I planted 16 acres of hardwoods on my 35 acres and in the middle was an overgrown section that was just too wooly for me to clear and reclaim by myself. A neighbor had a similar situation and found a local guy with a "Mulcher" that is actually a, what we call it in our area, Bobcat with a set of hammers on the front. You'll see it in the pictures.
(All of the "overgrown and Mulcher" pictures were taken last week with the Iphone held in my normal position with the Home button on the left. All of the "cleared" pictures were taken today with the Iphone held as Kennyd suggested. If not correct rotation, one of the overworked, under paid Mods will have to help me out again with rotating the pictures. Thanks for your help.)
Picture 1 is in the same general area as picture 11 in an "after and before" sequence. The clearing took 2 & ˝ hours @ $150 per hour. The trees / brush were chewed up into pieces about the size of my forearm. He said in our area, the wood would decay in about 5 to 6 months. Almost all of it is small enough to drive a bush hog over without doing any damage. I have picked up the bigger pieces and will burn them later.
