What It Is

This is a complete spindle and blade rebuild kit for 50-inch mower decks, designed to replace worn spindles and blades on Cub Cadet, MTD, and Toro zero-turn and lawn tractors. It includes three spindles, three blades, mounting hardware, and gloves—everything needed for a full deck overhaul.

Fitment & Compatibility

Check these before buying:

• Deck size: Fits only 50-inch decks (not 46", 54", or 60").
• Model fit: Confirmed for Cub Cadet RZT50, i1050, SLT1550, LTX1050, and compatible MTD/Toro models with OEM part numbers 618-04126, 918-04126, 742-04053, 942-04053.
• Spindle shaft: Measures 1-inch diameter with a 5/8-inch shaft length; verify your deck’s spindle hole size matches.
• Blade specs: Each blade is 16.5 inches long, 2.5 inches wide, with a 1-inch center hole and 5-point star pattern—measure your old blades to confirm.
• Aftermarket vs OEM: This is an aftermarket kit; if you need exact OEM fit, cross-reference your model’s parts diagram first.

Key Things to Know

• Installation difficulty: Moderate. Requires basic tools (socket set, wrenches, possibly a puller for stuck spindles). Expect 1–2 hours for all three spindles.
• Build quality: Spindles are cast iron with sealed bearings—should match OEM durability. Blades are heat-treated steel but not as thick as premium OEM blades (0.1875" vs 0.25" on some OEMs).
• Common gotcha: Spindle bolts are often rusted or seized. Have penetrating oil and a breaker bar ready. Also, the kit includes gloves but no spindle removal tool—you’ll need one if your spindles are stuck.
• Warranty: No explicit warranty listed; check seller return policy before ordering.

Should You Buy It

Buy this if you need a complete spindle and blade swap on a 50-inch Cub Cadet RZT50 or similar MTD/Toro model and want a single, affordable kit rather than sourcing parts separately. It’s a good value for DIYers comfortable with moderate mechanical work, but skip it if you need extreme blade durability (e.g., heavy mulching or commercial use) or exact OEM fitment without cross-checking.
