I need to grade my yard (30,000 sq ft), and I don't know if I should use a skid steer with a bucket, or something else? I have heard and seen a rake attachement that drags behind the skid steer, but I wasn't sure if that was just for the finishing touches. We had a bunch of stumps when we moved in and I ground them so the yard has a bunch of humps and little valleys.

Thanks for any input!
