I *have* an electric lawn mower, think it is only 1kW or so,
the kind you need to push (or pull) what is the problem?
Now much snow here lately (last 10 years or so that I can remember),
eh make that last 40 year, eh make that last 60 years...
Oh well.

Those electric movers are OK, just plug it in and it works.
Cleaning it after mowing is most of the work.
