Re: John Deere X500 engine problem
Greetings. I know this thread is several years old, but I just found it, and I am having the same issues with a 3 year old X500 (with 21.8 hours on it) that I just purchased from a private party. I've changed the fuel filter, and inspected and washed the foam pre-filter on the air cleaner. The same symptoms. Runs for 20 minutes or so, and then goes into a surging routine before stalling. I also changed fuel (however all of my other gas implements seem to work fine with the gas). I've looked at the fuel cap, but I don't see any vent holes to clean out. Where are they? What am I missing. I think I have a year and a half of warranty to transfer, but if the fix is simple, I would prefer to DIY, rather than having to take the tractor to the Deere dealer 25 miles away. Any help will be appreciated.
