Grasscool 742p05510 S Shaped Hole Blades for Cub Cadet 46 inch Mower Enduro XT1 LT46 XT1-46 Zero Turn Lawn Tractor Replace 742P05510-X 490-110-C203

What It Is

This is a set of three S-shaped hole blades designed for 46-inch cutting decks on Cub Cadet Enduro XT1 LT46, XT1-46, and zero-turn models. The S-shaped hole pattern fits specific spindle mounts; it’s a direct replacement for OEM part numbers 742P05510-X and 490-110-C203.

Fitment & Compatibility

Before buying, confirm your deck is exactly 46 inches (measure from blade tip to blade tip across the deck). These blades fit Cub Cadet Enduro XT1 LT46, XT1-46, and XT1-46 zero-turn mowers. They also work on some MTD and Troy-Bilt models with the same spindle mount pattern. Measure your current blades: length should be 15.5 inches, width about 2.25 inches, and the center hole must be S-shaped (not round or star). If your spindle uses a different hole shape (e.g., oval or D-shape), these won’t mount. Aftermarket, not OEM.

Key Things to Know

• Quality concerns: 3.6/5 rating with 17 reviews suggests mixed feedback—some report balance issues or premature dulling. Inspect for warping before installing.
• Installation difficulty: Easy if you have a blade removal tool and torque wrench. Tighten to 70-80 ft-lbs. S-shaped hole aligns with spindle pins; no adapter needed.
• Common gotcha: The S-shaped hole is specific—double-check your spindle’s pin pattern. If your deck uses a different hole style (e.g., offset oval), these won’t fit.
• Sharpness: They come pre-sharpened but may need a touch-up after first use for optimal cut quality.

Should You Buy It

Buy these if you need a budget-friendly replacement for a Cub Cadet 46-inch deck with S-shaped spindle mounts and you’re comfortable with aftermarket quality variance. Skip if you want OEM-grade durability or have a different hole pattern—spend more on factory blades for consistent balance and edge life.
