Exactly what I was thinking while digging my pond with a little Deere 650J.
While I was bouncing around in that dozer for days, I daydreamed about the quickest equipment (within reason) to dig 2-10 acre ponds. The earth is flat here, so they are 100% dug, no dams.
Big dozer (nothing digs faster)
Big wheel loader (nothing loads faster)
Big dump truck (maybe 2 or 3 of them!)
$600 a day fuel budget
