Thanks everyone for the replies. Scaper is it, but it doesn't look like it is whole lot of cheaper than a dozer. But it is cheaper than a dozer and a dump truck. I lucked out, and this year's dirt will be placed relatively close to where it comes from. My next pond, in couple of years, will be a different story. It looks like it may be worth buying a used dozer. I guess I better learn how to put together thrown tracks.
