What It Is

This is a replacement deck spindle assembly (2-pack) for 42-inch tractor riding mowers and 30-inch mini riders from Craftsman, Cub Cadet, and MTD. It drives the blade rotation on the mower deck and includes a tapped bolt hole and a grease zerk fitting for maintenance.

Fitment & Compatibility

• Deck size: Fits 42-inch decks (most common) and some 30-inch mini riders. Measure your deck width and spindle bolt pattern (usually 3-hole, 4-inch center-to-center).
• Brand/models: Replaces OEM part numbers 918-04822A, 918-04822B, 918-04822, 618-04822, and 918-04889. Works on Craftsman, Cub Cadet, MTD, Troy-Bilt, and Huskee models with these spindles. Check your mower’s model number (stamped under seat or on deck) against the part number.
• OEM vs aftermarket: This is an aftermarket replacement, not OEM. Confirm your original spindle has a tapped bolt hole (not a through-bolt) and a zerk fitting for grease. If your spindle uses a different bolt pattern or shaft size, it won’t fit.
• Measurements: Spindle shaft is typically 5/8-inch diameter, deck mounting holes are 3.5 inches apart. Verify before buying.

Key Things to Know

• Durability: Built with sealed bearings and a grease zerk for longer life. Grease every 10-15 hours of use to prevent bearing failure.
• Installation difficulty: Moderate. Requires removing the deck, blade, pulley, and old spindle. A socket set, torque wrench (blade bolt to 40-50 ft-lbs), and penetrating oil for rusted bolts are helpful. Expect 30-60 minutes per spindle.
• Common gotcha: The tapped bolt hole uses a 5/16-24 bolt (included). Do not reuse an old bolt with stripped threads. Also, ensure the spindle housing fits flush against the deck—some decks have a raised boss that may need filing.
• Fitment note: Not for zero-turn mowers or decks larger than 42 inches. Double-check your deck’s spindle spacing if you have a 30-inch mini rider.

Should You Buy It

If you have a 42-inch Craftsman, Cub Cadet, or MTD riding mower with a failing spindle (wobbling blade, loud grinding), this 2-pack is a solid value at $42.99. It’s a direct fit for the listed OEM numbers, includes the needed bolt and grease fitting, and the 4.6-star rating from 270 buyers backs its reliability. Best for DIY owners who can handle basic deck removal and don’t mind aftermarket parts. Avoid if you need an exact OEM match or have a non-standard deck.
