I can’t remember for sure but I bought my 60 volt Greenworks mower about 4 or 5 years ago. I have been putting off replacing the blade because I just knew it would be beyond my abilities. I even considered having it done.

Besides all this, I didn’t have a wrench the right size. (see Wrenches, Wrenches and Wrenches in which I explained that, regardless of my dozens of wrenches, I never have the right size.) I spent a few hours checking the internet in hopes of getting some help.

First, much of the info was contradictory. Second, it was not specific to my mower. Finally, it seemed to suggest a confirmation that it would be too much for an old man.

As for the wrench thing, I resolved that problem by buying a large Cresent adjustable wrench for $8. I’m sure it would be better to use the right size wrench, but the adjustable wrench worked well.

The procedure took right about 15 minutes. If I did it again today, it would take 4, maybe 5 minutes. Indeed, I was surprised how easy it was.

I must truly give Greenworks acalaides for this mower. Other than the blade, it has performed as well as day 1 for me. Even the blade, which has had a lot of abuse was not bad for a 4 year old blade. It still cut, just a little unevenly.

Now that I know how, I will replace the blade every year and I suggest others do the same. If nothing else, it is likely better to cut the grass rather than tear it.

As my aside, I do find it odd that many mower repair shops are too busy to repair mowers, especially in the spring. I guess in a strange way it does make sense. It is why we should get our mowers fixed in the autumn.
