Appendix A materials and parts list provides a baseline for identifying common components associated with the Cub Cadet 2072. Keep a stock of approved lubricants, coolants, and fuel with the correct specifications as listed by the manufacturer, and replace consumables at the recommended intervals. When ordering parts, use the exact model designation to ensure compatibility with the chassis, engine, and cutting system. Maintain a catalog of fasteners, including sizes, thread pitches, and tensile ratings, so replacements maintain the integrity of critical assemblies. For wear items such as belts, pulleys, and blades, adhere to the published service limits and inspection intervals to prevent performance degradation. Finally, store spare parts in a clean, dry environment and label all items clearly to facilitate rapid identification during maintenance and emergency repairs.
