Cr new Hollands in uk conditions

[dug]

I am posting from nz and was wanting to hear how the likes of the cr 8080 or 9080 were performing in your kind of crops. How would they compare to say a case ih 7120 and also is the straw quality really that much better than the single rotors?

 

[Mdt]

We have a nh cr9080 and its performing very well for us in w barley, w wheat and rape. The straw quality is good too and is much better than that from a lexion 570+.

Thanks for the reply, by all accounts everything I hear or read about the cr 's is good, excepting of course that some prefer the big hybrids. Considering that they are a relatively simple design like a simple rotor are they that much better? Apparently you can get the rotor speed up to 1700 rpm in tough conditions and still produce good straw. Also do you know how they perform in maize?

 

[Mdt]

Sorry cant help regarding maize. Yes its a very simple combine mechanically. Cant remember the speeds ran the rotors at but sure it was nowhere near 1700rpm.

 

[Bumble Bee]

From memory, I think that the rotors on our 9080 elevation run up to 1400rpm.

Hi

From NZ also originally had an Case 9120 with small tube rotor and it would not do wet oats with out plugging the concaves

Demoed an Lexion 770 with an Claas 10.5m front, we had 10.5m draper front and the lexion was 20t/hr more than us and we had to stop occasionally to clean out concaves

@dug there is an contractor with an cx cr and lexion 580, 580 does hard to thresh crops and nh do the easy ones

If doing just grain then Lexions far in front due to more metal to thresh grain against

Hi

Cr total rotor length is about 2.6m I think 1090mm for seperation and about 770mm is for threshing, concave wrap of 123 degrees. Diametre of 0.6m

Lexion 4.2m separation rotors but only about 3.6 usable unless you look at 780 which has more seperation area. Threshing area of 1.06 sq metres wrap is about 140 degree

Mdt and bumblebee the people I know of have a cr with the 17 inch rotors so maybe that's why they were talking higher speeds on occasions, just trying to get a handle on whether or not the straw is significantly better than out of a single rotor.

Combineguy thanks for the feedback, currently got a 7120, reasonably happy with job it does although the straw quality has not been as good as expected especially for a st rotor. Been doing a little homework for future to see if we can do better with a cr....... Been trying to avoid going the lexion way due to perceived issues.

This is some wheat straw from our 9080 last season.

Its not the rotor you are damaging it with, its the slow running chopper throwing it that you have that does it, the CR has a belt conveyor.

Running a CR980 against a demo small rotor CR9070 a few years ago I would not have a small rotor CR if you are worried about straw quality. The difference between the 2 was huge. We bale plenty behind the 980 with no problem.

Hi

What are your percieved issues with an Lexion?

Lexions arent that hard on straw if set up correctly.

Lexions have a conventional drum with two rotors instead of walkers

Did the diameter change from the 900 to 9000 series then?

 

[Bruce Almighty]

980 has a bigger rotor than a 960

The 9070 did have a small chassis and 17" rotor untill 2012 adblue when the 9070 went to the same chassis as 9080/9090 wide body 22" 8060 and 8070 are small chassis and rotor

New Holland talk about crop on crop threshing with CRs and to do this recommend a 'high and wide' setting meaning high rotor speed and a wide concave. Once the straw has passed through the rotor that's it and its out the back. This is why they are so gentle on the straw. The other benefit of this is they are extremely gentle on the crop itself and you very rarely get many cracked grains in dry conditions, unlike other more aggressive threshing systems including CXs. Maintaining rotor speed is important and as always power is king especially with green straw and the bigger the rotor diameter the better.
