CUB CADET 490-110-F204 50" Xtreme Blade Set S Shape Center Hole Fab 50 ZTS2 ZTS1 ZT2 ZT1 XT1 LT50 490-110-Y204

What It Is

This is a set of three 50-inch fabricated steel blades for Cub Cadet zero-turn and lawn tractors, designed for medium-to-large residential properties with heavy grass or occasional tough cutting conditions. The S-shaped center hole and Xtreme design improve lift and mulching performance.

Fitment & Compatibility

Check before buying:

• Deck size: 50-inch cutting deck only. Measure your deck width to confirm.
• Models: Fits Cub Cadet ZTS2, ZTS1, ZT2, ZT1, XT1, and LT50 series with 50-inch fabricated decks. Not for stamped steel decks or smaller/larger decks.
• OEM number: Replaces OEM 490-110-Y204 (original part). Cross-reference your model’s parts list.
• Measurements: Each blade is approximately 16.5 inches long, 2.5 inches wide, with a 5/8-inch center hole and 0.25-inch thickness. Confirm bolt pattern and hole size match your spindle.
• Note: These are “fab” (fabricated) blades – not stamped. They are thicker and heavier than standard stamped blades. Ensure your spindles and deck can handle the extra weight.

Key Things to Know

• Quality: Fabricated steel is more durable than stamped blades, resisting bending on rocks or roots. However, the 3.5-star rating suggests occasional inconsistency in balance or sharpness out of the box.
• Installation: Moderate difficulty. You’ll need a torque wrench (tighten to 70-90 ft-lbs) and a blade removal tool. Always lift the deck and disconnect the spark plug before starting.
• Common gotchas: The S-shaped center hole may not fit all spindles – verify your spindle’s center hole shape (round vs. S-shaped). These blades are heavier, so check your blade engagement system for wear.
• Performance: Better lift and airflow than stamped blades, but may require more engine power. Not ideal for wet or thick grass without slowing down.

Should You Buy It

Buy these if you have a compatible Cub Cadet 50-inch fabricated deck and want a tougher blade that handles debris and thick grass better than standard stamped options. Skip them if your deck is stamped steel or if you prefer lighter blades for easier engine load. For the price, they’re a solid upgrade for residential use, but check balance before installing.
