Zep, I'm sorry but I haven't any experience with those types of decks on ZTR's. I am intrigued though, and have often wondered how they compared to the rear discharge tractor type decks we used to see. After getting my right ear canal plastered full of clippings yesterday due to windy conditions, I can sure see a place for such a deck!

"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.
