knives and anvil is original. I've been meticulous with oil changes and almost daily greasing of all the bearings. Oh wait, I had to replace the hydraulic lines about 5 years ago too. They were pretty dry rotted and one of them blew out so I replaced them all.
