It’s only the sales of them. If you already one any gas powered thing you’ll still be able to use it. Plenty of them always for sale on CL, OU, FB, Nextdoor.
The first time they banned gas powered tools was blowers only because of the noise, dust.
But I think the ACLU represented the mow n blow guys and the need for their jobs.
Was a nice few weeks of them sweeping up the neighbors cuttings instead of blowing them into others. Biggest reason no one has a nice yard anymore, they blow the clippings and seeds into the yards of others. Resodding isn’t worth it anymore, you’ll have Bermuda and St. Augustine in a couple of months.
