Congratualtions Bill. That's quite a feat. I guess you just about wore the seat out on that Kubota. I did just about the same thing in a 1.5a pond, in some really hard clay. I put 400h on my 29hp tractor, about 200h on my 35hp tractor. I would break up the clay 2-3" deep with a disk harrow, then push it up into piles and move it out. Prayers were answered when someone loaned me a 125hp Kubota and a JD650H dozer to finish the job. If not for the equipment loans, I would still be digging.

I began to get worried when I hit sandy clay, and because my neighbor's pond appears to leak. So I stopped 1-2 feet short of my original depth goal. Good luck with the sand!
