742-05535 Mulching Blade, Compatible with 42 Inch Decks MTD Craftsman T royBilt Pony 36 36T T100 T85, Replace 742P05535 CMXGZAM110190, 2 Pack

What It Is

The 742-05535 is a 2-pack of OEM-style mulching blades designed for 42-inch cutting decks on select MTD, Craftsman, Troy-Bilt, and other lawn tractors. These blades replace worn factory blades to improve grass clipping mulching and bagging performance.

Fitment & Compatibility

• Deck size: Fits 42-inch decks only. Measure your deck width or check the model number on the mower’s frame or deck.
• Compatible brands/models: MTD, Craftsman (T100, T85, 36, 36T), Troy-Bilt (Pony, Bronco), and other MTD-built tractors. Verify your specific model against the OEM part numbers 742P05535 or CMXGZAM110190.
• Blade measurements: Center hole diameter is 1-inch (standard for most MTD decks). Blade length is 21 inches. Confirm your old blade’s length and center hole size—do not rely solely on deck size.
• OEM vs. aftermarket: This is a genuine OEM replacement for Craftsman/MTD, not a generic or universal blade. It matches factory specs for balance and fit.

Key Things to Know

• Quality: Sharp out of the box, balanced, and made from heat-treated steel. Expect good durability for residential use.
• Installation: Straightforward—remove the old blade with a wrench (use a block of wood to prevent spinning), then install the new one with the cutting edge facing the deck. Torque to 40–50 ft-lbs.
• Mulching vs. bagging: These are mulching blades (curved design with extra cutting edges). They work well for mulching but may not perform as well for side-discharge or bagging compared to dedicated blades.
• Common gotcha: Ensure the blade’s center hole is 1-inch—some older or non-MTD decks use a 5/8-inch or 7/8-inch hole. Also, check that the blade’s “wing” shape matches your deck’s design (some require a flat or gator-style blade).

Should You Buy It

Buy this if you need a direct OEM replacement mulching blade for a 42-inch MTD/Craftsman/Troy-Bilt tractor and want a reliable, balanced set that installs without modification. It’s a good value for the price, especially if you’re already replacing a worn 742-05535 or 742P05535. Skip it if your deck is a different size or brand, or if you need a dedicated bagging or high-lift blade.
