742-05535 Mulching Mower Blades for MTD Craftsman Troy Bilt T100 T85 Pony 36T 42-Inch 490-110-M190 742P05535 CMXGZAM110190 2 Pack

What It Is

This is a 2-pack of mulching blades designed to replace OEM parts on MTD-built lawn tractors, including Craftsman, Troy-Bilt, and Yard Machines models. They fit 36-inch and 42-inch cutting decks and are intended for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

Before buying, verify your deck size (36” or 42”) and check your mower’s model number—common compatible models include Craftsman T100, T85, and Troy-Bilt Pony. These blades replace OEM part numbers 742-05535, 490-110-M190, 742P05535, and CMXGZAM110190. Measure your existing blade’s length (typically 18.5” for 42” decks), center hole diameter (usually 1”), and thickness (approx. 0.25”). Also confirm the blade’s offset or lift angle matches your deck design—mulching blades often have a more curved profile than standard blades.

Key Things to Know

• Quality concerns: With a 3.5-star rating from only 3 reviews, some users report blades being slightly thinner or less durable than OEM versions. Check for burrs or uneven edges before installation.
• Installation difficulty: Easy to moderate—requires a socket wrench and possibly a blade removal tool. Always disconnect the spark plug and tip the mower (fuel side up) for safe access.
• Common gotchas: These blades may not fit decks with a spindle bolt size smaller than 5/8” (common on older MTD models). Also, mulching blades need a properly designed mulching baffle or plug—if your deck is set up for bagging or side discharge, performance will suffer.
• Balance: After installing, check blade balance with a simple balancer to avoid vibration and uneven cuts.

Should You Buy It

Buy these if you need a budget-friendly replacement for a 36” or 42” MTD/Craftsman/Troy-Bilt mower and primarily mulch grass in clean, dry conditions. They’re a decent value for the price, but if you have a heavy-duty or commercial use, or want guaranteed OEM fit and durability, consider spending more on genuine MTD or Oregon blades.
