My opinion of Kubota customer service at KubotaUSA has dropped dramatically. It appears, that while they invited continued questions regarding my initial request, that they have forced closed the 'event'. Here is what they said after my second request:
"Recently you requested personal assistance from our on-line support center. Below is a summary of your request and our response.
We are continuing to work on your issue. To update your question with additional information, please respond to this email."
I had responded with further clarification of my requests and asked for information, and got no response. SO I resubmitted another clarified request, to which I received the following reply:
"Subject
Replacement turf tire [Incident: 200529-000011] Kubota B7300
Response
To submit a new incident for Kubota Customer Care, please visit our support site:

So much for responding to their email at the address that they clearly indicated.
I agree with other users, and now believe that KubotaUSA is just ignoring or deflecting any and all requests for technical information.
While I really like my B7300, it appears that it is a truly orphaned machine and I and other owners are on our own. It truly does not make me really want to use a KubotaUSA or a Kubota dealer for anything.
