What It Is

This 46-inch deck rebuild kit includes two spindle assemblies (618-04636), two idler pulleys (753-08171), two blades (942-04244), and a 103-inch belt (754-04219). It is designed to replace worn-out cutting deck components on select Cub Cadet, Troy-Bilt, MTD, and Yard Machines tractors, restoring blade rotation and belt tension.

Fitment & Compatibility

Check these before buying:

• Deck size: Only fits 46-inch stamped steel decks. Measure blade tip-to-tip or check your deck’s stamped model number.
• Brand/model: Compatible with Cub Cadet LTX1045, LTX1046, LT2000, LT2200; Troy-Bilt Pony, Horse XP; MTD 46-inch decks. Not for zero-turn or fabricated decks.
• OEM cross-reference: Spindle 618-04636 replaces OEM 918-04636; idler 753-08171 replaces OEM 918-08171; belt 754-04219 replaces OEM 954-04219. Aftermarket parts may differ slightly in bearing quality or belt length.
• Measure your belt: The 103-inch belt is a specific length. If your deck uses a different belt (e.g., 100-inch), this kit will not fit.

Key Things to Know

• Quality: Aftermarket spindles and idlers work fine for residential use but may wear faster than OEM under heavy or wet grass conditions. Blades are standard 46-inch replacements.
• Installation difficulty: Moderate. Requires removing the deck, swapping spindles, idlers, and belt. You’ll need a socket set, pry bar, and possibly a puller for stuck pulleys.
• Common gotcha: Spindle housings may be slightly taller than OEM, causing blade-to-deck clearance issues on some decks. Check blade height after installation.
• Belt routing: The 103-inch belt is a single belt design. Verify your deck uses only one belt (some models have a separate drive belt). Incorrect routing can cause slipping or premature wear.

Should You Buy It

This kit is a solid value if your deck needs multiple worn parts replaced at once, saving time and shipping costs. It’s best for DIY homeowners with a 46-inch Cub Cadet or Troy-Bilt tractor who want a complete refresh rather than piecemeal repairs. If you demand OEM longevity or have a commercial-use mower, consider buying genuine Cub Cadet spindles separately.
