They stretch this out and.. it's just horrible. I'm often away from the house, but my wife sometimes can't get away at home (they'll start in the middle of her cooking, for example). It bothers our pets - they'll be hiding under the beds for hours.
I get it - mow the grass. But... it really doesn't need to be 3+ hrs. One neighbor mowed for 2 hrs on Thursday. SUNDAY AFTERNOON he mowed for another hour. The grass was not longer. He just likes riding a mower. Next to our window. Then... edger/blowing. Another 30 minutes, and again... leave it propped up facing our window - running - to go in and get a drink. I'm not even sure how/why it's possible to have an edger running without a human holding it.
