What is this attachment?

I was just browsing tractor house (as I love to do even though I just got a new tractor ), and I notisted this strange looking attachment on the 3ph of this JD 3520. It is not completely visible, but you can see part of it in pictures #1, #3, #5. It looks like some sort of landplane/raking device. Does anyone know what this is???

Looks like some sort of land plane. Whoever had it used it on their driveway, notice the gravel on top of the screen.

Looks like some sort of rock hound, used to gather small stones from soil before grading and seeding.
