Oops!
I may need to eat my words. I picked up a new Grand L brochure today and Kubota has moved the fuel fill to the right side of the tractor. I didn't see one in person so it may not be perfect but it sure looks better than having it in the center of the hood.
Also they have moved the quick connect fitting for the loader from under the tractor to above the floor deck. No need to bend way over to take them off. Kubota claims I wouldn't even need to get out of the drivers seat to take the loader off any more. The loaders are interesting also. There is no frame that wraps around the front of the tractor anymore. Just two pins one on each of the main upright supports. Looks like a pretty cool setup.
Another big thing is the rollback angle on the loaders is much better than on previous models.
I also noticed that you can get a cab with AC/Heat and LIGHTS already mounted on a 3430....I think you had to go up to a 3710 to get a cab before....I might be wrong on that though.
Maybe Kubota has answered all my desires with the new models after all.
Hmmm, 3430, cab, mmm, loader....sounds pretty good.
