Youxmoto AM31100 46" Toothed Mower Blade for John Deere F510 F525 LT166 STX46 116 180 185 210 212 214 216 240 245 260 265 285 300 316, for John Deere AM31100 M41967 Lesco 050335, 3 Pack

What It Is

This is a 3-pack of 46-inch toothed mower blades designed for high-lift cutting on medium-duty John Deere and Lesco lawn tractors. Ideal for mulching or bagging grass in residential or commercial mowing.

Fitment & Compatibility

Before buying, check your deck size—these blades are 46 inches total length, so they only fit 46-inch cutting decks. They replace OEM John Deere part AM31100 and M41967, and Lesco 050335. Compatible models include John Deere F510, F525, LT166, STX46, and 100–300 series tractors (116, 180, 185, 210, 212, 214, 216, 240, 245, 260, 265, 285, 300, 316). Measure your current blade’s length, center hole diameter, and offset to confirm fit—these use a 1-inch center hole and 5/8-inch spindle hole. Not for standard 42-inch or 54-inch decks.

Key Things to Know

• Quality: Aftermarket blades, not OEM. Expect adequate durability for residential use, but may dull faster than factory blades on heavy or sandy grass.
• Installation: Easy bolt-on replacement with basic tools (socket wrench). Ensure blades are torqued to spec (typically 70–90 ft-lbs) and oriented with lift wings facing upward.
• Common gotcha: These are toothed (serrated) blades—they cut finer clippings but can produce more noise and vibration than straight-edge blades. Check for balance before installing.
• Pack size: 3-pack is cost-effective for multiple mowers or spares, but verify all three match your deck’s blade pattern (some decks use two long blades and one shorter one).

Should You Buy It

If you own a compatible John Deere or Lesco with a 46-inch deck and want a budget-friendly 3-pack for mulching or bagging, this is a solid buy. It’s not for high-end commercial use or decks over 46 inches, but it’s a good value for the price.
