What It Is

This is a complete 46-inch deck rebuild kit for Cub Cadet LTX series lawn tractors (LTX1045, LTX1046, LTX1046VT). It includes two spindle assemblies, two pulleys, two idler pulleys, two blades, and one drive belt—everything needed to refresh a worn cutting deck.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Must be a 46-inch stamped or fabricated deck. Measure deck width edge-to-edge.
• Model number: Exact fit for Cub Cadet LTX1045, LTX1046, and LTX1046VT. Not for XT1, XT2, or RZT series.
• OEM cross-references: Spindles replace OEM 618-04865 / 918-04865; pulleys replace 753-08171; idlers replace 956-04129; blades replace 942-04244; belt replaces 954-04219. If your mower uses different part numbers, this kit won’t work.

Check your existing deck’s spindle bolt pattern and belt routing diagram—this kit assumes standard 46-inch Cub Cadet geometry.

Key Things to Know

• Quality: Aftermarket parts, not OEM Cub Cadet. Spindles and pulleys are generally durable, but blades may be slightly thinner than OEM. Expect 1–2 seasons of residential use.
• Installation difficulty: Moderate. Requires removing the deck, swapping spindles (including bearings), pulleys, idlers, and belt. Plan 2–3 hours with basic hand tools and a jack.
• Common gotcha: The belt may be slightly tight or loose on some decks. Check belt tension after install and adjust if needed. Also, the included blades may not fit all blade adapters—verify your adapter’s center hole and drive pin pattern.
• Missing hardware: The kit does not include bolts, lock washers, or spacers. Reuse original hardware or buy new grade-8 fasteners.

Should You Buy It

If your LTX1045/1046/1046VT deck has worn spindles (noise, wobble), shredded belts, or dull blades, this kit is a cost-effective one-stop refresh. It’s best for DIY owners who want to replace everything at once instead of piecemeal. Skip it if you need OEM-only parts or have a different deck size or model series.
