I asked myself, should I sharpen my mower blade?

Yes! Sharpen it. I'd noticed a slight vibration and change in the sound of the mower after the last mow. I hit a piece of a root or a 1" stone (or both) and it sounded different after that. I didn't have much left to mow so I went ahead and finished.  The blade was somewhat dinged because I hadn't sharpened it since I got the mower, about 9 months ago, but only about 4 months of use plus that last incident. Anyway, I bought a Smith's  sharpener and gave it a go on the blade. Took around 30 passes total on each end of the blade and also a little bit with a flat file on the flat side of the blade. I also made sure it was well balanced. But it looks pretty good. Mowed again today and mower is quieter and smoother. Maybe even a bit more suction? It bagged really well.

My dear friend.  That vibration is a bent motor shaft.  Welcome to my world.  My mower gives me an arm massage every time I use it and if I try to talk, it sound's like my whole body is a vibrator.  It's my own fault for hitting so much crap, but it's not something a larger shaft gas mower couldn't normally handle. 

Still love the mower, I'm just not much for treating lawn tools any less gentle because they are electric.

I didn't read your comment completely.  I wish a new blade solved my problem.  lol.

Yeah, it isn't a bent shaft. I think the blade was just a little bit out of balance after that last strike. Whatever I ran over got kicked up inside and the blade whacked it around a couple times and I think that is what changed things. The vibration was so subtle. Just different from what it was before. Getting the blade back in shape took care of it though. It may even sound, and feel, better than when it was new. Although, that is probably just faulty memory.

I can verify that.  As the vibration got worse from hitting everything and anything, the mower gets SUBSTANTIALLY louder. 

I miss the quiet.

if nothing else, it keeps one's grass from getting unsightly brown ends.
