Youxmoto 618-06976 618-06976A Deck Spindle 42 inch 918-06976 Fit for MTD/Cub Cadet XT1-LT42 XT2-LX42 CYT4220 SE Mower

What It Is

The Youxmoto 618-06976 deck spindle is a replacement part for the mandrel assembly that drives the mower blade on select MTD and Cub Cadet lawn tractors. It’s designed for 42-inch cutting decks, commonly used on residential XT1, XT2, and CYT series models.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck and uses OEM part numbers 618-06976 or 618-06976A. This spindle fits MTD-built Cub Cadet models including:

• XT1-LT42, XT2-LX42, CYT4220, SE series
• Also compatible with some Troy-Bilt, Yard Machines, and Craftsman 42-inch decks using the same spindle design.

Measure your spindle: Verify the shaft diameter (typically 5/8”) and overall length. Check the mounting bolt pattern (usually 3-bolt, 3.5” center-to-center). This is an aftermarket part—not OEM Cub Cadet—so expect slight differences in finish or paint, but dimensions should match.

Key Things to Know

• Build quality: Most buyers report it fits and spins smoothly, but a few note the bearings feel less durable than OEM. Inspect for wobble before final install.
• Installation difficulty: Moderate. You’ll need a socket set, a jack or blocks to lift the deck, and a puller for the old spindle (rust can make it stubborn). Replace all three spindles at once if others show wear.
• Common gotchas: The supplied lock washer may be too thick—reuse your old one if needed. Torque the center bolt to 30-40 ft-lbs; overtightening can crush the bearing housing.
• No grease fitting: This spindle is sealed and non-serviceable. If you want a greasable spindle, look for a different aftermarket option.

Should You Buy It

This spindle is a solid budget pick for DIY homeowners with a 42-inch Cub Cadet or MTD mower who want a quick, direct replacement without paying OEM prices. It’s not ideal for heavy commercial use or if you prefer serviceable bearings—but for typical residential mowing, it gets the job done at a fair price.
