I had a 10 acre loblolly pine plantation, 30 years of age, clearcut because of root rot and bark beetle mortality. Harvest was done by Hill Logging, one of the very best that I have ever dealt with. This stand yielded 36 semi loads on the 10 acres. This crew had a tigercat fellerbuncher, one tigercat skidder, a John Deere processor, and a tigercat loader. Took them 2 1/2 days. They averaged 14 loads per day. Average diameter of the logs was about 15".
