Thank you to everyone who has commented. We did submit a claim through Kubota corrosion warranty, they denied the claim. I’ll paste the response below. I have asked the dealer to make it right: if it’s not Kubota‘s issue, it has to be the storage or transportation of the dealer.. I have done nothing to this tractor but store it out of the weather. It looks like they stored it this winter while doing warranty work next to the highway and it was exposed to multiple rounds of road salt. That’s the best case I can come up with. The right side is significantly worse than the left. I want them to replace the hose coupling hardware and valve components. Those ones could have some serious consequence if they fail. We’ll see what happens. Total bummer after spending 80k and treating this thing like a baby.
“to summarize, the KubotaLimited Warranty is intended to cover defects in materials or manufacturing within the specific timeframe for a machine. Based on what we see here, this is not something that will be covered by the Kubota Limited Warranty. The components shown with corrosion are manufactured at different facilities, which would indicate that this is not a manufacturing problem that occured at a single facility. Rather, this seems to be something environmentally that caused the corrosion. We would recommend that you reach out to (my dealer) Tractor to discuss the situation and the next steps.”
