What It Is

This is a complete 60-inch deck blade spindle kit designed for Cub Cadet Ultima ZT2, ZTS2, and ZT3 zero-turn mowers. It replaces the OEM part numbers 618-04822A, 918-04822A, 918-04822B, 742-05620, 742P05620, and 490-110-C187, providing a direct replacement for worn or damaged spindles that cause blade vibration or uneven cutting.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch deck—this kit will not fit smaller decks. It’s compatible with Cub Cadet Ultima ZT2 (all sub-models), ZTS2, and ZT3 series. Measure the spindle housing bolt pattern (typically 4-bolt, 3.5-inch center-to-center) and shaft diameter (should match your existing blade mount). If you have a different brand (e.g., Troy-Bilt, Husqvarna), check if the OEM numbers match—this is a direct replacement for those listed, not universal. Inspect your old spindle for bearing wear or shaft play before ordering to ensure it’s the root cause.

Key Things to Know

• Quality: Aftermarket kit with sealed bearings and a hardened steel shaft—comparable to OEM, but verify bearing preload and shaft alignment upon installation.
• Installation: Moderate difficulty; requires removing the deck, belt, and blade. You’ll need a socket set, torque wrench (specs: 35-45 ft-lbs for spindle bolts), and possibly a puller for seized spindles.
• Common Gotcha: The kit may not include new blade bolts or lock washers—reuse or buy separately. Check deck belt condition; a worn belt can cause premature spindle wear.
• Noise/Vibration: If your mower still vibrates after replacement, check for bent blades or a damaged deck shell—this kit won’t fix those.

Should You Buy It

If your Cub Cadet Ultima ZT2/ZTS2/ZT3 with a 60-inch deck has a noisy, wobbly, or leaking spindle, this kit is a cost-effective, high-rated replacement that matches OEM specs. It’s ideal for DIY owners comfortable with basic mechanical work and who want to avoid dealer prices. Skip it if your deck is smaller, your issue is blade-related, or you need a complete service kit (e.g., bearings and seals only).
