I agree with most of this thread, but have to take issue with building a pond with a 60 hp (or less)tractor. How big of pond are you building and how much time do you have to dig it?

I've done tons of work (disc, plow, mow hay, bale hay, plow snow, etc)with an International Harvester 560 but don't think I would tackle building a pond with it. Just my $0.02.
