JD 4320
My dealer called me today to set up an appointment to replace the computer on my 4320. He said that John Deere approved the replacement. It's not a recall, but rather a product improvement and that it would improve the machine's performance and fuel usage. The tractor is about a year old. I thought it was odd that I haven't received any official JD correspondence relating to this matter. Anyone experience anything similar?

No, but I would be very interested in the result. I've got a 4520, and if they are swapping computers for free, there has to be a good reason...

I called a few dealers today and none of them had heard anything about the replacement, so I decided to call JD instead. It turns out that some 4000 series machines with particular serial numbers have a problem with losing power. I couldn't get any more details, but I found out that the solution was to replace the computers in the effected machines. I guess the fact that only some machines were effected is what made the whole issue kind of mysterious. I still need to find out why I never received notification of this issue directly from JD.

Nice job tracking down the extra details Zinno, did the guy from JD give you a serial number range that they expect to be impacted? I'll bet a whole lotta guys would want to know that, since it would give us a quick way to know if we need to take our machines in...

Thanks, Chet.
