What It Is

This is a 3-pack of mulching blades designed for 50-inch cutting decks on Cub Cadet, MTD, and Troy-Bilt lawn tractors. They replace OEM part numbers 942-04053, 742-04053C, and 942-04053-X, and are intended for mulching (fine clippings) rather than bagging or side-discharge.

Fitment & Compatibility

• Deck size must be exactly 50 inches – measure your deck width (blade tip to tip) before buying. These will not fit 46-inch or 54-inch decks.
• Models confirmed: Cub Cadet RZT 50, LTX1050, LT1050, and MTD/Troy-Bilt 50-inch deck tractors. Check your mower’s model number (under seat or frame).
• OEM vs aftermarket: These are aftermarket replacements, not genuine Cub Cadet parts. They match OEM specs but may have slight differences in thickness or balance.
• Measure your old blade: Center hole diameter should be 1 inch, blade length 20.5 inches, and thickness 0.25 inches. If yours differ, these won’t fit.
• Spindle compatibility: Works with standard 3-point mounting – no special adapters needed.

Key Things to Know

• Mulching only: These blades have a higher lift and more curve than standard blades, so they won’t bag or side-discharge well. Use with a mulching plug/cover for best results.
• Installation: Moderate difficulty – you’ll need a socket wrench and torque wrench (recommended 70-90 ft-lbs). Always lift the deck and disconnect the spark plug first.
• Balance check: Aftermarket blades may not be perfectly balanced. Use a blade balancer before mounting. Unbalanced blades cause vibration, poor cut, and spindle wear.
• Sharpness out of box: Many users report they’re duller than OEM blades. Consider sharpening before first use for a clean cut.
• Rating caveat: 3.8 stars with 21 reviews – some report premature dulling or bending in rocky soil. Not for heavy debris or professional use.

Should You Buy It

Buy if you need a budget-friendly 3-pack for mulching on a 50-inch Cub Cadet or MTD deck and you’re comfortable with basic installation and balancing. Skip if you want OEM durability, bagging performance, or a blade that stays sharp more than a season. For light-to-moderate residential mulching, it’s a decent value.
