after using a Fecon tree shredder. I shredded a 2 acre patch of small (4") trees interspersed with big mature cottonwoods, and oak trees. The midsize trees over 4", up to about 14", I have cut down and split for firewood, and burned the remainder. All stumps are cut down to ground level. My question is what tool would be best for gathering up the massive amount of trash and chunks left by the tree shredder. A rock rake at just above ground/stump level? A drag harrow seems like it would fill up, and ride over the trash after just a few feet. Any experience or suggestions? It would be appreciated.
