Threshing and Separation

WORLD-CLASS GRAIN QUALITY

New Holland invented the Twin Rotor® concept over 40 years ago and has refined this evolving technology so that it delivers unmatched efficiency, capacity and grain quality. It’s also a design that is extremely flexible, making it easy to match a CR Series combine to various crops, conditions, and operations. New Holland also knows that no two farms are alike, so two different types and sizes of rotor have been developed to match farmer's specific needs. Seventeen-inch rotors are used on CR6.80, CR6.90 and CR7.90 models, while the CR8.90, CR8.90 Elevation, CR9.90, CR9.90 Elevation and CR10.90 Elevation models are equipped with the heavy-duty, high-capacity 22-inch rotors.

MORE CENTRIFUGAL FORCE

Twin Rotors generate 36% to 40% more centrifugal force than any other rotary design, moving the grain quickly for faster separation and maximum throughput. This faster separation virtually eliminates grain damage and loss.

GENTLE THRESHING, HIGHER QUALITY

A high level of grain-on-grain rubbing action releases grain quickly and gently—before it comes in contact with metal threshing components. This ensures gentle threshing with minimal damage; the Twin Rotor system delivers outstanding grain quality.

ENHANCED PRODUCTIVITY WITH DYNAMIC FEED ROLL™

The addition of the optional Dynamic Feed Roll™ system, which is located in front of the rotors, simultaneously speeds up the crop, for smoother, streamlined feeding, and automatically directs stones into a dedicated trap. The additional roll, available on all models except the CR6.80, improves feeder performance by up to 10%-15% thanks to greater throughput.

S³ ROTORS

New Holland’s standard “S³” rotors are Staggered, Segmented and Spiraled to control the crop, moving material evenly rearward without bunching and minimizing grain damage. The CR6.80, CR6.90 and CR7.90 feature 17-inch S³ rotors with two intake flights, while the CR8.90, CR8.90 Elevation, CR9.90 and CR9.90 Elevation feature high-capacity, 22-inch S³ rotors with three intake flights.

OPTIONAL TWIN PITCH ROTORS

The Twin Pitch rotors are available for more aggressive separation in difficult harvesting conditions where they can lead to a 10% increase in capacity. They are standard for harvesting rice and standard on the CR10.90 Elevation model. They are available as an option on all other models except the CR6.80.

CONCAVE FLEXIBILITY

Concaves and separation grates are easy to change if you harvest a variety of crops. Choose between the very finest small wire options for small grains right through to the round bar concaves and grates for corn and soybeans.

EVERYTHING IN GOOD TIME

You can precisely position the optional rotor covers with adjustable vanes to either accelerate or slow crop flow, adjusting the time provided to thresh and separate the grain.

STRAW PROCESSING

When the straw reaches the end of the rotors, the 15.7-inch-diameter straw flow discharge beater moves and accelerates the straw to the rear of the combine.
