I have about a half acre where I need to remove some rocks. I just brought in a bunch of fill and would like to pick the rocks prior to planting. I leveled it using the father in laws L4330. Now I have my B7510 to finish. I've been going over the ground with the box scraper teeth down and a harrow trying to bust up dirt clods and find rocks. I have been picking up big rocks by hand, but would love it to be a bit cleaner. I thought about hiring the neighbor kids, but though that maybe a rock rake might do the trick
