The one I have is pretty quiet and perhaps the battery needs to be replaced? Or the blades - you are probably right. I was surprised by how easy it is to sharpen blades with a rasp. Of course, I think the mulching blades I still bring in. The shape is beyond my skillset.
I never thought I would like an electric mower, but, I can see how awesome they are and so much better for our environment.
Happy Sunday!
