The Ford 7710 I had used a PTO mounted pump, had a 25 gallon auxiliary tank, and ran a 4 foot cutter along with all the hydraulics it took to run the rear boom that was configured just like an extending backhoe arm. Rear PTO pumps can deliver a LOT of gallons per minute.
I also realize that the O/P is looking for a front mounted PTO pump, but as was brought up by others, a tank is also needed to cool the fluid. That may require an auxiliary tank mounted on the rear, which means it will act as a counterweight also. Putting the PTO pump back there will save just a little bit in mounting trouble and hose length.
