Just got a cabless 4720 with a 400x and love it. E-Hydro is standard, as is loadmatch. Bought it used (2005 with 350hrs), so isn't exactly the way I want it, but all options can be added after. I probably would've got the 400cx loader, but I moved some dirt yesterday with the 400x and the standard (not heavy duty) bucket and was very impressed. Lot's of power, fairly quiet, good on fuel, looks good.
Going to add full automotive style cruise now, and top n' tilt if needed. Getting a bale spear for rounds, a minimum 72" rear mower deck, likely a landscape rake, a
ballast box to counter the bales, fluid in the rear tires, a toothbar for the loader.
Mine has the R1 'Ag' style tires, which I was happy with based on others feedback on the forums. The R4 industrial size look better and are easier on lawns, but wouldn't have pushed/pulled through the dirt that I did this weekend. I'm a little worried about mowing my nice lawn with it, but we'll see what happens.
Kubota is also excellent value if you don't want to spend the $$. I've wanted a green tractor since I was 3, and now I'm 30, so I spent the extra dough!!! You'll get it back in resale if you do go green.
Hope that helps.
