The AFX is basically a specialty rotor with NH style auger up front to replace the IH impellers. They may have switched the location and number of bars, but it's quite similar to the Specialty configuration. We had a Standard rotor that we wanted to swap out, and I had a pretty tough time deciding between the Specialty, the AFX and the St. John rotor. Finally I decided to go with the St. John in a effort to get the best performance in our crops. I was more money than the Specialty and less than the AFX. I doubt I get a chance to run beside an AFX next year, but we have a specialty so that will be easy. I'll know more next summer! Anybody need a Standard rotor that is ready to just drop into an 88 machineIJ As for an AFX for $4000, that seems pretty reasonable. $3500 would probably seal the deal for me if I were in the market.
