I had the same problem finding the extensions to use on my BX2822 snowblower and finally found what I thought was a similar snowblower with the extensions. One problem that we all face is that the terminology used by Kubota is "drift cutters" and they use the word interchangeably with the narrow flat pieces that stick up above the snowblower and the extensions that go on the sides of the snowblower. I finally did get a set of extensions that fit and will work, but they were not designed for my snowblower. I was ready to have a local shop cut and bend some steel and make them for me when I found these.
