This is not racing related, but we are at wits end and don’t know what to do.

My buddy has a 8245R John Deere tractor that has suddenly started eating turbos. Tractor is still under warranty but John Deere ( neither the dealer or the factory) can figure out what’s wrong. He was planting wheat and the turbo went out they have put 3 more on it with no luck. After the factory tech put the last one on he made almost one complete round before it failed.

Do any of you guys have any idea what could be the cause, or where to start looking for the issue?

I have no experience with turbos so I’m lost on it.

not oiling correctly

yes there are other posibilities start there

What does "going out" mean exactly? Stop spinning, stop making boost, explosion, etc...

Are they Garret or Holset or ?
