What It Is

This is a 3-pack of 54-inch high-lift mower blades (model 942-05056A) with three blade nuts (712-0417A) designed for Cub Cadet zero-turn and lawn tractors. The high-lift design increases airflow for better grass discharge and bagging performance, making it ideal for mulching or collecting clippings.

Fitment & Compatibility

Before buying, check your deck size—these fit only 54-inch cutting decks. Compatible models include Cub Cadet Ultima ZT1 54, ZT2 54, RZT L54, S54, SX54, XT1 GT54, and GT54. They replace OEM part numbers 742-05056A and 742P05056A. Each blade uses a 6-point star center hole and measures approximately 18.5 inches long, 2.5 inches wide, with a 0.25-inch thickness. Verify your spindle mount matches the star pattern (not round or oval). The included blade nuts (712-0417A) are specific to Cub Cadet spindles—do not substitute generic hardware.

Key Things to Know

• Quality: These are OEM-equivalent blades with a durable powder coating to resist rust. High-lift design may cause more noise and vibration than standard blades.
• Installation: Easy bolt-on job with basic tools—a socket wrench and torque wrench (recommended 50-60 ft-lbs). Use a blade removal tool or block the blade to prevent spinning.
• Common Gotchas: Ensure the blade’s 6-point star aligns perfectly with the spindle; forcing it can damage the mount. Replace all three blades at once for balanced cutting. High-lift blades consume slightly more engine power.
• Maintenance: Sharpen or replace every 25 hours of use or at the start of each season. Check blade balance after sharpening.

Should You Buy It

If you own a compatible Cub Cadet with a 54-inch deck and need a reliable, affordable set of high-lift blades for superior mulching or bagging, this 3-pack with nuts is a solid choice. It’s not for standard lift or side-discharge-only use—stick to medium-lift blades if you don’t need the extra airflow.
