Well... it looks ugly in photos but much better in person. I guess I should not have said "all new" as the basic engines, transmissions and frames carry over. The hood,(the scoop is functional!) dash and fender deck are new and the X749 does not have a replacement. Engine cooling and cleaning of those areas is much improved. 54" and 60" High-Capacity Mower Decks are now on the table - old 48, 54 and 62 mowers are gone. The new 60HC will work with AWS. If you are not familiar with the HC decks we have used them on the Z600 Series since it's inception. They are the same mold as the 7-Iron but made with 8.5 to 9 ga (depending on who you ask) steel instead of 7 ga. Great decks, we are glad to see them on the X700. These decks will be drive over like the 60" 7-Iron (which is also discontinued) but will have AutoConnect at least as an option - I didn't catch if AutoConnect was standard.
Interestingly enough, there is no John Deere "signature" anywhere on the machine, although I am told that was the original idea.
BTW J-Up was my instructor at the MoCo/Windrower outdoor class.
