Oh yeah.. some thing you want to be careful about... be careful about what you post here.
The local Kubota warranty service rep figured out which customer I might have been since he was involved in my valve replacement - based on the content of the posts and the location in my profile. On another issue (PTO cams) he forwarded my posts to my selling dealer, identifying me. He also added a nugget of information pointing out that I was dealing with another dealer - which he had access to because I tried to get the PTO replacement done through an alternative dealer - and the same guy was the warranty rep there as well.
I never named my selling dealer in my posts as per etiquette but did point out that they were incompetent (over the valve and other issues). I had the dealer calling me at work and reaming me over the phone and threatening me with legal action for 'slander' - without realizing that none of the posts contained either my identity nor the dealers
So apparently, Kubota service reps have enough time and interest to read these forums but not enough to REALLY solve problems. I strongly suspect that TBNers like us are just an irritant to them and they would rather revert to a world where consumers were at the mercy of the dealer and companies they dealt with for knowledge about problems.
I'm not suggesting that anything anyone is saying here is incorrect. However, bear in mind that it can be used against you in the case of a 'goodwill' type of warranty repair.
Overall I think Kubota's products have a fantastic reputation but I think the company, at least the Canadian company, seems to operate more like a mom and pop shop, without concerns for etiquette or customer satisfaction. That is easy to do when their products are as good as there are because customers keep coming back regardless.
