Bought my first kubota new in 2006. Dealer was 45 min away. They had two stores. 45 min north of me, 45 min south of me.
Bout 5 years after I bought it, they opened up a store 10 min away. The guy that runs the new store was the delivery driver on my machine, and he remembered exactly who I was.
Early last year, I upgraded machines to a bigger kubota.
Neither have ever been back to the dealer, but I seem to find I call them about once a month. So being on a first name basis with the store manager of a good dealership is a nice thing.
While you may not need to ever take the tractor in, you need them for parts. Alot of the hydraulic filters are brand specific (dealer only or order online). I have had to replace a tie rod boot a few times, hydraulic oil if HST is a good thing to use your dealer for, I get replacement blades for my woods rotary cutter that I use for business, I had him e-mail me hydraulic diagrams out of the service manual when I installed my own remotes. Even though I wasnt buying any of the parts from them. When I made the deal to upgrade tractors last year, the machine was at one of their other stores. He had his delivery driver bring it down after closing, and he stayed well past closing time so I could load up that same day.
ETC ETC. The list goes on. A good dealer is a good thing to have in your back pocket.
Now if only kubota would make a ~60 PTO HP tractor, that has 20" front tires, AND is HST....I'd be all set for another upgrade.
