What It Is

This is a complete combo kit for Cub Cadet LT1045 and LT1046 lawn tractors, containing a 46-inch deck spindle assembly, two OEM-style blades, and a 122-inch by 1/2-inch deck belt. It’s designed for replacing worn or broken deck components in one go, saving you from buying parts separately.

Fitment & Compatibility

  • Deck size: Fits only 46-inch cutting decks—check your mower’s deck measurement (not the tractor model alone).
  • Model fit: Directly fits Cub Cadet LT1045 and LT1046; also compatible with some other Cub Cadet models using the same deck (e.g., LT1042, LT1050 with 46-inch deck). Verify your deck part number.
  • OEM vs aftermarket: This is an aftermarket set, not genuine Cub Cadet. Check that all included part numbers match your originals: spindles (618-0660, 918-0625B, 918-04137, 618-04137, 618-0625), blades (742-04125, 742-0644), and belt (754-04153, 954-04153). Cross-reference your tractor’s parts diagram.
  • Measurements: Belt is 122 inches long x 1/2 inch wide. Blades are 46-inch deck compatible (typically 16.5 inches long, but measure your old ones). Spindle shaft diameter should be 5/8 inch—confirm before buying.

Key Things to Know

  • Quality concerns: With only 4 reviews at 4.3 stars, reliability is not well-established. Some users report early belt wear or spindle wobble—inspect all parts upon arrival for defects.
  • Installation difficulty: Moderate. You’ll need basic tools (socket set, jack, and possibly a puller for old spindles). Expect 1–2 hours if you’ve done deck work before; longer for first-timers. A torque wrench is recommended for spindle bolts (around 30–40 ft-lbs).
  • Common gotchas: The belt may be slightly tight or loose on some decks—check routing carefully. Blades are universal but may need balancing. Spindle bearings are sealed; don’t grease them.
  • Warranty: Typically no manufacturer warranty on aftermarket kits—buy from a seller with a return policy.

Should You Buy It

Buy this kit if you need a budget-friendly all-in-one replacement for a worn 46-inch Cub Cadet deck and want to avoid buying parts separately. It’s best for DIYers comfortable with moderate mechanical work. Skip it if you prefer OEM reliability or have a different deck size—verify fitment meticulously first.
