I thought y'all might get a kick out of these pictures. A large, 150 year old (at least) white oak had been dropped earlier in the year by a friend of mine. We finally got together to process the trunk into firewood. It was an honest 5+ foot diameter at ground level, and the swell up to the first branches was even larger. The saws used for blocking up the trunk were a Stihl 084 (120cc) with a 60" bar and .404" semi-chisel skip chain, and an 075 (111cc) with a 42" bar and 3/8" round chisel skip chain. The ripping of the large rounds was handled by a pair of Stihl 066s (92cc) with 24" and 28" bars, both running 3/8" pitch chain. Trimming and pre-splitter finish work was handled by a Stihl 046 (76cc) and Dolmar 7900 (79cc), both wearing 20" bars and running 3/8" pitch chain. There was also a Husqvarna 371 and a Stihl 076 hanging around, but they didn't get used. The rounds were handled by a Bobcat with pallet forks and a set of skidding tongs hanging off a boom on the 3-point of a 43hp New Holland tractor. Splitting was handled by a very well used John Deere splitter - 6hp, 11gpm, 4" cylinder. Each round produced better than a half of a face cord of firewood!
