I saw it too and had a look. The rotor is different than the early 8570's and the body and the cab has changed. Has a Redekop (JD) chopper on it too. I was surprised to see what appears to be very little change in the chassis from the 8570 from under the new body workIJ Meaning frame, drive designs, feeding_transition area etc. Can anyone give the major changes_improvements to the unit from the 8570_8780XP days. Just curious
