Is a lawn mower blade patented?

Short answer: specific designs of a lawn mower blade have been patented many times, but "a lawn mower blade" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a lawn mower blade been patented?” but “has my combination of features been described before?” Outdoor products differ mostly in weatherproofing, power source, folding mechanisms and how they mount or anchor.
