I just got one of them down and I am chewing it up. Dropping an oak is very dangerous when they are leaning the wrong way and still dangerous when they are on ground until they are lying flat and not propped up branches. Even on the ground as you cut them up they can roll and fall on you. This one is is not a live oak and was fortunately not huge. I used a 25 inch saw not in the picture and the tree was at least 5 inches thicker.
I used wedges and several chain hoists to pull it away from the house. When on the ground I first cut away as many of the limbs that are not caught under the tree holding it up. Then I cut the limbs that are struck in ground supporting the tree and when almost through them, I pull them away with tractor so I do not get caught when the tree falls to ground level.
The dogs once the chain saw starts generally retreat, but I called them and made them pose for a picture.
I will burn the wood for fuel this winter.
