    I have a Exmark LZ26KC604 EFI 60" zero-turn mower - older 2002 model with low hours. It runs and mows great (800 hours), but when I go in reverse, it makes more noise than my other zero-turns. How do you know if the wheel motors are going out, or if is the hydro that is failing?

    But I'm guessing the OP has no hydro pump flow gauge or the specs of the pumps...

    What did you find was the cause of your squealing when in reverse? I am experiencing the same symptoms with my Toro Z-Master.
