Having an issue with GM 3100, after we mow 4 or 5 greens it starts to get slower and slower, hard to climb grades. In transport does not seem to be affected, all of my research pointing to a faulty valve bank or main pump. We have no way to test pump here and Toro wants over $400 to test. Can anyone give me any ideas on this one. What kind of tester is needed and about how much they cost. Almost ready to roll the dice on a rebuilt valve bank at $625.
