Quick site review... Beach Ball / Basket ball sized boulders 50% content, nice rich dirt in between boulders, (but very little dirt, as you keep popping up beach ball sized boulders) - owner just wants it flat enough to mow, not necessarily lawn quality, just ez'r to maintain than the boulder field. He plans to hydro seed. We used a D8 to split ~ 20 stumps (of 6' dia trees) and then graded off ~ 1' ft, then brought the dirt back across with a Case 650G 6-way, while I was sorting the rocks with the grapple I modified the forks (to 4" spacing) to my Grapple for sorting the basketball and football sized stuff, Got about 60 yds of them ~ 1acre (buried 20 yds), and it's not too bad, but plenty of 4" and below plus larger, but skinnier that fell through the grapple. so whats left? boulders floating just below the surface (been back bladed with the 6way, so they are flush with surface, but below. NOW.. to get the smaller rocks out (without hand picking 1 acre) Can I rent something that will work? I've never used or seen a Rockhound up close, do they have ability to work in soils that include the big rocks near the surface? (Spring teeth?) A rock rake on a tractor tends to get hung up on the buried boulders, and ends up hacking up the back bladed surface pretty bad. Suggestions?
