The new JD ztr mowers should be hitting the dealers within the month. Saw them at a trade show in December and they look nice. The deck is the same, and I think the 7 Iron decks are on the top 3 or 4 decks out there (SCAG velocity, Exmark ULTRACUT).
The new ones are built more heavy duty and have better features.
I've got it narrowed down between the new JD and a Scag for my new mower.
