What It Is

This is a complete 46-inch mower deck rebuild kit designed to replace worn spindles, blades, belts, and idler pulleys on select Cub Cadet, Craftsman, MTD, Troy-Bilt, and similar lawn tractors. It’s intended for restoring cutting performance on mid-sized residential decks, typically used on 1-3 acre properties.

Fitment & Compatibility

• Deck size: Only fits 46-inch cutting decks (measure your deck width before ordering).
• Models confirmed: Cub Cadet LTX1045, LTX1046, Craftsman LT2000, LT2200, Troy-Bilt Horse XP 46, and many MTD-built tractors with 46-inch decks.
• OEM cross-reference: Spindle 918-04865, Blade 742-04244, Belt 954-04129, Idler 756-04129. Verify your tractor’s original part numbers match these.
• Aftermarket note: Kit is aftermarket, not OEM. Check bolt pattern on blades (center hole and offset) and belt length (94.5” typical) against your originals.
• Critical check: Ensure your deck has three spindles (some 46” decks use two). Also confirm pulley diameter matches your old idler (usually 4” or 5”).

Key Things to Know

• Quality varies: Some users report aftermarket spindles wear faster than OEM. Inspect bearings and seals upon arrival; return if rough.
• Installation time: Expect 2-4 hours if you’ve done deck work before. Need a socket set, torque wrench (spindle bolts ~40 ft-lbs), and blade removal tool.
• Common gotcha: Belt routing is specific—check your deck diagram. Wrong routing causes poor engagement or belt slip. Kit may not include belt tensioner spring; reuse old one.
• Deck cleaning recommended: Remove old grass buildup before installing new parts to prevent imbalance and vibration.

Should You Buy It

Buy this kit if you have a compatible 46-inch deck with worn spindles or blades and want a single-purchase refresh instead of sourcing parts individually. It’s a solid budget option for DIY homeowners, but skip it if you prefer OEM longevity or need dealer support—aftermarket parts may not last as long under heavy use.
