I believe there are only limited, mostly cosmetic differences between the N and R series. The R's still used the Allis engines. I think they were lengthened out and perhaps had longer unloading augers. You have to go to the R50, 60, 70 to find anything substantial such as the Deutz engines and a Hawk Series 60 and 70 to see the P3 processor.
