Does anyone have experience with PTO-driven pumps as a way to drain a pond? I have been unsuccessfully trying to siphon a shallow 1/3 acre pond for about 3 weeks now (my calculations show maybe 35,000 gallons or so). I am pretty sure I don't have a good 4 foot drop to the outlet and that is why it will siphon for a day or two, then stop.

I could try to remedy the lack of drop by buying more PVC, but it would mean getting another 100 feet length of it. If I am going to spend that kind of money, why not buy something that I may have other uses for.

I thought maybe since I have a tractor (35 hp) then maybe I could get more bang for my buck with a PTO-driven model? Any and all advice welcomed.
