What It Is

This is a 2-pack of 6-star mulching blades designed for 42-inch cutting decks on select Cub Cadet, Craftsman, and other lawn tractors and zero-turn mowers. The star-shaped cutting edge improves grass mulching and bagging compared to standard straight blades.

Fitment & Compatibility

Critical checks before buying:

• Deck size: Only fits 42-inch decks (not 46" or 54").
• Model range: Cub Cadet XT1, XT2, LT42, LX42, RZT 42; Craftsman T110, T120, T150 (42" deck). Also fits some Troy-Bilt, Husqvarna, and MTD models with 42" decks using the same spindle pattern.
• OEM cross-references: Replaces Cub Cadet 742-04126, 742-0616A, 742-0616, 942-0616; Craftsman 742-0616.
• Measurements: Blade length is 20.5 inches (center hole to tip), center hole diameter is 1 inch (round, not oval). Confirm your existing blade matches these dimensions. The star pattern is cut into the blade edge, not a separate attachment.
• Aftermarket note: This is an OEM Cub Cadet part, not a generic replacement, so fitment is exact for listed models.

Key Things to Know

• Mulching quality: The 6-star design produces finer clippings than standard blades, but works best when you mow frequently and keep blades sharp.
• Installation: Requires a torque wrench – tighten to 70-90 ft-lbs. Use thread-locker if your spindles are aluminum. The star pattern is directional; ensure the cutting edge faces the correct rotation direction (usually counterclockwise when viewed from above).
• Durability: OEM steel is harder than most aftermarket blades, but these are not “lift” blades – they won’t throw clippings as far side-discharge. Expect 25-50 hours before sharpening.
• Common gotcha: The 1-inch round center hole will not fit older decks with 5/8-inch or 7/8-inch oval holes. Always measure your existing blade’s hole and length before ordering.

Should You Buy It

Buy these if you own a Cub Cadet or Craftsman 42-inch deck and want OEM-quality mulching blades that deliver finer clippings and better bagging than universal replacements. They’re a direct fit with no modifications, and the two-pack is priced competitively for the brand. Skip them if you need lift blades for side-discharge or have a different deck size.
