What It Is

This is a complete 46-inch deck spindle rebuild kit for Cub Cadet LT1045 and LT1046 lawn tractors. It includes three spindle assemblies (replacing OEM 618-0660/918-0660), three blades (replacing 177-2144/942-0644), and one drive belt (replacing 754-04153/954-04153) — everything needed to restore cutting performance on a single purchase.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch stamped steel deck (not a fabricated deck). This kit is designed for Cub Cadet LT1045 and LT1046 models built between 2005 and 2012. Also fits select Cub Cadet 1000, 2000, and 3000 series with the same 46-inch deck. Measure the existing spindle shaft diameter — it should be 5/8 inch. The belt is 1/2 inch wide by 92.5 inches long. If your mower uses a different belt length or shaft size, this kit won’t work. Aftermarket parts may have slight casting differences; check that replacement pulleys match your deck’s pulley alignment.

Key Things to Know

• Quality: Aftermarket spindles are generally solid but may have rougher finish than OEM. Grease fittings are included — pack bearings fully before install.
• Installation difficulty: Moderate. You’ll need a socket set, jack, and possibly a puller for stuck spindles. Expect 1-2 hours.
• Common gotchas: Blade bolts often rust — soak with penetrating oil the night before. Belt routing is critical; take a photo before removing the old belt. Spindle alignment must be exact to avoid belt throw.
• Blade sharpness: Blades come unsharpened; consider sharpening before first use for best cut quality.

Should You Buy It

Buy this kit if your Cub Cadet LT1045 or LT1046 has a worn, wobbly spindle or dull blades and you want a one-stop replacement with no extra shopping. It’s a cost-effective alternative to buying OEM parts separately, but skip it if you prefer genuine Cub Cadet parts or if your deck is a different size.
