742P05510-X 490-110-C203 23.25" Mulching Blades (3 Pack) Compatible with Cub Cadett MTD XT2-LX46 XT1-LT46 ZTS1 ZT1 46 Replacement for 46" Cutting Deck Lawn Mowers, Replaces 742-05510-X CMXGZAM110203

What It Is

This is a 3-pack of 23.25-inch mulching blades designed for 46-inch cutting decks on Cub Cadet and MTD lawn tractors and zero-turn mowers. They’re intended for mulching grass clippings into fine particles that decompose quickly, reducing bagging needs.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch cutting deck—this pack fits decks that use three blades (each 23.25″ long). Compatible models include Cub Cadet XT2-LX46, XT1-LT46, ZTS1, and ZT1 46, plus other MTD-built tractors with that deck size. These replace OEM part numbers 742-05510-X and CMXGZAM110203. Measure your existing blade length (center hole to tip) to be sure—aftermarket blades can vary slightly. Also check the center hole diameter (usually 7/8″ or 1″) and the offset/dish shape to match your deck. Not for 42″ or 54″ decks.

Key Things to Know

• Quality vs OEM: These are aftermarket blades, often made from lighter-gauge steel than genuine Cub Cadet parts. They may wear faster or dull sooner, especially in rocky or sandy soil.
• Installation difficulty: Moderate. You’ll need a socket wrench and a blade removal tool (or a block of wood to stop the blade). Always disconnect the spark plug before working under the deck.
• Balance check: Aftermarket blades can be out of balance out of the box. Test balance on a blade balancer or nail—vibration can damage your spindle bearings over time.
• Mulching performance: These blades have a higher lift and more curved surface than standard blades, which helps chop clippings finer. But they won’t perform well in wet, tall grass—mulch in dry conditions only.

Should You Buy It

Buy this pack if you own a 46″ Cub Cadet or MTD tractor, want to mulch instead of bag, and are comfortable with occasional replacement (maybe every season or two). It’s a budget-friendly alternative to OEM blades, but expect slightly shorter lifespan and check balance before installation. Not ideal for heavy commercial use or if you need maximum durability.
