I rock raked last weekend. Then pulled the rocks over by the driveway. I have hundreds of 1-2 inch thick flat stones. Most pieces are no more than 12"x 12" x 2" If I could break this stuff down, say 1-2 inch pieces. I could use it for the driveway. I was thinking of a V-shaped trough with some sort of turning blades or a log splitter arangement Any ideas, besides a sledge hammer, my rock source is unlimited. I have a Ford 2N with a PTO
