What It Is

This is a complete mower deck spindle assembly kit for 42-inch cutting decks, designed for residential zero-turn and lawn tractors. It includes two spindle assemblies (918-04822A and 618-04822B), two blades (742-04308), and one belt (754-04060), making it a drop-in replacement for worn or failed spindles on Cub Cadet, Troy-Bilt, and similar MTD-built models.

Fitment & Compatibility

Before buying, confirm:

• Deck size: Must be exactly 42 inches. Measure deck shell width, not blade tip-to-tip.
• Models: Fits Cub Cadet RZT 42, LTX1040, and Troy-Bilt Pony 42, Bronco 42. Also compatible with MTD, Yard-Man, and Huskee models with the same 42-inch deck.
• Spindle bolt pattern: OEM-style with 3-bolt flange, 3-inch center-to-center. Not compatible with 2-bolt or 4-bolt spindles.
• Blade length: 15 inches (742-04308). Belt is 1/2-inch wide x 91.5 inches (754-04060). Verify your existing belt length—variations exist.
• OEM reference: This is an aftermarket kit, not genuine Cub Cadet. Fit may vary on decks with slight manufacturing changes (e.g., pre-2010 vs. post-2015).

Key Things to Know

• Quality: Rated 4.2 stars from 21 reviews. Most users report good durability for residential use, but some note bearings wear faster on heavy commercial jobs.
• Installation difficulty: Moderate. Requires removing the deck, unbolting the old spindle, and transferring the pulley. A socket set and jack or blocks are needed. No special tools.
• Common gotchas: The included blades may not be as sharp as OEM—consider upgrading separately. The belt may fit tight; verify routing before tightening. Spindle bolts can be seized—use penetrating oil and a breaker bar.
• Warranty: Typically 90-day limited. Check seller policy; some offer no returns if installed.

Should You Buy It

Yes, if you have a 42-inch Cub Cadet or Troy-Bilt lawn tractor or ZTR with worn spindles and want a complete, cost-effective replacement kit. It’s ideal for DIY homeowners who can handle a weekend install and don’t need commercial-grade longevity. Skip it if you require OEM parts for warranty or have a deck with non-standard bolt spacing.
