It took me just over an hour to drop & cut a 24" White Oak into fire wood, was able to drop in in a clear area, had 2 guys hauling the limbs clear, did not have to deal with any obstructions or root ball, and it was a much smaller tree that this one w/o a whole lot of top (it was dying). And the homeowners, who had hired real professionals previously for other jobs, were amazed how fast I got it done, so Brian, I think you are vastly underestimating this thing.
Also, I did not chip any of the branhces, they were going to do that later.
