I&T Shop Manuals have long been the trusted source for professionals and experienced mechanics. Originally published 40 years ago under the Intertec banner, each I&T manual covers removal, overhaul, installation and adjustment procedures of various assemblies and subassemblies. For maintenance items, in most cases, I&T Shop Manuals are intended to be used with the tractorâ??s original operatorâ??s manual.
