Persistence pays off!
I have been looking for a new mower blade for my Kolbalt electric mower. Lowes was useless they said the blade isn’t made anymore,another co. bought out their supplier. I ordered several blades on Amazon that I thought would fit but they didn’t. I saw this brand greenworks on Amazon the locating holes looked the same, length was the same so I ordered it. got it ,fit fine locating holes, matched! I can’t believe it! Finally after searching for months!

Same as more expensive out there
Perfect fit, easy install for someone that knows what they’re doing, took 5 minutes for son-in-law. Cutting well, munched pile of leaves straight away.

Solved my mower batteries running out fast
I couldn’t figure out why my lawn mower batteries were dying really fast. Then it dawned on me that the blades have never been shaped or replaced. Ordered the pair for the Greenworks Lawn Mower (20″ Mowers : 25302) and them installed and the battery life is back!I did have a hard time removing the older blades and tightening the new ones. Greenworks has videos on how to use a 2×4 to make it easier.

Will not fit a Ryobi 40v self propelled mower
Got a defective one. There is a half moon key on one side, the large plastic circle hub in the middle, and a small circle key on the other. None of this stuff lines up, and the middle hub and half moon keys were too small. Also, the blade is overall about a quarter inch too small. Sending it back. This will NOT fit a Ryobi 40v self propelled mower, so don’t waste your time.
