46" Lawn Mower Decks Blades Fit for Cub Cadet MTD XT2 LX46 XT1 LT46 ZTS1 ZT1 46 Craftsman Z5450 Z5400 T2400 Lawn Mower Replace OEM 742-05510-X 742P05510-X 490-110-Y203 2 Pack

What It Is

This is a 2-pack of 46-inch lawn mower blades designed for select Cub Cadet, MTD, and Craftsman zero-turn and lawn tractors. They replace OEM part numbers 742-05510-X, 742P05510-X, and 490-110-Y203, and are intended for use on residential mowers with a 46-inch fabricated or stamped deck.

Fitment & Compatibility

Before buying, confirm your mower deck is 46 inches wide. These blades fit specific models: Cub Cadet XT2 LX46, XT1 LT46, ZTS1, ZT1 46; Craftsman Z5450, Z5400, T2400; and MTD equivalents. Measure your existing blade length—these are typically 20.5 inches long with a 1-inch center hole and a 0.25-inch offset (check your blade for exact specs). They are aftermarket replacements for OEM parts listed above, not OEM. Verify your spindle pattern: these are dual hole or star pattern compatible (most Cub Cadet/MTD 46-inch decks use a 5-point star). If your blade has a different hole pattern or length, these won’t fit.

Key Things to Know

• Quality vs. OEM: These are aftermarket blades, typically made of hardened steel. They may be slightly thinner or have a different edge profile than OEM Cub Cadet blades, but are generally durable for residential use.
• Installation: Easy for DIY—use a socket wrench and blade removal tool. Always lift the mower, disconnect the spark plug, and wear gloves. Torque the blade bolt to 70–90 ft-lbs (check your manual).
• Sharpness: They come sharp but not razor-sharp. If you want a finer cut, you can sharpen them before first use. Expect to replace or sharpen every 25–30 hours of mowing.
• Common gotcha: Some users report these blades don’t fit perfectly on certain Craftsman Z5400 models with a different spindle offset. Measure your existing blade’s center hole to spindle distance before buying.

Should You Buy It

If you own a qualifying Cub Cadet, MTD, or Craftsman 46-inch mower and want a budget-friendly, reliable blade that matches OEM specs, this 2-pack is a solid choice for regular residential mowing. It’s not for commercial use or if you need a premium, multi-surface blade (e.g., for mulching or bagging). For most homeowners, it’s a good value replacement.
