Use a mulcher and/or run the mower with the shoot toward the inside of the mowing pattern. Problem solved.
Sorry, that doesn't work for us suburbanites who have patios and pools and are too busy with our jobs and making an honest living. Even I get annoyed by the constant noise of the leaf-blowers in my neighborhood, but I understand that all are at work during the day. If they can afford mov&go, and prefer to enjoy their weekends, more power to them.
Screw the noise-nazis. If they don't like it, let them move to a rural area or shut their damn windows or get ear plugs. Noise is a fact of life in suburbia - think car traffic. During the summer with the bedroom slider open, I sleep with earplugs. Sleep great.
You’ve got me convinced. But then, I do my own yardwork (one of the few around that do). The landscapers and lawn services are the ones who use that technique. Show up, lot of noise, gone to the next job.
