850 California: best source for workshop and technical manuals

Hi all

I’ve just got hold of a ‘79 850 Cali and looking for a suitable workshop manual, there are several sources out there. Has anyone procured one recently and can you recommend a source - preferably in English!?

Thanks and all the best.


Greg Bender’s site this old tractor is a good source


Haynes do a manual.

Thanks folks, I’ve navigated to the right part of Greg’s site now.

Guzzitek have plenty of manuals, parts books as well.
