8TEN LawnRAZOR Mower Blade Set for MTD Cub Cadet RZT S54 L54 Troy Bilt 54 inch Deck 942-05056A 942-05056 (High Lift)

What It Is

This is a set of three high-lift replacement blades designed for 54-inch cutting decks on select MTD, Cub Cadet, and Troy-Bilt zero-turn mowers. The aggressive lift profile improves grass clipping discharge and bagging performance compared to standard blades.

Fitment & Compatibility

• Deck size: Fits 54-inch decks only. Measure your deck width to confirm.
• OEM cross-reference: Replaces Cub Cadet / MTD part numbers 942-05056A and 942-05056.
• Common models: Cub Cadet RZT S54, L54, and Troy-Bilt models with 54-inch fabricated decks. Check your owner’s manual or existing blade part number before ordering.
• Center hole: 7/8-inch round. Measure your spindle’s center hole diameter to verify.
• Blade length: 18 inches. Confirm your current blades are this length.
• Aftermarket note: These are not OEM Cub Cadet blades. They are a compatible aftermarket option from 8TEN.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench and a blade removal tool or block of wood to prevent spinning. Always disconnect the spark plug first.
• High-lift trade-off: Better discharge and bagging, but they require more engine power and may leave uneven stripes in wet or tall grass. Not ideal for mulching.
• Balance check: Some users report needing to balance blades before first use. Use a blade balancer to avoid vibration and spindle wear.
• Durability: Heat-treated steel holds an edge well for residential use. Not recommended for commercial mowing or rocky terrain.

Should You Buy It

If you own a Cub Cadet or Troy-Bilt zero-turn with a 54-inch deck and want better clipping lift for bagging or side discharge, this set offers solid value at a lower price than OEM blades. It’s a good fit for homeowners who mow regularly and don’t need mulching performance. Avoid if you prefer OEM parts or have a commercial mowing operation.
