I agree 100%. I don't see why they can't put a 36hp Vanguard on there Super Z, at least on the 72" decks. I can see that big of an engine being over powered for a 60", however.
I know last year when I was buying a 72" mower, I would have considered Hustler in my decision if they had a bigger engine option. Oh well.....
No longer in the lawn care business.
