3PCS 742-05052A 942-05052A Blades for 50 Inch Deck Lawn Mower 2-in-1 Blades Compatible with Cub Cadet Troy Bilt MTD Lawn Tractors and RZT Mower S50 XT1 GT50 LT50 XT2 with 50'' Deck

What It Is

This is a set of three 2-in-1 (mulching and bagging) replacement blades designed for 50-inch deck lawn tractors and zero-turn mowers. They fit Cub Cadet, Troy-Bilt, and MTD models, including the S50, XT1, GT50, LT50, and XT2 series.

Fitment & Compatibility

• Deck Size: Only for 50-inch decks—measure your deck width to confirm.
• OEM Cross-Reference: Replaces OEM part numbers 742-05052A and 942-05052A. Also compatible with 742-05052, 942-05052, and 742-05052B.
• Model Check: Fits Cub Cadet S50, XT1 (enduro series), GT50, LT50, and XT2 with 50" decks. Also fits Troy-Bilt and MTD tractors with the same deck size—verify your model number against the OEM list.
• Measurements: Blade length is 18.5 inches, center hole diameter is 1 inch (oval center hole). Check your blade’s length and hole shape before purchase.
• Aftermarket Note: These are not OEM Cub Cadet blades but are marketed as direct replacements. Confirm your spindle orientation and blade offset (flat vs. curved) match your current blades.

Key Things to Know

• Quality: Made from heat-treated steel, reasonably durable for residential use. Some users report they dull faster than OEM blades on rocky or heavy grass.
• Installation: Straightforward—remove the old blade, clean the spindle, and torque the bolt to 70-80 ft-lbs. Use a blade removal tool for safety.
• Gotcha: These are 2-in-1 (mulch/bag) blades, not high-lift for side discharge. If you need maximum bagging performance, consider high-lift blades instead.
• Balance: They come pre-balanced, but always check with a blade balancer before installing to avoid vibration.

Should You Buy It

Buy these if you have a Cub Cadet, Troy-Bilt, or MTD 50-inch deck tractor or ZTR, need a budget-friendly 3-pack replacement for mulching or bagging, and are comfortable with aftermarket quality. Skip them if you want OEM durability or need high-lift blades for heavy side discharge.
