It being a Japanese tractor, I would probably check with a Kubota (or any other Japanese brand) dealer mechanic as a starting point. Some of the components on Yanmars, Kubotas, and other Japanese brands are interchangeable. I understand that some of the Bolens are made by Iseki. And as I write this I recall waiting 2mos. last summer for some very common Kubota parts, covid I was told.
