942-05056a High Lift Blades Fit for 54" Deck Cub Cadet RZT-L54 RZT-S54 ZT1 54 Troy Bilt Mustang XP 54 Craftsman 54" Zero Turn Mower, Replaces 742-05256A 942-05256 742-05256, 3 Pack 

What It Is

This is a 3-pack of high-lift blades for 54-inch zero-turn mower decks, designed to improve grass clipping discharge and bagging performance compared to standard blades. Best for residential use on Cub Cadet, Troy-Bilt, and Craftsman ZTRs.

Fitment & Compatibility

Before buying, confirm your deck is exactly 54 inches (measure cutting width, not the deck shell). These fit Cub Cadet RZT-L54, RZT-S54, ZT1 54; Troy-Bilt Mustang XP 54; and Craftsman 54" zero-turn models. They replace OEM part numbers 742-05256A, 942-05256, and 742-05256. Measure your existing blade length (should be ~20.5 inches) and center hole size (typically 1 inch). Check spindle bolt pattern – these use a 5-point star center hole. Aftermarket, not OEM, so minor thickness or balance differences are possible.

Key Things to Know

• Installation: Straightforward – remove spark plug wire, block blade, use a socket wrench. Torque spindle bolts to 70-90 ft-lbs.
• Quality: 4.4-star rating from 69 reviews; most users report good balance and sharpness out of the box. Some note they’re slightly thinner than OEM.
• Performance: High-lift design creates more suction for bagging but uses more engine power – avoid on wet grass. Expect more wear than standard blades.
• Gotchas: Verify your deck’s blade orientation (some require specific indexing). Check for bent spindles before installing – common on used ZTRs.

Should You Buy It

Buy these if you need a budget-friendly 3-pack for a compatible 54" zero-turn and prioritize bagging or clean-cut in dry grass. Skip them if you want OEM-grade thickness or mow in wet conditions – low-lift or mulching blades would serve you better.
