942-04385 742-04385 30 Inch Mulching Mower Blades 2 Pack Compatible with Troy-Bilt TB30 TB30R, Cub Cadet CC30 CC30H, Craftsman R1000 RER1000 R1500 Rear Engine Riding Mowers, 6 Point Star Center Hole

What It Is

This 2-pack of 30-inch mulching blades (part #942-04385 / 742-04385) is designed for rear-engine riding mowers from Troy-Bilt, Cub Cadet, and Craftsman. They replace OEM blades to finely chop grass clippings for nutrient recycling, ideal for frequent mowing without bagging.

Fitment & Compatibility

Check before buying:

• Deck size: Only fits 30-inch cutting decks—measure your deck width if unsure.
• Model compatibility: Confirmed for Troy-Bilt TB30/TB30R, Cub Cadet CC30/CC30H, Craftsman R1000/RER1000/R1500. Other rear-engine riders with 30-inch decks may work if they use a 6-point star center hole.
• Center hole: 6-point star pattern—measure your spindle’s star shape to confirm match. This is not a standard round hole.
• OEM cross-reference: Cub Cadet OEM #942-04385 (sold as 742-04385 in some packages). Aftermarket, so verify your current blade’s part number.
• Length: 30 inches tip-to-tip—measure old blade or deck to avoid clearance issues.

Key Things to Know

• Quality: Aftermarket steel, likely thinner or less balanced than OEM Cub Cadet blades. Check for warping before install.
• Installation: Moderate—requires removing the deck or tilting the mower. Use a torque wrench to tighten spindle bolts to 45-55 ft-lbs. Mark blade orientation for reinstall.
• Mulching vs. bagging: These are mulching blades (curved, with extra lift fins). Not ideal for bagging or side-discharge—swapping may reduce performance.
• Gotcha: The 6-point star hole can wear over time—inspect spindle for rounding before buying. If worn, blades may wobble.

Should You Buy It

If you own a compatible 30-inch rear-engine rider and mow frequently for a clean, mulched lawn, this 2-pack is a budget-friendly replacement. But if you need OEM durability or bagging performance, spend more on genuine Cub Cadet blades.
