This 600+ page service manual is for the CASE 730, 830, and 930 Series tractors. This manual was mostly made for Case mechanics and rarely given to consumers so it is very difficult to find now.
There are tons of diagrams, pictures, exploded parts views and troubleshooting in this manual. If there is any sort of problem with your tractor the solution is probably in this manual. This manual also includes three supplement and foldout pages that show enlarged diagrams.
Bonus: Also included is a free 200+ page service manual for the 930 series tractors and a 500+ page manual for the 730 and 830 series tractors. That’s over 1,400 pages of detailed information in total!
