Had some injector issues at about 1800 hrs. Replaced 2 (under warranty), then at 2200 hrs had to replace the other 2 (also done under warranty). This fall, had some more issues at 2700 hrs, and had to replace another one. I was pretty confident there was a second one failing at this time, but the mechanic was not as sharp as my normal guy, and couldn't figure out for sure which one, so I only got 1 replaced. Then, after claiming that he could see sediment in the bottom of the filters, and the bottom of the fuel tank, he insisted we drain everything and flush. Also at this time, he discovered I had accidentally installed a secondary filter in the primary filter housing, but the secondary had the proper filter. He documented this in his report, and obviously Case denied the claim. The bill for the service call and work was $3600. After going around and around with our dealer a few times, our territorial service manager got us a large credit on the bill. After that, I ran several tanks of fuel with Deere Fuel-Protect injector cleaner, and now I feel it's running as good as it did when new. I'm at 3200 hrs right now. Other than the injector issues, I haven't had any problems.
