I searched around a little and didn't find them on Kubota's own site. As I think back, I believe Kubota made the manuals available through another company. I remember several times members here posted a photo of a manual page downloaded through the web. I sold my grass catcher to Junkman, who had a problem getting a screw to fit while reassembling it. I remember that Junkman went to a site and downloaded not only the manual, but the entire parts schematic for the grass catcher. I know that there are guys on here who know the address for this site. Sorry I wasn't able to find it.
