My 12 year old corded electric push mower. When you have a small yard like we do, you don’t even need a battery model, just learn to lasso the cord like a cowboy and be on your way. The best way is to start nearest the power outlet and go back and forth away from it.
It’s quiet and needs almost no maintenance, just change the blade sometimes.
It’s not as powerful as a gasoline mower, so you can’t let the yard grow up that much. When it spirals out of control, we have to call somebody.
