I thought this already happened?

I kept seeing YouTube videos of people reviewing electric chainsaws or snowblowers or whatever and apologizing to their core audience that they weren't woke Democrats, it was just a better tool for many uses.

This definitely happened, all my yard/lawn items (mower, chainsaws, hedgers, etc) are all battery. So much better.

I can see a hedger working - even with a klunky battery making it a bit unwieldy. But chainsaws and mowers need serious torque - don't so don't they need to stay plugged in while you work ?

There are some decent battery electric mowers and chainsaws that can be great as long as you have the batteries to keep them going long enough.

I have an Ego pushmower. It takes like 2/3 of a charge to mow my lawn, with a 4 year old 5 amp hour battery.

I'm not saving money over gas, but I'm not spending a whole lot more and the lack of hassle is fantastic.

If I had a bigger yard I would hesitate to have lots of batteries or whatever.

I also have an EGO mower, and in addition to the advantages you list, I would add that they’re less noisy and you don’t end up breathing exhaust fumes. I don’t even understand why anyone would use a petrol mower at this point, except for some edge cases like professionals mowing multiple lawns per day.

My father originally had a 100% manual lawnmower, and for the size of our property, it wasn't really bad; my father is a physically fit dude, and he could knock out the whole thing in a short period.

Then in the late 80s, he purchased an electric lawnmower! Yep it wasn't battery-powered, but it had a little AC cord that you plugged in... somewhere! So Dad would just run a ginormous snake of an extension cord out across the lawn.

Now, our property wasn't large, but to reach an AC outlet, we really needed a lot of cord, and of course it was a key skill to not run over your own cord, like when you're vacuuming.

Dad never got anything gas-powered. He also had an edger that was electric, IIRC, and he made a lot of use of this edger. It was one of those kinds that used a fishing-line type cutting edge.

But he kept that machine around, and I guess it was fine for a very long time. Dad and Mom are old enough to employ a landscaping team, nowadays.
