This is an electric mower. It runs but emits a rhythmic noise. There's a link at the bottom to an imgur file with a .MOV video.
It was given to me recently; I just tried it yesterday and got this noise. I bought an electric back in the 1970s and used it for 40some years. Trashed it when I ran it into a tree root and (I think) bent the motor shaft.
Harmonic ringing on an electric mower is normally caused by either a blade which is unbalanced or a motor going bad. I would remove the blade and run the mower. Noise gone blade bent or unbalanced. Noise still there, motor going bad.

I bet you won’t get 40 years out of this new electric mower like the one from the 70’s. I assume by electric you mean battery now. You will be lucky to get 4 years before you have to replace the battery.

A friend bought a new mower and gave this one to me when the noise started. I never got around to asking how old it is. I took it because electric mowers have very few moving parts, and sometimes I can fix things. The old one had the motor sitting right there on top of the deck and very easy to get to. This one is completely enclosed in a plastic housing, so I have some work to do just to get a look at it. The plan is to take the motor out and look at the bearings. If they're bad and I can get replacements, I'll continue; otherwise it's for the dump.
I'm doing this because some of you guys told me that my riding mower is about to blow a head gasket. I don't see myself fixing that.
Thanks, guys; this is the most helpful forum that I know about.
