What It Is

The 942-0741A is a 21-inch replacement mower blade designed for 21’’ deck riding mowers from Troy-Bilt, Craftsman, Cub Cadet, and MTD. It’s intended for standard mulching or side-discharge cutting on residential lawn tractors.

Fitment & Compatibility

Before buying, verify your deck is exactly 21 inches (measure center-to-center of spindle holes, not overall deck width). This blade fits Troy-Bilt TB130, TB240, TB230, TB200, TB210, TB160 models, plus Craftsman M230, M250, and select Cub Cadet and MTD riding mowers. It replaces OEM part numbers 742-0741, 742-0741A, and 942-0741. The blade measures 21’’ long, 2.25’’ wide, with a 1’’ diameter center hole and 7-point star spindle pattern (7/8’’ center hole if non-star). If your spindle uses a 5-point star or a different hole pattern, it won’t fit.

Key Things to Buy

• Quality: This aftermarket blade is made from hardened steel, similar to OEM. Expect decent durability for residential use, but may dull faster than premium brands on heavy or rocky lawns.
• Installation: Easy—requires a socket wrench and safety glasses. Torque blade bolts to 35-45 ft-lbs. Use thread locker if bolts are not self-locking.
• Common gotchas: The star pattern must match your spindle exactly—some MTD spindles use a 5-point star, not the 7-point this blade requires. Also, this is not a universal blade; it will not fit most 21’’ push mowers or zero-turn decks.
• Balance: Check blade balance after installation. Unbalanced blades cause vibration, poor cut, and spindle wear.

Should You Buy It

If you own a compatible 21’’ riding mower from Troy-Bilt, Craftsman, Cub Cadet, or MTD and need an affordable direct replacement for worn OEM blades, this is a solid choice. Skip it if your spindle uses a different hole pattern or if you need a gator/mulching blade—this is a standard lift blade.
