What It Is

This is a complete 46-inch deck rebuild kit for Cub Cadet LT1045, LT1046, and i1046 lawn tractors. It includes three spindle assemblies, two blades, two idler pulleys, and one belt, designed to replace worn-out deck components and restore cutting performance.

Fitment & Compatibility

• Deck Size: Fits 46-inch cutting decks only. Measure your deck width to confirm.
• Model Fit: Cub Cadet LT1045, LT1046, and i1046 series. Verify your model number on the tractor’s data tag (under seat or on frame).
• OEM vs Aftermarket: This is an aftermarket kit. OEM part numbers: spindles 618-0660/918-0660, blades 742-04125 (left) and 742-04124 (right), idlers 756-04129, belt 754-04118. Cross-check against your deck’s exploded parts diagram.
• Blade Check: The kit includes two blades—confirm your deck uses a two-blade, not three-blade, configuration. Blade length is 18.5 inches; measure your old blades.

Key Things to Know

• Quality: Rating 3.9/7 reviews suggests mixed durability. Some users report spindles failing faster than OEM. Inspect spindle bearings for smooth rotation before installing.
• Installation Difficulty: Moderate. Requires basic tools: socket set, jack stands, and possibly a puller for old spindles. Expect 2–3 hours for a first-timer.
• Common Gotchas: The belt may be slightly shorter than OEM—check tension after installation. Idler pulleys are plastic; replace with OEM steel if you mow heavy or wet grass. Blade bolts may need thread locker; torque to 40–50 ft-lbs.
• Deck Removal: You’ll need to remove the deck to access spindles and belt. Note belt routing before disassembly.

Should You Buy It

Buy this kit if you want a one-stop rebuild for a worn 46-inch Cub Cadet deck on a tight budget and are comfortable with moderate DIY work. Skip it if you prioritize long-term durability or have a three-blade deck; OEM parts or a higher-rated aftermarket set may be more reliable.
