I don't see an economical advantage for big machines, generally. Nonetheless, for small machines, it seems do-able. However, though, even in this world gasoline shortage, $2 can still mow most of my big lawn, if not all of it.
Your advice is best for moving over Solar, however we see lawn-mowers are running on petrol, electricity. I understand, but here we use some hours of lawnmowers only and still people are not yet moved over Solar.
