Mower Rebuild Kit for Cub Cadet 46" Deck LTX1045 LTX1046 LTX1046VT, Replaces for Spindle 618-04865, Idler Pulley 753-08171 956-04129, Blades 942-04244, 103" Belt 954-04219

What It Is

This is a comprehensive rebuild kit for the Cub Cadet 46-inch fabricated deck, designed to restore cutting performance on LTX1045, LTX1046, and LTX1046VT tractors. It includes two spindle assemblies, one idler pulley, two blades, and a 103-inch drive belt—everything needed for a full deck overhaul.

Fitment & Compatibility

Before buying, confirm your deck is the 46-inch fabricated (not stamped) model. The kit fits Cub Cadet LTX1045, LTX1046, and LTX1046VT, but also works on some other Cub Cadet models with the same 46-inch deck and 103-inch belt (e.g., GT1554, GT2000). Measure your belt length—it must be exactly 103 inches. The blades (942-04244) are 16.5 inches long with a 1-inch center hole and 0.25-inch offset; measure your existing blades to match. The spindles (618-04865) and idler pulley (753-08171/956-04129) are direct OEM replacements. If your deck has a different belt length or blade size, this kit won’t fit.

Key Things to Know

• Quality vs. OEM: Parts are aftermarket but match OEM specs. Spindle housings are cast iron, not stamped steel—durable but heavier. Some users report the blades are slightly thinner than OEM, so check for vibration after install.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench, and a jack to lift the mower. Plan 1–2 hours. The belt routing is tricky; take a photo before removing the old belt.
• Common gotcha: The idler pulley bolt may be seized. Use penetrating oil and a breaker bar. Don’t overtighten spindle bolts—torque to 30–35 ft-lbs.
• Warranty: No manufacturer warranty included. If your deck is under warranty, using aftermarket parts may void it.

Should You Buy It

Buy this kit if you’re doing a full deck rebuild on a 46-inch Cub Cadet with worn spindles, a slipping belt, or dull blades, and you want a single box solution. It’s a solid value for DIY owners who don’t want to hunt individual OEM parts. Skip it if you only need blades or a belt, or if your deck is a different size or brand.
