Greenworks 80v From Costco Shrill Sound

[MrOkie]

Hi, I would appreciate any feedback for owners of the 80v Greenworks mower from Costco. First use I immediately noticed a shrill sound from the motor, almost like a one pitch siren. It's not super loud, but quite annoying. Is this normal for this mower? I also have a 60v Greenworks mower (which I love) purchased in 2019, and it does not have that sound. Any thoughts? Thanks!

I have a 60V too, that I am very happy with. I suggest contacting Greenworks ;

Thanks. I'll double check after I get off work.

wonder if, as a test, you could try it without the blade installed?

So, I decided purchase a second mower at Costco to compare. The second mower did not make that high pitch sound. Obviously I will be returning the original. Thanks for the replies!
