I know this is irrelevant, but I feel compelled to ask: What kind of mower is it?

I'm glad no one was hurt. I think your pond will be fine, especially if they're removing it this afternoon........hard to say about the mower itself, though. I've had a few in that condition come through the shop.

"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.
