942-04385 742-04385 30 Inch Mulching Mower Blade Compatible with Troy-Bilt TB30 TB30R, Cub Cadet CC30 CC30H, Craftsman R1000 RER1000 R1500 Rear Engine Riding Mowers, 6 Point Star Center Hole, 1 Pack

What It Is

This is a 30-inch mulching blade designed for rear-engine riding mowers with a 6-point star center hole. It replaces OEM part numbers 942-04385 and 742-04385, and is intended for use on Troy-Bilt TB30/TB30R, Cub Cadet CC30/CC30H, and Craftsman R1000/RER1000/R1500 models.

Fitment & Compatibility

Before buying, verify these specifics:

• Deck size: Must be exactly 30 inches. This blade will not fit 32-inch or 42-inch decks.
• Center hole: 6-point star (not a standard 5-point or round hole). Measure your existing blade’s center hole shape.
• Blade length: 30 inches from tip to tip.
• OEM cross-reference: Matches 942-04385 and 742-04385. If your mower uses a different OEM number, this blade likely won’t fit.
• Model check: Works on Troy-Bilt TB30/TB30R, Cub Cadet CC30/CC30H, and Craftsman R1000/RER1000/R1500. Not compatible with other rear-engine or zero-turn models.

Key Things to Know

• Quality: Aftermarket blade, not OEM. Made from hardened steel, but may be slightly thinner or lighter than original. Check for burrs on edges before installing.
• Installation: Straightforward swap—remove bolt, replace blade, torque to 35-45 ft-lbs. Use a thread locker if recommended by your mower’s manual.
• Mulching vs. bagging: Designed for mulching (fine clippings). Not ideal for side-discharge or bagging—will leave larger clumps if used with those setups.
• Common gotcha: The 6-point star hole is less common than 5-point. Verify your mower uses this pattern—many Craftsman and Cub Cadet rear-engine models do, but not all.

Should You Buy It

If you have a 30-inch rear-engine Troy-Bilt, Cub Cadet, or Craftsman mower with a 6-point star center hole and want a budget-friendly mulching blade, this is a solid option. It’s not OEM, but for the price and with a 4.6-star rating, it’s a good replacement for worn-out originals. Skip it if you need a bagging or side-discharge blade, or if your mower uses a different center hole pattern.
