8TEN LawnRAZOR Mower Blade Set for Cub Cadet 942-04053C MTD Troy-Bilt RZT 50 LGT LT 1050 942-04053B 942-04056c (High-Lift)

What It Is

This is a set of three high-lift replacement blades designed to increase suction and clipping dispersal for Cub Cadet, MTD, and Troy-Bilt zero-turn and lawn tractors with 50-inch or 54-inch decks. Best for mulching or bagging in thick grass.

Fitment & Compatibility

• Deck size: Fits 50-inch (RZT 50, LGT 1050) and 54-inch decks. Measure your blade length—these are 18.5 inches long, 2.5 inches wide, with a 1-inch center hole and 7-point star drive.
• OEM cross-reference: Replaces Cub Cadet 942-04053C, 942-04053B, 942-04056C, and MTD 742-04053C. Not compatible with 42-inch or 46-inch decks.
• Check your model: Confirmed for Cub Cadet RZT 50, RZT 54, LGT 1050, LT 1050, and Troy-Bilt 50-inch zero-turns. Verify your deck part number or existing blade part number before buying.
• Aftermarket note: These are not OEM but are direct-fit replacements. No adapter or modification needed if your deck matches.

Key Things to Know

• High-lift design improves grass lift and bagging but creates more vibration on uneven blades. Inspect each blade for balance before install.
• Installation difficulty: Easy for DIYers. Requires a socket wrench and torque to 70-90 ft-lbs. Use thread locker on bolts to prevent loosening.
• Common gotcha: The star drive center hole is specific to MTD-style spindles. Will not fit standard round-hole spindles (e.g., John Deere, Husqvarna).
• Durability: Heat-treated steel holds an edge well, but high-lift blades wear faster in sandy or rocky soil. Replace when bent or nicked.

Should You Buy It

Buy this set if you own a 50-inch or 54-inch Cub Cadet or MTD zero-turn or lawn tractor and want improved bagging or mulching performance at a price well below OEM. Skip it if your deck uses a different blade length, center hole, or spindle design—or if you prefer standard lift blades for dry, sparse grass.
