Mr Mower Parts Mulcher Blade Set 46" Deck Compatible with CUB Cadet 742-05510-X Xtreme 23.25" Blade S-Shaped Enduro XT1 XT2-2 Pack

What It Is

This is a set of two S-shaped mulching blades designed for 46-inch Cub Cadet XT1 and XT2 Enduro series lawn tractors. They replace OEM part 742-05510-X and are built to finely chop grass clippings for nutrient recycling, not for bagging or side-discharge use.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Must be a 46-inch cutting deck (measured blade tip to tip).
• Blade length: Each blade is 23.25 inches long, with a 5-point star center hole and 1-inch diameter.
• Model compatibility: Fits Cub Cadet XT1 (LT46, GT46), XT2 (LX46, GX46), and other Enduro series tractors that use OEM 742-05510-X. Check your owner’s manual or current blade’s part number.

Not compatible with 42-inch or 54-inch decks, or non-Cub Cadet brands without checking spindle dimensions.

Key Things to Know

• Quality: Made from heat-treated boron steel with a baked-on paint finish. Users report sharpness out of the box and good durability, though some note the paint chips quickly—this is cosmetic only.
• Installation difficulty: Easy. Remove deck, lift mower, or block safely. Use a torque wrench to tighten spindle bolts to 70–80 ft-lbs (check your manual).
• Gotcha: These are mulching-specific blades. They will not bag or discharge well. If you switch between mulching and bagging, you’ll need to swap blades.
• Common issue: The S-shape can cause more vibration if not balanced. Always check blade balance after installation.

Should You Buy It

If you own a Cub Cadet XT1 or XT2 with a 46-inch deck and primarily mulch your lawn, this set offers a solid aftermarket alternative at half the price of OEM. It’s not for baggers or side-discharge users, but for mulching performance and value, it’s a reliable choice.
