Most lawn equipment made nowadays are 4 stroke or electric. Which electric taking over. The problem IMO most lawn equipment used by landscapers have remove baffles in mufflers of leaf blowers making them twice as loud. The fine mash screens get carbon up and won’t let exhaust air out not letting blower to rev up, so they just remove baffles rather than scrape carbon off. It will take another 10 years or more when they ban gas lawn engine equipment cause take that long to wear them out. Electric blowers are not much quieter cause moving lots of air under pressure makes noise.
