The ban is on the sale of the gasoline powered gear, not the use, folks.

That said, when I replace my ZTR in the future, it will be the last piece of lawn/landscaping gear I have that is still gas powered. I prefer the battery power, already went that way with everything else, and that's what I'll cut the grass with down the road, too. The only reason I've not done that yet is because what I have is paid for (in 2005) and I don't spend a huge amount of time mowing anymore, either. Major brand (example EGO) battery operated lawn mowers have "yuge" run times so I have no concerns about "battery life and charging". In the shops of the local purveyors of landscaping gear, the balance between gas/diesel powered gear and battery gear has taken a noticeable shift in the last year or so and yes, I'm talking about pro gear.
