I was thinking of a PTO pump, but concluded that since I have electric relatively close to my pond, it would probably make more sense to buy an electric pump and save tractor hours.
Harbor frieght and Northern Tool both have such pumps for sale at $100 or less, I'm pretty sure.
Someone about a month ago posted about using a similar pump for the same purpose...and included a couple pics...I want to think it was Von, but I am pretty sure it was Larry...with the pond and the dozer that he had stuck for a while, but while I remember his smile and his posts...I forget his tbn name... /forums/images/graemlins/blush.gif
