New Holland CR - This is the gold winner
With the new double axial rotor combine harvester CR, New Holland is entering a new dimension of performance in double axial rotor combine harvesters with the longitudinal flow principle. (Image source: DLG)The further development of the technically possible threshing performance of combine harvesters is increasingly limited by their size, mass and geometry. This applies in particular to the widening of the threshing channel as the most effective design measure, which would have a direct impact on the machine width, which in turn is already reaching the limits of the legal transport width restrictions.
The basic, regressive course of separation functions speaks against a simple extension of the threshing and separating distances. In addition, higher drive power and appropriately dimensioned drive technologies as well as threshing and separating tools lead to the legally specified axle loads being exceeded.
The overall concept of the new double axial rotor combine harvester CR from New Holland was therefore designed for maximum power density while adhering to all restrictions. The core of the new CR combine harvester is the drive technology with the engine installed lengthways according to the inclination of the rotors. Rotors and harvesting headers with a feed chain are driven in a straight line or via a cardan shaft via the central, centrally arranged, power-split transmission.
The left rotor serves as a countershaft for the feed drum. The cardan shaft is located on the right side of the chassis above the level of the rotor housing. As a result, there are no drives between the chassis and the running gear on both sides of the chassis, which means that the chassis width has increased significantly.
The resulting free space serves to widen the threshing channel and thus increase the installed technical performance of the combine harvester. To remove blockages, a software-controlled automatic system not only carries out the usual back and forth movements to loosen the blockage, but also pivots the belt tensioner to the tensioning side of the belt of the feed drum, which leads to a particularly precise transmission of the rotary movement.
The patented cleaning system has also been widened by 13% and the grain elevator feed has been optimized, while pressure sensor-supported control technology measures the dynamic pressure and thus the crop distribution separately on the front and rear upper sieve. Defects due to uneven distribution of the mixture of grain and non-grain components are compensated for by lateral shaking, with which the system not only ensures an even distribution of crops on the upper sieves on the plane and also on the side slope, but can also correct the fundamental lateral distribution problem typical of axial rotor combine harvesters for the first time.
The straw chopping and distribution technology is equipped with camera-based control technology, which increases the energy efficiency of the combine harvester while at the same time keeping the machine mass almost unchanged thanks to mass-optimizing designs.
Hi all
Just a query on a combine we were considering purchasing if anyone could help
It’s a new Holland cx 880 with approx 3500 drum hours
What’s advisable to look out for with these hours done and what should be replaced by now
Would we be better with something with higher hours that has had more refurb done by now or is this ok
The website mentions that it will be the 50th anniverdsary of the twin rotor concept in 2025, but to me gives no launch date for the 11.90. i would have thought after this years testing across multiple nations which must have involved at least a handful of prototypes, there would be an intitial placement of models onto selected farms next year, especially as there will be a formal launch on November 12th
