What It Is

This is a complete deck rebuild kit for 46-inch cutting decks on select Cub Cadet, Craftsman, Troy-Bilt, and MTD lawn tractors. It includes three spindle assemblies, three blades, and all necessary hardware to replace worn-out spindles and blades in one go—designed for residential mowing, not commercial fleets.

Fitment & Compatibility

Check these before buying:

• Deck size: Must be exactly 46 inches. Measure your deck width from blade tip to blade tip.
• Model compatibility: Fits Cub Cadet XT1 LT46, XT2 LX46, RZT 46; Craftsman T240, T8200, T8600; Troy-Bilt 46xp, TB2246; and other MTD-branded 46-inch decks with similar spindle spacing. Verify your model number against the list.
• OEM part numbers: Replaces Cub Cadet 918-06977A / 618-06977A and 918-06977 / 618-06977. If your spindles use a different OEM number, this kit likely won’t fit.
• Spindle bolt pattern: This kit uses a 4-bolt spindle mount. Measure your existing spindle bolt hole pattern (center to center) to confirm it matches.
• Blade type: Blades are 15.5 inches long, 2.5 inches wide, with a 1-inch center hole. Cross-check with your current blades.

Key Things to Know

• Quality concerns: At 3.2 stars from 7 reviews, some buyers report premature bearing failure or bent spindles after light use. Inspect spindles for casting flaws before installation.
• Installation difficulty: Moderate. You’ll need a jack to lift the mower, a socket set, and a torque wrench (spindle nuts: 50-60 ft-lbs). Expect 1-2 hours for a first-time swap.
• Common gotcha: The provided hardware may not match all deck thicknesses—check that bolts are long enough to engage at least 3 full threads past the nut. Use thread locker on spindle bolts.
• Not a true OEM kit: This is an aftermarket set using generic spindles and blades. If you need exact OEM fit, buy genuine Cub Cadet parts individually.

Should You Buy It

Buy this kit if you need a budget-friendly, all-in-one refresh for a worn 46-inch deck on a residential Cub Cadet, Craftsman, or Troy-Bilt tractor, and you’re comfortable with moderate DIY and potential returns if fitment is off. Skip it if you want OEM reliability, commercial durability, or have a deck with non-standard spindle spacing—buy genuine parts instead.
