If you are going to go out a buy a pump for this application, get the 2
speed version. The automatic downshift is much kinder to a gas engine
setup.

Roy,
Thank you for helping out a hydraulicly challenged individual! I
really appreciate you taking the time to explain this. I racked my
brain with a couple books and a Surplus Center catalog as a refrence
and tried all different formulas, but I had no way of knowing if I was
even in the ballpark. (I kept coming up with one pump they had that was
4GPM, but calculated that is would be closer to 5.4 GPM with the engine
speed.) Thanks again for your help,
Craig
