What It Is

This is a set of three mulching blades for 50-inch deck lawn tractors, designed to cut grass into fine clippings that decompose quickly. It fits select Cub Cadet, Troy-Bilt, Craftsman, and MTD models, and replaces OEM part numbers 942-05052A, 742-05052, 490-110-M155, 490-110-C155, 561558B, and CMXGZAM110155.

Fitment & Compatibility

Before buying, measure your existing blade length—these are 20.5 inches long with a 1-inch center hole and 0.25-inch thickness. They are specifically for 50-inch decks. Cross-check your mower’s model number against the OEM part numbers listed. These blades are aftermarket, not OEM Cub Cadet, but match the design and dimensions of the originals. They will NOT fit 42-inch, 46-inch, or 54-inch decks. Verify your spindle pattern (usually 3-point star or 5-point) matches the blade’s mounting hole pattern.

Key Things to Know

• Installation difficulty: Easy—just jack up the mower, remove the old blade bolts, and swap. Use a torque wrench to tighten bolts to 70-80 ft-lbs.
• Mulching vs. bagging: These are true mulching blades with curved surfaces to recirculate clippings. Not ideal for bagging or side-discharge use.
• Quality: Made from heat-treated carbon steel, but some users report they dull faster than OEM blades on sandy or rocky lawns. Expect 10-15 hours of cutting before needing a sharpen.
• Balance check: After installing, test spin the blade by hand—it should not wobble. Unbalanced blades cause vibration and damage spindles.

Should You Buy It

If you have a 50-inch deck Cub Cadet, Troy-Bilt, Craftsman, or MTD and want a budget-friendly mulching upgrade (three blades for $15), this is a solid value. It’s best for homeowners with average-sized lawns who don’t need commercial-grade longevity. Skip it if you bag or side-discharge often, or if your deck is a different size.
