axial flow coming in yellow now ?

It’s here at last. I’ve known they have been working on it or a while. I remember talking through the idea with them as far back as 2013. Testing 2 years ago proved to be far better than was initially expected! There was one running in the UK last year in CX 6. livery.

It makes perfect sense because without a parallel drum in front of the rotors, it is very difficult to predict exactly which parts of the grain pan are going to be loaded with most of the grain, because different grain moisture will alter exactly where most is thrashed along the rotor and could mean that more grain hits either the sides of the grain pan or the middle of it. This will cause uneven loading across the sieves. NH realised this a long time ago and fitted the triangular hill plate above part of the grain pan of the CR’s to try to avoid this, which at best was a compromise because it will never be in exactly the right place for all crop conditions.

The only way to provide a more even Loading of the sieves is to do the majority of grain separation using a conventional drum, to ensure that the grain pan, then sieves are more evenly loaded.

But of course Claas have been doing this for ages! I think they first used it on their Tucano Hybrid.

The single rotor Case/IH’s can potentially suffer from even more Uneven sieve loading, which is why NH claimed that the original inventor of the longitudinal Rotor went to them with the twin rotor idea.

The TF lives!

You are quite right! This in effect is the true replacement for the TF.
When NH stopped building their old TF, they said that they only wanted 2, not 3 ranges of Combine and that they had gone about as far as they could with the TF, not wanting to make the TF rotor any wider than it already was in the TF 46/78.
So they dropped TF, started building all the CX’s in Zedelgem, Belgium and the CR,s in the USA. The trouble was that the early CR’s were not reliable when used in Europe, so Zedelgem persuaded NH to allow them to also be build in Belgium.

Thats a lexion 480 setup
Since 1995
Long before the tucano

I stand corrected (But was it a true drum or an APS?) Makes me wonder why it took NH so along to catch up on such an obvious solution.
But sometimes manufactures get stuck on what they think is the best idea and are loathed to change, in case it looks like they are admitting they were wrong!

 

[Flat 10]

So CRs are single rotor? Or twin rotor with no drum in front?

Lecion has an aps drum as well before thenormal drum
NH had to wait for patent to expire?

 

[glasshouse]

Claas prob had to wait till 95 for the nh tr patent to expire

 

[glasshouse]

Being a man of straw, i hate all rotaries

 

[Two Tone]

CR’s are twin rotor with no drum in front.
Case IH Axial Flow are single rotor With no drum in front.
CH’s are twin rotor with a drum in front.

 

[JJT]

so where will they fit in output wise, above the CRs? If so will they still bother with the CRs?

 

[tractor_lover]

The CH will be based on the small CX models (CX 6) and will be a competitor of the Claas Tucano 570/580 not Lexion.

Marketing own goal by New Holland?

What's it like on price, cheaper than an equivalent CR/CX?

 

[snarling bee]

I cannot see the point in making a hybrid smaller than then current CR range.
Lots of unnecessary cost, complexity, and weight.
In terms of CR they have probably gone as far as they can with output, same the Axial Flow, so perhaps this is to test the water prior to introducing a bigger range and phase out the CR.

Just above the CX6 and below the CR7.

The new Cr is probably the one that appeared covered in spy photos a few weeks ago.

In terms of output, the Tucano 480/580 punch well above their weight. The Axial Flow is not comparable, we've had them back to back here on demo and we went with the 480 despite being a happy former owner of a AF1680. I wanted the Case, but couldn't go past the hybrid Tucano.

Is that the CR11.90

11.90? are you sure?

NH have been experimenting with the CH idea in South America for a while, where the larger, more expensive CX and CR’s aren’t so popular. The CH is described as a “Pocket Rocket”.

The Limiting factor of any Straw walker Combine is the Straw walkers. This was how and why the TF was originally developed.

The Dual Stream Project also proved that by reducing the amount of MOG work the Walkers needed to do, lead to a dramatic increase in performance and the allowed the Sieves to run at maximum capacity on a CX. But wIth the CR, it only gave a minor increase in capacity.

So this why the CH has been developed. To provide a very fast, High capacity, small, light weight, cheaper Combine.


With regards to the numbers:
The CX 6080 is rated at 25t/hr in wheat.
Add a DS and that raised it to 37.5t/hr

Cascade triple sieve pushed the output of a CX 6.80 Elevation to 27.5 t/hr, but was never tried with DS. It was suspected that if it had been, 40t/hr.

The CH, which is based on the CX 6, but with Rotors instead of Walker also has a capacity 40t/hr.
