What It Is

This is a complete spindle rebuild kit for 46-inch cutting decks on certain Cub Cadet, Craftsman, and MTD lawn tractors. It includes two spindle assemblies (housing, bearings, shaft, pulley) and two blades, enabling replacement of worn spindles and blades in one purchase.

Fitment & Compatibility

Before buying, verify your mower’s deck size is exactly 46 inches. This kit fits Cub Cadet XT1-LT46, XT2-LX46, Craftsman T240, T225, T8200, T8600, T3100, T2800, and many MTD models with a 46-inch stamped deck. Cross-check your OEM spindle part numbers: 618-06977, 918-06977A, 618-06977A. Blade numbers are 742-04244 and 742-04290. Measure your existing spindle bolt pattern (typically 3-bolt, 3.5-inch center) and spindle shaft diameter (usually 5/8-inch). If your deck uses a different bolt pattern or shaft size, this kit won’t fit.

Key Things to Know

• Installation difficulty: Moderate. Requires basic tools (socket set, torque wrench, jack/stands). Expect 1-2 hours per spindle.
• Quality: Aftermarket parts, not OEM. Most users report good durability, but bearings may be slightly less robust than factory Cub Cadet spindles.
• Common gotchas: The included blades may need balancing before use. Spindle pulleys may require thread-locker on mounting bolts. Check that your deck’s belt routing matches the spindle pulley diameter—some aftermarket pulleys are slightly different.
• What’s not included: New spindle bolts, lock washers, or grease. Reuse OEM hardware if in good condition, or buy separately.

Should You Buy It

This kit is a solid value if you need both spindles and blades for a 46-inch deck on a compatible Cub Cadet or Craftsman tractor. It’s best for DIY owners comfortable with moderate mechanical work who want a single-kit solution. If you prefer OEM parts for maximum longevity, buy genuine Cub Cadet spindles separately. Skip this if your deck has unusual bolt patterns or you need only one spindle.
