42" 60" Mower Deck Spindle Assembly 918-04822A 918-04822B Fits for Cub Cadet RZT 42 ZT1 60 ZTS2 60 ZT2 60 ZT3 60 cc30h LTX1040 LTX1042 Troy Bilt TB30 Super Bronco Pony Parts

What It Is

This is a replacement mower deck spindle assembly (OEM cross-ref 918-04822A / 918-04822B) that drives the blade on zero-turn and lawn tractor decks. Designed for 42" and 60" cutting decks on Cub Cadet, Troy-Bilt, and select MTD-built models.

Fitment & Compatibility

• Check deck size & model: Fits Cub Cadet RZT 42, ZT1 60, ZTS2 60, ZT2 60, ZT3 60, cc30h, LTX1040, LTX1042, and Troy-Bilt TB30, Super Bronco, Pony. Also fits many 42" and 60" MTD decks.
• Measure spindle housing: OEM spindle has a 1" diameter shaft (for standard 5/8" blade center hole) and a 3.5" mounting bolt pattern. Confirm your deck uses the same pattern—some older decks use a 3.25" pattern.
• OEM vs aftermarket: This is an aftermarket part, not genuine Cub Cadet. It typically matches OEM specs but may use a different bearing brand or slightly different grease seal.
• Check blade adapter: Some 60" decks use a flat blade mount; others use a splined or keyed adapter. This spindle uses a standard flat mount with a 5/8" hex bolt.

Key Things to Know

• Build quality: At ~$29, this is a budget spindle. It uses sealed bearings that are serviceable but not as heavy-duty as OEM ($50+). Good for homeowner use; less ideal for commercial mowing.
• Installation difficulty: Moderate. You’ll need a jack or blocks to raise the deck, a socket set, and a torque wrench (spec: 30-40 ft-lbs for spindle bolts). The hardest part is removing the old spindle—rust and corrosion often require penetrating oil and a breaker bar.
• Common gotchas: The spindle pulley may not match your original—check belt groove width (typically 1/2" or 5/8"). Also, the mounting bolts can be metric (10mm) or SAE (3/8"), so have both sizes ready.
• Bearing noise: Some users report bearing noise after a season. Grease fittings are present on some versions; if yours has them, grease annually to extend life.

Should You Buy It

This spindle is a solid, cost-effective fix for homeowners with a Cub Cadet or Troy-Bilt needing a quick deck repair. Avoid it if you mow commercially, need exact OEM fit for a tight belt alignment, or want a spindle that lasts multiple seasons under heavy use—spend more for genuine Cub Cadet or a premium aftermarket brand.
