ILONPA (2 Pack) 918-06977 618-06977 Spindle Assembly - Fits 46 inch Mower Decks for Cub Cadet XT1-LT46 XT2-LX46 & for Craftsman T240 T225 T8200 T8600 T3100 T2800 - Replaces 618-06977A 918-06977A

What It Is

This is a replacement spindle assembly for the 46-inch mower decks found on many Cub Cadet and Craftsman lawn tractors. It houses the bearings that spin the blade, so if you hear grinding, wobble, or uneven cutting, this part is the fix.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: This fits 46-inch decks only. Measure your deck width to be sure.
• Model numbers: Works with Cub Cadet XT1-LT46, XT2-LX46, and Craftsman T240, T225, T8200, T8600, T3100, T2800. But it also fits many other tractors using the same MTD-style spindle.
• OEM cross-reference: Replaces 618-06977A and 918-06977A. If your original spindle has a different number, check the mounting hole pattern and shaft diameter (typically 5/8-inch shaft). Measure center-to-center bolt spacing—if it matches the originals, it’s likely compatible.

If your deck has three spindles, you may need two or three of these packs.

Key Things to Know

• Quality: Aftermarket, but rated 4.7/5. Most users report it’s solid and quieter than OEM spindles.
• Installation difficulty: Moderate. You’ll need a jack, socket set, and torque wrench. Expect 30–60 minutes per spindle.
• Common gotchas: The bolts that hold the blade pulley can be tight—use penetrating oil. Also, check that the blade aligns with the deck opening after install; a shim may be needed if it rubs.
• Warranty: No brand warranty mentioned, but the seller offers a 30-day return policy.

Should You Buy It

If you have a 46-inch Cub Cadet or Craftsman with a bad spindle and want a cost-effective fix that matches OEM performance, this is a smart buy. It’s not for commercial use or different deck sizes, but for DIY homeowners, it’s a reliable, well-reviewed replacement.
