8TEN Blade Spindle Kit for Cub Cadet Ultima ZT2 ZTS2 ZT3 60-Inch Decks 742-05620 918-04822B

What It Is

This is a complete blade spindle assembly for Cub Cadet Ultima ZT2, ZTS2, and ZT3 zero-turn mowers with 60-inch decks. It replaces worn or failed spindles that cause blade vibration, uneven cutting, or deck damage.

Fitment & Compatibility

Check these before buying:

• Deck size: Only fits 60-inch decks on Cub Cadet Ultima ZT2, ZTS2, and ZT3 models.
• OEM cross-reference: Replaces OEM part numbers 742-05620 and 918-04822B. Confirm yours matches.
• Physical check: Measure spindle housing height and bolt pattern. This kit uses a 5/8-inch shaft with a standard 3-bolt flange. If your deck uses a different bolt spacing or shaft size, it won’t fit.
• Aftermarket note: This is an 8TEN aftermarket part, not Cub Cadet OEM. It’s a direct fit for the listed models but verify deck model (e.g., 60-inch stamped or fabricated deck) before ordering.

Key Things to Know

• Quality: 8TEN spindles are generally reliable for residential use. Some users report slightly tighter bearing tolerances than OEM, which can reduce vibration.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, torque wrench, jack or lift). Expect 30-60 minutes per spindle.
• Common gotcha: The included bolts may be metric; your deck might use SAE. Check thread pitch before installing. Also, grease fittings are present—make sure to grease before first use and regularly.
• Warranty: Typically 1-year limited. Keep receipt and check seller’s return policy.

Should You Buy It

If you own a Cub Cadet Ultima ZT2, ZTS2, or ZT3 with a 60-inch deck and need a direct replacement spindle that won’t break the bank, this 8TEN kit is a solid value. It’s not for commercial use or odd deck sizes, but for residential mowing, it’s a reliable fix that saves about 30% vs. OEM.
