I bought a 60" W.R.Long Rake in 2010 and have removed overgrowth on 10 acres since then using a 35 hp Kubota L3430. Working just two weeks per year, our property has been transformed from a jungle to a park! It is great at removing most trees under 9" using the chisel teeth of the grapple to sever the roots, then using the loader to push the tree over. I have taken down 12" aspens this way, then hauled them to the brush pile, root and all!!! The problem is I have made so many brush piles that I had to trade in the tractor and grapple for an L5460 and am now shopping for a replacement grapple, and possibly another implement for more selective tree removal like a stump bucket or tree spade. The only problems I have had with the grapple happen when you catch a big root with a single tooth; putting the full force of the tractor on a tooth caught this way can break the tooth, which I have done twice. Much better to back out and take another stab at it.
