742P05094 Mulching Blade Set Fit for Enduro XT1-LT50 Ultima ZT1-50 ZT2-50 50 Inch Deck Heavy Duty Blade Replaces 490-110-C193 490-110-Y193

What It Is

This is a set of three heavy-duty mulching blades designed for 50-inch cutting decks on select Cub Cadet and similar lawn tractors/zero-turn mowers. They chop clippings finely for nutrient recycling, ideal for frequent mowing on medium-to-large lawns.

Fitment & Compatibility

• Deck size: Must be exactly 50 inches. Measure your deck width (blade tip to tip) to confirm.
• Models: Compatible with Cub Cadet Enduro XT1-LT50, Ultima ZT1-50, and ZT2-50. Also fits some other brands with a 50-inch deck using the same spindle pattern.
• OEM cross-references: Replaces Cub Cadet OEM part numbers 490-110-C193 and 490-110-Y193.
• Measurements: Each blade is roughly 20.5 inches long, 2.5 inches wide, with a 5-point star center hole (1-inch diameter) and 0.25-inch thickness. Verify your spindle pattern matches a star-shaped center hole—round or oval holes won’t work.
• What to check before buying: Confirm your mower’s deck size (look for a stamped model number), spindle hole shape, and current blade length. If your OEM blades have a different hole pattern, these won’t fit.

Key Things to Know

• Quality: Heavy-duty steel with a powder coating for rust resistance. Reviews note good balance and sharpness out of the box.
• Installation: Easy DIY job—requires a socket wrench and blade removal tool. Always disconnect the spark plug and wear gloves. Torque bolts to 70-90 ft-lbs.
• Gotcha: These are mulching blades, not lift blades. They produce finer clippings but won’t bag or side-discharge as effectively. For best results, mow frequently and keep grass dry.
• Common issue: Some users report the center hole is slightly tight on certain spindles—file lightly if needed. Avoid over-tightening.

Should You Buy It

If you own a Cub Cadet with a 50-inch deck (XT1-LT50, ZT1-50, or ZT2-50) and want a reliable, affordable mulching upgrade over OEM, this set is a solid choice. It’s best for homeowners who mow regularly and prefer a clean, clippings-free lawn without bagging. Skip it if you need high-lift blades for bagging or tall, wet grass.
