I'm Mike Georgia. I'm the Rototillerguy and landscaper here in Southern California. What we're doing is we're just shaving. We're not digging down with any earnest, we're not trying to get down into the soil yet. We're just shaving the unwanted material off the top surface. So this is, we're just in an effort to remove what we don't want in our area. We've shaved off the top, but now we're shoveling it, and we're moving it out of the soil area. So, you do as diligent a job as you can here, and then you're just constantly taking out the little bits that are left on the surface. You're just raking them off and taking them off as well.
