Even a small pull type scraper behind a farm tractor is going to out perform a track loader or dozer at those distances. My uncle built a good sized pond with just that, about 10,000cy went into the dam. Main earth moving equipment was a 5yd scraper behind a 150 horse Allis Chalmers 8050, powershift transmission and FWA. Tractor would easily boil dirt over the top of the scraper, loaded and hauled quick.
