What It Is

This 46-inch mower deck rebuild kit includes two spindles, two blades, one belt, and two idler pulleys, designed to refresh the cutting deck on select Cub Cadet and Craftsman lawn tractors. It’s ideal for restoring cutting performance and eliminating vibration or uneven cuts on mid-to-large residential lawns.

Fitment & Compatibility

Before buying, verify your mower has a 46-inch stamped steel deck (not fabricated). This kit fits Cub Cadet XT1-LT46, XT2-LX46, and Craftsman T225, T240, T2800, T3100, T8600 models. The spindles (918-06977A) replace OEM part 918-06977, blades (942-04244A) are 18.5 inches long with a 1-inch center hole and 0.25-inch offset, the belt (954-05022A) is 149.5 inches long (Kevlar-reinforced), and idlers (756-05034A) are 4-inch diameter with a 5/8-inch bore. Cross-check your mower’s model number (under seat or on frame) against the listed series—older or non-standard decks may require different parts.

Key Things to Know

• Quality: Aftermarket parts are generally durable, but spindles may use lighter-duty bearings than OEM; expect 2-3 seasons of typical residential use.
• Installation: Moderate difficulty. Requires basic tools (wrenches, socket set, jack/ramps). You’ll need to remove the deck, replace each component, and re-tension the belt—allow 1-2 hours.
• Gotchas: The blades may need balancing after install. The belt routing diagram is critical—misrouting causes premature wear or poor engagement. Check spindle housing for cracks before installing; a bent housing will ruin new bearings quickly.
• Missing hardware: Kit does not include blade bolts, lock washers, or spindle mounting bolts—reuse or replace separately.

Should You Buy It

Buy this kit if your 46-inch Cub Cadet or Craftsman is 3-5 years old, blades are dull, spindles are noisy or wobbly, and the belt is frayed. It’s a cost-effective way to restore cutting quality for about $125, but skip it if you need OEM-grade bearings for heavy commercial use—those require separate, pricier spindles.
