One of the guys I talked to has a scraper and a couple of dozers. He was thinking the scraper would do a pretty good job of packing -comparable to a sheep's foot. Is this accurate? Would this also do a quick job of moving clay from point A to B? The full area of the pond is a couple acres. Is this enough space for a scraper to move around efficiently? I don't know much about scrapers and have no idea what model/size the one he has is.
