Well, third post, and I am now a new MTD 990 owner (my 1st tractor.) My thanks to Benn, I will take good care of it. The MTD website is a great resource but finding manuals sucks. I did a fairly detailed and lengthy search to come up with manuals for the attachments and thought I would put up the links to each model year tractor as well, just for completeness. I hope you find this useful.
edit: I messed up the links and will fix...

Reason: links are broken
54” Snow Blade (Quick Attach style) http://manuals.mtdproducts.com/mtd/DocGetter?doc=770-8150%20r8202.pdf --- ok, this still doesn't work because of URL encoding issues. The filename that MTD uses does not have an underscore (between 8150 and r8202), it uses a space, however, Hex-code %20 does not appear to generate a space within a URL within this forum, so you will have to manually edit the link once you click on it. Just delete the underscore and use a space instead. ----
Also thought I would add this fantastic thread by blackknight "990 Snow Plow Build for my 81 MTD" It has full drawings with measurements! 990 Snow Plow Build for my 81 MTD
