What It Is

This is a complete deck rebuild kit for 50-inch cutting decks on select Cub Cadet and MTD lawn tractors, including the LTX1050KH, LTX1050VT, and SLTX1050 models. It includes three spindles, two idler pulleys, three blades, and a drive belt—everything needed to refresh a worn-out deck in one purchase.

Fitment & Compatibility

• Deck size: Only fits 50-inch stamped steel decks (not fabricated or 46/54-inch decks).
• Model check: Confirmed for Cub Cadet LTX1050KH, LTX1050VT, and SLTX1050. Also fits some MTD-built tractors with the same deck—verify your model number on the deck tag (not the tractor frame).
• OEM vs aftermarket: This is a non-OEM kit. Spindles (618-04825, 918-05016, 918-04825) and idlers (753-08068A, 753-08171) are aftermarket replacements. The belt (754-04240/954-04240) and blades (742-04053) match OEM specs.
• Measurements: Confirm spindle bolt pattern (typically 3-bolt, 3.5-inch center) and blade length (18 inches) before buying. If your deck uses a different spindle or blade, this kit won’t fit.

Key Things to Know

• Quality varies: Spindles are often aluminum housings with steel bearings—adequate for residential use but not as durable as OEM steel spindles for heavy commercial mowing.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, torque wrench, jack or lift) and about 2–3 hours. Removing old spindles can be the toughest part if rusted.
• Belt routing: The belt (954-04240) is a longer replacement for some OEM belts; check your deck’s belt diagram before installing. Routing errors cause poor blade engagement.
• Blade balance: Aftermarket blades may need balancing before installation. Unbalanced blades cause vibration and premature spindle wear.

Should You Buy It

Buy this kit if you have a 50-inch Cub Cadet LTX-series or compatible MTD tractor and want a single-purchase rebuild for light to moderate residential use. It’s a cost-effective way to replace all wear parts at once—but if you mow heavy grass daily or want OEM-grade longevity, consider sourcing individual OEM spindles instead.
