Yes, commercial mowers are usually exempt. The overwhelming majority of lawnmower amputations are committed by a relative, mowing in reverse, on homeowner class machines. All it takes is a momentary lapse.



None of the ZTR mowers have the reverse to blade interlock, not even the cheaper ones at Lowes.


Yet.

Think about it...a rio switch requires a hand to operate. Where are your hands on a twin-stick, ZTR mower? With a steering wheel, you can remove one hand to activate the switch, while maintaining control with the other hand. But both hands are busy on a twin-stick.

But, it's coming. I am proud to say I was able to provide input on one such new device. I know they are a pain, but they do offer protection for the innocent from other individuals. I believe that is the purpose of such governmental intervention?

Full-on commercial mowers also do not have to comply with blade tip speeds. However, all ZTR's are not commercial units, not by a long shot.


"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
