What It Is

The Cub Cadet 490-110-F203 is a set of three 46-inch Xtreme blades designed for heavy-duty mowing on zero-turn and lawn tractors. These S-shaped, fabricated blades are built for mulching, bagging, or side-discharge use on Cub Cadet ZTS1, ZT1, XT2, XT1, LX46, and LT46 series mowers.

Fitment & Compatibility

• Deck size: Only fits 46-inch cutting decks. Measure your deck width before ordering.
• Model compatibility: Fits Cub Cadet ZTS1, ZT1, XT2, XT1, LX46, and LT46 models. Also replaces OEM part numbers 742P05510-X and 742-05510-X.
• Blade dimensions: 16.5 inches long, 2.5 inches wide, 0.203 inches thick, with a 1-inch center hole and 0.75-inch offset. Measure your existing blades to confirm.
• OEM vs aftermarket: This is a genuine Cub Cadet OEM blade set, not a generic replacement. Guaranteed fit for listed models.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and blade removal tool. No special skills needed.
• S-shape design: The fabricated S-shape improves lift and airflow for better mulching and bagging, but can be more prone to bending if you hit rocks or stumps.
• Durability: Heat-treated steel holds an edge longer than stamped blades, but they’re heavier and may require a balanced set for vibration-free operation.
• Common gotcha: Always check blade orientation—the S-curve must face upward toward the deck for proper cutting action. Also, tighten bolts to 70-90 ft-lbs; over-torquing can strip the spindle.

Should You Buy It

Buy this set if you own a compatible Cub Cadet 46-inch deck and want OEM-quality blades for frequent, heavy-duty mowing. It’s ideal for mulching and bagging performance, but skip it if you mow rocky or debris-filled lawns—the fabricated S-shape is more vulnerable to damage than standard stamped blades.
