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

What It Is

This is a set of three replacement mower blades (OEM equivalents 742-05052A and 942-05052A) designed for 50-inch cutting decks on specific Cub Cadet, Troy-Bilt, and MTD lawn tractors and zero-turn mowers. They’re used for cutting grass and mulching leaves on residential or semi-commercial properties.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: Only fits 50-inch decks. Measure your deck width to confirm—this set won’t work on 46-inch, 54-inch, or other sizes.
• Model compatibility: Fits Cub Cadet S50, XT1, GT50, LT50, XT2, and Troy-Bilt/MTD equivalents with a 50-inch deck. Verify your model number on the mower’s ID tag (usually under the seat or on the frame).
• OEM vs aftermarket: These are aftermarket blades, not genuine Cub Cadet parts. They match OEM part numbers 742-05052A and 942-05052A, but tolerances and steel thickness may vary slightly. Check the center hole diameter (usually 7/8-inch) and blade length (typically 20.5 inches) against your old blades.

Key Things to Know

• Quality: Customer rating is 5.0/5 (only 1 review), so long-term durability is unproven. Expect them to be adequate for residential use but possibly thinner or softer than OEM blades.
• Installation difficulty: Easy—requires a socket wrench and a block of wood to lock the blade. No special tools needed. Torque bolts to 70-90 ft-lbs.
• Common gotchas: These blades are non-OEM, so the balance may be off. Always check balance after installation (hang on a nail or use a balancer). Also, verify the blade orientation (sharp edge facing rotation direction) before tightening.
• Mulching vs bagging: These are standard lift blades—fine for mulching with a kit or side discharge, but not optimized for high-lift bagging. If you bag often, consider a dedicated bagging blade.

Should You Buy It

Buy these if you have a confirmed 50-inch deck on a compatible Cub Cadet, Troy-Bilt, or MTD model and need a budget-friendly, quick replacement set for light residential mowing. They’re a solid value if you’re comfortable checking blade balance and don’t require OEM precision. Skip them if you mow heavy, wet grass regularly or need guaranteed durability for commercial use—stick with genuine Cub Cadet blades instead.
