Kubota parts availability can be gauged by their response to requests for parts for older models. I have a Kubota KF walk behind (purchased 1972). Can still get the odd part from Kubota Australia. Not all parts for the original B6000 (1974) are still available. American Kubota use different parts numbers to the rest of the world to try to make their models unique. This is an issue in getting spare parts for older models.
The best trick is to maintain the machine. Do not leave it outside in the weather. Change oil and filters regularly. Most seals, bearings and bushes are available at the local bearing shop.
