CLEANING

A steady flow of clean grain

The cleaning efficiency of the New Holland CX5 and CX6 combine models matches their high threshing and separation capacity. Large adjustable sieves, moving in opposite directions, and a powerful fan delivering an even distribution of air, are complemented by ingenuous extra features: the Triple-Clean™ cascaded cleaning system, the Smart Sieve™ concept that virtually eliminates side slope effects and the award-winning Opti-Fan™ system that adapts the air flow to the longitudinal slope of the combine.

Triple-Clean™ cascaded cleaning system

The standard Triple-Clean™ cascaded cleaning system boosts cleaning capacity by as much as 15%. This simple yet innovative feature enhances cleaning by means of an extra cascade in the center of the grain pan, where an additional air blast removes large volumes of chaff and short straw ahead of the main sieves. This triple cascade approach ensures cleaning is not compromised when overall machine capacity is being optimized. Further capacity improvements include the new double flight cross auger which transfers grain to the elevator faster and can result in a 10% increase in throughput of the grain elevator system on 6 strawwalker models.

Redesigned fan

The new Triple-Clean™ Opti-Fan™ has been redesigned to efficiently blow air through two outlets to aid cleaning on the sieves, and a new, third outlet, has been added to direct air between the two preparation tables.

Smart Sieve™: neutralising the effect of side slopes up to 25% both sides


• On Laterale models, the standard Smart Sieve™ system creates a lateral sieve movement directing the grain kernels uphill
• An even layer of kernels and an even air-flow over the full width of the sieves maintain maximum cleaning efficiency

Really smart: no radial swing on flat fields
• The ingenious system that controls the lateral sieve movement is governed by the degree of the slope. To avoid unwanted radial swing/movement it incorporates a linkage to the sieves pivot arm
• This patented concept neutralizes the radial swing and provides perfectly balanced sieve dynamics

Even smarter: automatic kernel size adaptation
The lateral sieve movement is determined not only by the degree of the slope: the fan speed, which depends on the kernel size is also taken into account to determine the optimal throwing angle.

Dealing with longitudinal slopes: the Opti-Fan™ system blowing precision

• The award-winning Opti-Fan™ system consists of a simple yet very effective way of correcting fluctuations in the speed of grain flow across the cleaning shoe
• Whether working up-hill or downhill, the fan speed automatically adapts to the direction and to the degree of the slope

Autofloat™ II system

• For maximum header positioning accuracy in rolling conditions, the optional Autofloat™ II system corrects the “exaggerated weight signal”
• Header bulldozing is avoided when working downhill and maintains correct stubble height when working uphill
