Thanks Wolfman. Sounds as reasonable as any other explanation. My reason for asking ... I was looking for a WSM that showed how to properly adjust the linkage on the boom/bucket control lever. I recently had a M7991 3rd function valve installed and the control lever is a little more "sloppy" than it was before. Anyway, I found a .pdf for the WSM on the LA1154EC. I will try emailing Kubota ... should be interesting ... if I get an answer at all.
Thank again!
