Dan; I'm going to attempt to answer your questions on the new CNH 8010. The rotor (AFX) is the same as the one in the current production 2388. The HP requirements were taken care of by using a 10.3 liter 375 hp (vs 285 hp) engine with a 25 hp bulge also a 40 hp boost while unloading. It would max out @ 415 hp. The concaves and separator grates wrap 180 degrees now instead of 130 in the 2300 models. The cleaning area was increased from 7,947 sq in to a self-leveling 10,075 sq in (same as CR 970 NH). Advertising says it is 40% larger than the 2388. It seems as though grain tank size and engine hp determine class size, so this is called a class 8. Also it is heavy at 36,000n. Not trying to start anything, just relating what's already in print.
