Haha neither have I but I got to thinking about one a couple weeks ago. I use my landscape rake most of the time along with my
grapple. They just compliment each other when trimming limbs and cutting saplings. Push everything into windrows or piles with the rake then grab them with the
grapple and off to the burn pile or gulley.
I had mentioned a rear mounted root rake to Travis at
EA the other week. I suggested a 3 point rake similar to the bottom half of the new 55"
EA root rake designed to push brush in reverse. It would be heavier, heavy tines less likely to bend or break and tines spaced farther apart to rake bigger stuff without clogging.
EA has all they can handle right now but it never hurts to ask.
