I think a 470R is the same width of machine as a 570 and 580. The 470r would not have the Jet stream cleaning system, also the 470 doesn,t have the power louvers to blank off the rotors(need to put blanks manualy). The 400 series have smaller cabs, less electronics, and poorer choppers. The 480R is same width as the 590R. The 4xxR series is a very good combine.
