HQPASFY 742-05510 High Lift Lawn Mower Blades, Compatible with 46" Deck Cub Cadet, MTD, Crafts Man, Troy Bilt for Riding & Zero-Turn Mower Blades, Replace OEM 742P05510 CMXGZAM110192, 2 Pack

What It Is

The HQPASFY 742-05510 is a set of two high-lift lawn mower blades designed for 46-inch cutting decks on riding and zero-turn mowers from Cub Cadet, MTD, Craftsman, and Troy-Bilt. The high-lift design increases airflow under the deck, improving grass clipping discharge and bagging performance, especially in thick or tall grass.

Fitment & Compatibility

Before buying, verify three things:

1. Deck size: These blades fit only 46-inch decks. Measure your deck width to confirm.
2. OEM replacement: They replace OEM part numbers 742-05510, 742P05510, and CMXGZAM110192. Cross-reference your mower’s manual or current blade part number.
3. Brand compatibility: Designed for Cub Cadet, MTD, Craftsman, and Troy-Bilt models with a 46-inch deck. Also fits some Yard Machines and Huskee models using the same spindle pattern. Check that your deck uses three blades (each ~15.5 inches long) with a 1-inch center hole and 5-point star drive.

Avoid buying if you have a 42-inch, 50-inch, or 54-inch deck—these blades won’t fit.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and blade removal tool. No special skills needed, but always disconnect the spark plug and battery before working.
• High-lift trade-off: Excellent for bagging and side discharge, but can create more dust in dry conditions and may reduce lift in very wet grass.
• Quality: Made from heat-treated steel with a powder coating for rust resistance. Users report they stay sharp longer than some OEM blades, but inspect for balance out of the box—unbalanced blades cause vibration.
• Common gotcha: The star drive center hole must align with your spindle. If your deck uses a different drive pattern (e.g., oval or hex), these won’t work.

Should You Buy It

If you own a 46-inch deck Cub Cadet, MTD, Craftsman, or Troy-Bilt rider or zero-turn and prioritize bagging or side discharge performance, this is a solid, cost-effective upgrade over standard blades. It’s not for low-lift mulching or decks smaller/larger than 46 inches.
