17.05-Inch Mower Blade Replacement for Cub Cadet MTD Troy-Bilt 742P05084 742P05094-L 490-110-C200 Fits 50-Inch Deck Ultima ZT1-50 ZT2-50 Enduro XT1-LT50 XT2-LX50 Diamond Hole 3 PCS

What It Is

This is a 17.05-inch replacement blade set (3-pack) for 50-inch cutting decks on Cub Cadet, MTD, and Troy-Bilt zero-turn and lawn tractors. Designed for heavy-duty mulching or bagging, it fits models like the Ultima ZT1-50, ZT2-50, Enduro XT1-LT50, and XT2-LX50.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be exactly 50 inches (measured blade tip to tip). This blade is 17.05 inches long, so you need three per deck.
• Mounting hole: Uses a diamond-shaped center hole (common on MTD/Cub Cadet decks). Measure your old blade’s hole shape—round or star won’t fit.
• OEM cross-references: This replaces Cub Cadet 742P05084, 742P05094-L, and MTD 490-110-C200. Check your model number (e.g., 13AQA1CQ099) not just series name—some XT1-LT50 variants use different blades.

Key Things to Know

• Quality concern: With a 2.0 rating (1 review), expect possible balance issues or thin steel. Inspect for warping before install.
• Installation difficulty: Easy if you have a torque wrench (tighten to 70-90 ft-lbs) and lift the deck safely. Use anti-seize on bolts to prevent seizing.
• Common gotcha: Diamond hole blades must be oriented correctly—the cutting edge should face the direction of rotation (usually counterclockwise when viewed from above). A wrong orientation dulls quickly and can damage the deck.
• Price vs. OEM: At $45.99 for three, this is cheaper than OEM sets ($60+). But if the quality is poor, you may replace sooner.

Should You Buy It

Buy it only if you’re on a tight budget and can tolerate potential quality issues—like balancing the blades yourself or replacing them sooner. For a reliable cut and longer life, stick with OEM Cub Cadet blades (e.g., 742P05084) or a higher-rated aftermarket brand like Oregon. This set is a gamble best avoided for frequent or commercial use.
