Windy out today so I thought I would just cut up some of the dead stuff on the ground. I know enough to not put trees down when the wind is blowing as they can get away from you. I was loading in to the bucket and heard a snap. turned around and this was on the tractor. 16in hemlock was rotten on one side. Barberchaired about 15ft above the ground. Didn't hurt anything but as soon as I heard it I turned and it was already on the ground. Makes me realize that you can't move fast enough if they are comming down.
