The pto pump on my F11A gave up the ghost - it was not original to the loader, someone over the years put this one on (didn't even look like a farmhand pump). It was too small to begin with, therefore making the loader very slow. Now I am looking to put on a REAL pump - the question is, what gallon per minute output should I be looking for? The local AGCO/Farmhand dealer was of no help, had no idea other than a $700 price tag, which is more than I plan on spending. I"ve got the st"d F11 oil reservoir, which I think is about 5 gallons, and I read that the reservoir should be twice the gpm output. If that"s the case, then I"m limited to 2 1/2 gpm??? Any comments, opinions from all of you is appreciated.
