I voted yes, specifically on the premise of "liability" and "protective" measures that I feel are in the best interest of a professional lawn care maintenance worker, their family, the owner/license holder(if applicable) and would include mandantory wearing of the seat belt. Now do I want a police officer to observe me(or you) mowing our personal property without the same enforcement.....that's a hard one(I am answerable only to myself and family....NOT a paying customer that my wife could sue, along with my boss). And, I believe a dealership(and manufacturer) has some accountability if a ZTR is "sold as" a commercial ZTR(or in the case of my Gravely has "Commercial" plastered across the front of it). I understand the ramifications(cost-wise for equipment) this puts on start-up commercial individuals, but like most enforceable "laws" many end up as being forced to comply with that business' regulations(debateably whether in their best interest). They already have to adhere to DOT regulations regarding the trailering requirements of their equipment(mandantory tie-down, GVWR specs of trailer, etc.). Many will despise me for even bringing this up(yes, I am the OP of the thread mentioned by X-man) but IMHO this is the "elephant in the room" to quote therapy notations of a problem being "ignored" rather than confronted that forums like this just do NOT want to talk about. I knew it would stir up a hornet's nest.....Sorry:0(
