Yep, the shop manuals Jay mentioned are what you need.
Jay, I had an 1100 followed by the 1210. The 1100 was a good little basic tractor. It did lack the 4wd which I found was of great help plowing snow, pulling, and for ground engaging tools.
As far as the manuals for the 1210, they can be helpful, but for the approx. 18 years I had the 1210, I think pretty much everything was self-explanatory and the basics were covered pretty well in the Owners manual.
chefirv, You should be quite happy with your 1210, I liked mine for many years, it did a lot of work for me, and seldom needed any kind of repair.
Change the engine oil and filter, the fuel filter, and your tranny oil as directed, and it will take you a long way.
Enjoy.
