I have a 2010 3520 cab tractor which still looks brand new witho over 1000 hard hours. Was tossing around the idea of upgrading to the bigger 4 series. It was until i sat in a new one and siad to my self, "dam", this thing is the same as it was for 15 years now since they came out with the 3 series cab. Thats kinda piss poor imo. And to ad, the loader cables are still operated by the use of cables to the valve body. I hate that. Why do they not have the loader controls electronic over hydraulic? That setup does not cost much at all for added costs. SO yeah, the same damn cab for over 15 years and still same crappy loader cable controls is piss poor on john deere. When can we see a complete make over. ITs been long enough.
