Thanks for the replies. And for the record, I don't like some of the safety switches either.

Hey...what about a lanyard you wear around your wrist, like on a PWC?? Might not work for a small lawnmower, but on a tractor it would let you stand, but still kill the engine if you fell off?

"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.
