Thanks to all who responded to my initial post, I apologize for not responding to anything earlier but with the holidays and all, things have been extremely busy to put it mildly.
As for a follow up, I wound up borrowing a trailer and taking my CK3510 to the dealer. I arrive just as they opened, as arranged. When I backed up to their service bay, They brought out their Kioti diagnostic kit, pulled the codes, cleared the CEL, and reprogrammed the tractor without it ever leaving the trailer. Fifteen minutes from start to finish.
As it was covered under the warranty, I didn’t get charged anything.
I asked the mechanic what the problem was and the young man told me “…one of the programs had corroded. I pulled it out and replaced it…” (Corroded, so you pulled it out and put in a new program?...I’ll let you work on my tractor while it’s under warranty, but I think you’ll stay away from my computers…)
He went on to say the problem might have been due to the cold, and he’s only ever seen that particular code twice.
It’s been a week (of even colder weather – with daily use) and so far, so good.
I do understand time, fuel, wear and tear on service trucks, etc. are not free. And I understand the dealer has to make a profit.
But, I am not impressed with the idea of a service charge of over $700 for something that turned out to be a software fix – while under warranty. And for that being a minimum charge -on top of anything else- once it's out of warranty. I suppose it's my excuse to buy a trailer that can haul the tractor.
I’m just glad the tractor is back into daily operation, and all it cost me was $70 bottle of whiskey I gave as a ‘thank you’ to the guy I borrowed the trailer from.
