We regularly hear people say "take it to your dealer", or "it's under warranty, so call the dealer". To actually do any of that, what's involved for you? For me, it's a lot of work, a lot of $$, and a lot of time, so really it's the step of last resort. Here are some examples:
My Kubota dealer is 45min to an hr away. I could trailer my tractor or small excavator there, but that will consume roughly 6 hrs to get the trailer ready, load up, drive an hr (it will take the full hour pulling a heavy load), unload, drive home, and unhook and stow the trailer, then do it all again to pick the machine up once it's fixed. My larger excavator would have to be trucked, so I'd guess $500 each way, or $1000 total, and I can't get a tractor trailer in to my place, so I'd have to track the machine out to a location to meet the truck, which of course means the machine needs to work enough to move it around. And I'd still have to make at least one round trip to the dealer to go over the problem and make sure they know what's needed. So that's 3 hrs.
Then there is the actual dealer work. Most are very backed up, so a good chance your machine will sit for a week, if not multiple weeks before it's even looked at. Then any repairs will take at least another week because they will need parts and nobody seems to stock anything other than maintenance and common wear parts. And if their first "guess" at what to replace doesn't work, then you can stay another week while the guess again, and maybe again and again. And of course there is the possibility that the dealer won't be able to reproduce or actually fix the problem, and that you get the machine home and the problem still exists.
Mobile service is an option, but very expensive with billable travel and work time. But it is an option for spending $$ rather than spending your own time. But scheduling and time to repair isn't any better, and possibly worse.
The bottom line is that you will be out 3-6 hrs of personal work time, and up to $1000 in trucking, plus loss of use for weeks to months.
It's mostly the same for my Deere. The dealer is only about 20 minutes away which is a plus, but the tractor would have to be trucked. And from what I can tell they have zero direct experience with 6 series tractors, and only limited experience with 5 series.
All this is probably the biggest reason why I always end up doing work on the machines myself. It takes less of my personal time, and gets things running again faster.
