This topic is crazy. That would be an unenforceable law. Just look at the points brought up in the first few points. You can't use laws to single out particular groups of people. It would be discriminating if you only ticketed lawn care professionals. Just because one mower has seat belts and a roll bar and another doesn't how could anyone justify ticketing the mower owner who had the safety equipment. If there were laws passed to ticket people from removing safety equipment then the law would also have to require all new mowers built (tractor or ztr, commercial or residential) have the same safety equipment. The equipment is on there and is recommended to cover the manufacturer in case of lawsuit. The law would never be passed on the state or federal level. There maybe some crazy city governments who would pass a city ordinance for something like that. In that case enforcement would fall onto the city's police department. I have seen some crazy ordinances in my career in law enforcement ( example: an ordinance against leaving garbage cans near the curb. Luckily I don't work for a city department anymore), but that one would top them all.
