What It Is

The 942-0741A is a mulching mower blade set designed for 21-inch deck push mowers from Cub Cadet, MTD, and Troy-Bilt. These blades chop grass into fine clippings to return nutrients to the lawn, ideal for regular mowing without bagging.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: Only fits 21-inch cutting decks. Measure your deck width to confirm.
• OEM cross-references: Replaces OEM numbers 742-0741, 742-0741A, and 942-0741. Direct replacement for Cub Cadet, MTD, and Troy-Bilt models.
• Model compatibility: Fits Troy-Bilt TB130, TB240, TB160, TB115, TB230, TB110, and Craftsman M230, M250. Also works with many MTD and Cub Cadet 21-inch push mowers from the 2000s onward.
• Measurement check: Blade length should be 21 inches overall, center hole 1 inch diameter, with a 5-point star center pattern. Verify your deck’s blade bolt size (typically 5/16” or 3/8”).

Key Things to Know

• Quality: Aftermarket blades—sharp out of box, but may need balancing. Check them on a blade balancer before installing.
• Installation difficulty: Easy—just a socket wrench. Torque blade bolt to 35-40 ft-lbs. Use thread locker for safety.
• Common gotcha: These are mulching blades only. They won’t bag or side-discharge well. If you switch between modes, keep a set of standard blades handy.
• Durability: Medium-carbon steel, holds edge okay for a season of normal use. Replace if you hit rocks or roots often.

Should You Buy It

If you own a compatible Troy-Bilt, Craftsman, or Cub Cadet 21-inch push mower and want a budget-friendly mulching upgrade that works out of the box, this is a solid pick. Not for bagging or heavy-duty commercial use—perfect for weekly home lawn maintenance.
