High Lift Mower Blades 23.25 Inch Replacement for Cub Cadet 742P05510-X 742-05510-X MTD Craftsman Troy-Bilt 46-Inch Deck Diamond Center Hole with Nuts and Washers 2PCS

What It Is

These are 23.25-inch high-lift mower blades designed to replace OEM Cub Cadet part 742P05510-X (742-05510-X) and fit 46-inch cutting decks on Cub Cadet, MTD, Craftsman, and Troy-Bilt tractors. The high-lift design creates stronger airflow to lift grass for a cleaner cut and better bagging or side-discharge performance.

Fitment & Compatibility

• Deck size: Confirmed for 46-inch decks only. Measure your deck width before ordering—23.25" blades will not fit 42" or 54" decks.
• Brand/models: Fits Cub Cadet, MTD, Craftsman, and Troy-Bilt models that use OEM part 742P05510-X or 742-05510-X. Check your owner’s manual or current blade part number.
• Center hole: Diamond-shaped center hole (not round). Verify your spindle matches—most Cub/MTD spindles do, but some older decks use a round hole.
• Includes: 2 blades, nuts, and washers. No additional hardware needed if your spindles are in good condition.

Key Things to Know

• High lift = more power draw. These blades require a stronger engine to maintain blade speed. Not ideal for underpowered or older mowers—you may notice bogging in tall, wet grass.
• Installation tip: Torque spindle nuts to 40–50 ft-lbs. Overtightening can warp the blade or damage the spindle.
• Sharpness: Blades come unsharpened (common for aftermarket). You’ll need to sharpen them before first use for best cut quality.
• Balance: Always check blade balance after sharpening. An unbalanced blade causes vibration and can damage your spindle bearings.

Should You Buy It

If you have a 46-inch Cub Cadet, MTD, Craftsman, or Troy-Bilt tractor with a diamond-hole spindle and want improved bagging or side-discharge performance, these blades are a solid budget pick. Just be ready to sharpen them and verify your engine has enough power to handle the extra lift.
