I have 2002 Scag Turf Tiger that has a hydro drive that has gone bad. My dealer is in the process of tearing down the wheel motor to see how much damage has been done to it. Fortunately I stopped using it as soon as it started making noise. He tells me that Scag has had some problems with their hydro drives. This same drive was replaced a few months after I purchased it. I have relatively low hours on my machine less than 400 hours and just a little over 3 seasons of use. Has anyone else had any experience with premature hydro drive failure? This repair may cost upwards of $700 if Scag does not take some responsibility.
