[QUOTE="Two Tone, post: 7044303, member: 44728"] 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. 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. [/QUOTE]
