Why This Parts Catalog Matters

When you are working on a 40-year-old tractor, the difference between a job done right and a job done twice often comes down to having the correct part number. This catalog eliminates guesswork. Each exploded diagram is keyed to a part number table that specifies the exact component, quantity, and application notes. Whether you need a single bearing for a front wheel hub or a complete hydraulic lift cover assembly, the catalog gives you the factory part number to search, cross-reference, or order with confidence.

Unlike generic aftermarket references, this catalog reflects the actual production parts used across the 6600 and its sister models from 1975 through 1981. The detailed diagrams show how components assemble, which is invaluable when you are disassembling a complex system like the dual power transmission or the front wheel drive transfer box. And because it covers multiple models, you can often find shared components that interchange between tractors.
