Long before modern diagnostics and tablet-based service tools, mechanics relied on something simple and rugged: I&T Shop Service Manuals. For over 75 years, I&T manuals have delivered clear, mechanic-focused guidance for maintaining and repairing tractors and agricultural equipment—combining professional-level detail with real-world usability. Now owned by Clymer and Haynes Manuals, these manuals continue to uphold their legacy as a staple in the farm shop and service bay.
A Legacy Born in America’s Heartland
Founded in 1948, I&T (Interstate and Tractor) Shop Service Manuals were created to meet a growing demand: simple, reliable repair instructions for farm equipment. At the time, manufacturers’ service documents were often overly complex, incomplete, or unavailable. I&T filled that gap with affordable, easy-to-follow books designed for working mechanics and farmers, not engineers.
These weren’t just parts catalogs or theory—they were hands-on service guides written by technicians, made for the person turning the wrench.
