This is great! Don't know how I missed it - good information all around. Naturally, There isn't a manual for the T133S, but the others are similar enough that they should be a big help. ThomasTech, any chance of getting the T133S manuals up on the website? I've actually got a T133 'S' series Parts Manual and a V1903-B-Thomas-1-SI Kubota Engine Parts Catalogue, but am missing the service manual - it would be great if the service manual got posted. And, let me know if the manuals that I've got are missing from your Thomas Library, I could scan them and send them to you in an electronic format for posting with the others.
