HQPASFY 742-05535 Lawn Mower Blades Set, Diamond Center Hole Compatible with 36 Inch Deck MTD, Craftsman, TroyBilt, Yard Machines, Replace OEM 742P05535, CMXGZAM110190, 490-110-M190, 2 Pack

What It Is

This is a two-pack of 20-inch lawn mower blades designed for 36-inch cutting decks. They feature a diamond-shaped center hole and are intended for MTD, Craftsman, Troy-Bilt, and Yard Machines tractors.

Fitment & Compatibility

Before buying, measure your deck to confirm it’s a 36-inch model. Check that your spindle hole is diamond-shaped, not round. These replace OEM part numbers 742P05535, CMXGZAM110190, and 490-110-M190. Verify your mower’s model number against the seller’s list—common compatible series include MTD 700, 800, and 900 series, Craftsman 917, and Troy-Bilt 13A series. Blade length is 20 inches, width is 2.5 inches, and the center hole is 5/8-inch diamond. Measure your old blade’s length and hole shape to avoid fit issues.

Key Things to Know

• Quality: Made from heat-treated steel for durability, but some users report they are slightly thinner than OEM blades. Expect a reasonable lifespan for residential use.
• Installation: Straightforward—lift the deck safely, remove the old blade bolt (left-hand thread on most MTD decks), and torque the new blade bolt to 70-90 ft-lbs. Use a blade lock or block of wood to prevent spinning.
• Gotcha: The diamond hole must align with your spindle’s diamond shape. If your spindle has a round hole, these will not fit.
• Balance: Check blade balance before installing. An unbalanced blade causes vibration and poor cut quality.

Should You Buy It

If you need a budget-friendly two-pack for a 36-inch MTD-family tractor and your spindle uses a diamond hole, this is a solid choice for residential mowing. For heavy commercial use, look for a thicker OEM blade.
