I just thought i'd share some information that i've learned about the new ZD series. They have new styling, there is much more hydraulic flow through the transmissions at lower pressures for better reliability. They also have a higher ground speed, i'm guessing maybe 12-13 mph, and a deeper deck. I don't know if its a totally new deck design or the same deck thats just deeper. There is a sizable price increase for the larger ones but the smaller machines will stay about the same. I also found out that Kubota has a 60% market share in diesel ztr's. Thats according to kubota. Thats pretty good considering all the competition.
