Gordon, since I myself have not used any ground engaging impements yet, it is not clear to me what implements are used for what purposes. I can tell you what's on the dealer's lots. The most common are rakes. You can add flip down blades on these. You can also add end plates. With both of those, it is like a box scraper. Can also add scarifiers in front of the rakes or use the scarifiers by themselves. The next most common implement I see are backblades. Lots of tillers and powered rakes, which may be called Harley rakes.
Myself, I don't have particularly rocky ground. In fact, my creek area is soft moist soil that has actually been muddy all summer due to all the rain. With all the loader work I have been doing in it, it has ruts and tracks and wheelspin holes all over it. I am puzzling over what implement to use to try to level and smooth it--rake, backblade, tiller, box, or whatever.
