RYOBI OEM 680856014 Blade 20T Steel

What It Is

The RYOBI OEM 680856014 is a 20-inch, 3-in-1 steel blade designed to mulch, bag, or side-discharge grass clippings. It’s made for select RYOBI 20-inch push mowers, typically found on electric or gas models requiring a single, straight replacement blade.

Fitment & Compatibility

Before buying, measure your existing blade length—this one is exactly 20 inches from tip to tip. Check your mower’s model number (e.g., RY48110, RY401140, RY401150, RY40190, or RY40190US) in the owner’s manual or under the deck. This is an OEM (original equipment manufacturer) part, so it will match the mounting hole pattern and offset exactly—no need to modify. If you have a different brand (Toro, Honda, etc.), this blade will not fit without adapter kits, which are not included.

Key Things to Know

• Steel quality: Medium-carbon steel—sharp enough for normal residential lawns but dulls faster than high-lift or hardened blades. Expect to replace every 1-2 seasons with regular use.
• Installation difficulty: Easy—requires a 5/8-inch socket or wrench to remove the center bolt. Always disconnect the spark plug or battery before flipping the mower.
• Balancing: It comes pre-balanced, but check with a blade balancer after sharpening. An unbalanced blade causes vibration and can damage the spindle.
• 3-in-1 design: The blade has a flat profile—works fine for mulching, but if you need heavy mulching performance, consider a dedicated mulching blade (different part number).

Should You Buy It

If you own a compatible RYOBI 20-inch mower and want a direct, hassle-free replacement that restores stock cutting performance, this blade is a solid choice. It’s affordable, easy to install, and reliable for standard residential lawns—just don’t expect it to outperform premium aftermarket blades on thick, wet grass.
