What It Is

This 3-pack set includes two long blades and one short blade designed for 46-inch cutting decks on select Cub Cadet, Troy-Bilt, MTD, and Toro lawn tractors. It replaces OEM part numbers 942-04125, 942-04124, 742-04125, and 742-04124.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck and uses a 3-blade spindle configuration (two outer blades longer, center blade shorter). Check your current blade part numbers—this set directly replaces 942-04125/742-04125 (long) and 942-04124/742-04124 (short). It fits models like Cub Cadet LT1045, LT1046, Troy-Bilt LX2146, and Toro LX460, but verify your specific model number on the mower’s data tag—not just the brand. Measure blade length: long blades are approximately 18.5 inches, short blade approximately 16 inches. Also confirm center hole diameter (typically 1-inch) and spindle shape (oval or star) to match your deck.

Key Things to Know

• Quality & sharpness: These are aftermarket blades, not OEM. Reviewers note they are decently sharp out of the box but may dull faster than genuine Cub Cadet or Stens blades, especially in sandy or rocky soil.
• Installation difficulty: Easy—requires a socket wrench and torque wrench (target 70-90 ft-lbs). Use a blade removal tool or block the blade to prevent spinning. Always disconnect the spark plug first.
• Common gotchas: The short center blade is often overlooked—do not install a long blade in the center position, as it will hit the deck. Also, check blade orientation: the cutting edge should face the direction of rotation (usually upward when installed).
• Balancing: Aftermarket blades may need balancing before installation. Use a simple blade balancer to avoid vibration and spindle wear.

Should You Buy It

Buy this set if you need a budget-friendly, direct-fit replacement for a 46-inch deck on a Cub Cadet, Troy-Bilt, or MTD tractor and are comfortable with basic installation. It’s ideal for homeowners with average-sized lawns who want to save money over OEM blades. Skip it if you mow heavy grass daily or demand premium steel and longevity—consider OEM or a higher-end aftermarket brand like Oregon or Stens instead.
