I just wanted to post what I ran into with my Gator that ended up costing me way more to fix than it should have - hopefully it will give you something to check if you have the same issues.
I was out using the gator in my yard (transplanting trees), and I went to start it up, noticed it was running a little rough, and when I pushed the accelerator there wasn't much there - it would only go about 19 MPH with the pedal to the floor at around 4000 RPMs. It seemed to me like a fuel issue. After talking to my local John Deere service department they suggested a fuel filter replacement and clean out the fuel lines. I did this, with no change. I then decided maybe the fuel pump was going out - in hindsight I should have got a fuel pressure gauge to check it, but, again talking to my service department, they thought it was a logical step. Well, my gator had the old style pump, so you have to change everything - hanger, wiring harness, pressure regulator and pump - not a cheap fix! And to top it off, it didn't fix the problem. I broke down and took it in to the dealer instead of throwing hundreds of dollars at it and was surprised by the fix. Apparently they found a service bulletin that told them to replace the spark plug wires. They did that and it worked like a champ. The most expensive spark plug wire change I've ever had, but it works. Anyway - something to check, and apparently it is a known problem.
Good luck!
