What It Is

This is a replacement spindle assembly for 42-inch MTD, Cub Cadet, and Troy-Bilt lawn tractor decks. It houses the blade pulley and bearings, enabling the mower blades to spin and cut grass.

Fitment & Compatibility

• Deck size: Fits only 42-inch cutting decks (measure your deck width before ordering).
• Machines: Works with Cub Cadet XT1 LT42, XT2 LX42, XT1-LT42, XT2-LX42, KH, KW, CYT4220, and similar MTD-built models.
• OEM cross-reference: Replaces OEM part numbers 918-06976A, 918-06976, 618-06976, 618-06976A. Check your current spindle’s stamped number.
• Physical check: Measure the spindle shaft diameter (typically 5/8-inch) and bolt pattern to confirm. Aftermarket part, not factory OEM.

Key Things to Know

• Bearing quality: Some users report bearings last 1–2 seasons under heavy use. Consider upgrading to OEM if durability is critical.
• Installation: Moderate difficulty—requires removing the deck, belt, and blade. Have a torque wrench; spindle bolts need 30–40 ft-lbs.
• Common gotcha: The spindle may not include a new pulley or blade adapter. Reuse your old pulley if compatible, or check condition before starting.
• Pack size: This is a 1-pack. If your deck has three spindles, you’ll need to buy multiple units.

Should You Buy It

Good for budget-conscious owners of 42-inch MTD/Cub Cadet tractors who need a quick, functional replacement. Skip if you want OEM longevity or have a different deck size.
