I have no idea.Where do the gains for walker units come from?
Sorry I was wrong... just had a look at our 2003 Lexion 440... it was called "Evolution". You are right, "Elevation" was a NewHolland term.
Not sure where this 4 cylinder thing is coming from, APS (virtually unchanged), cylinder (larger) impeller (much larger) rotors, chopper or not. Same number of components as old model.What do the 4 cylinders look like? Like JD Series?
Maybe right side is a door to up-plug the impeller without going in the hopper...ha haI am skeptical of the hype that surrounds most new models typically, and I am for this one as well. I often question just how good the "improvements" are. However, I will say a 24" impeller is massively different than before.
My #1 criteria for a new combine model would be grain retention and durability/reliability. Our old 740 is pretty good most of the time but can certainly be improved upon. I know they have done vast changes and improvements since ours was built in 2011, but I hope the new model is even more improved.
Who wants to be the first one to dig out a plugged 24" impeller! Feederhouse reversers have been the norm for about 30 years I'm guessing. I sure would like to see some type of reverser fitted to the new model...it really wouldnt be that hard to make it happen.
Looks like just more power, 643>790 = 8800>8900
