Steiger Man - 12/24/2024 12:12 These new class 10/11 combines from NH, Case, and JD are physically larger in the threshing department. Remember you don’t have to go wider but you can go longer. I think the new class 10 axial flow has a rotor 3ft longer than the older rotor they’ve been using since 1977. The NH rotors in the smaller combines are 22” dia but I think these new ones are 24” dia same as JD X9. And I think they are substantially longer vs the older smaller CRs. You have a valid point when referring to the JD S series and smaller Case combines but these class 10/11s do have substantially more to threshing area. Just think of this, the X9 is more or less two rotors from the class 5 JD 9560/70 put together.
Yeah I don't know that I agree with all that. You can make them as long as you want but you have to be able to get the crop in the hole. If the hole isn't big enough for the crop to get in, it doesn't matter how long it is. A longer rotor gives you more time for threshing.
I don't know what this "hole" is so I am going to assume it's the rotor inlet. So what's easier to feed? Crop from a 45ft header feeding through 55" feeder house getting squeezed down into a 30" rotor or crop from a 50-60ft header through a 55" feeder house into two 24" rotors?
