How It Works: New Holland CR11
The New Holland CR11 is a 775 HP combine harvester designed around a fully redesigned Twin Rotor architecture aimed at increasing throughput, reducing grain losses, and simplifying internal mechanics. Developed at CNH’s harvesting center in Zedelgem, Belgium, the machine combines high-capacity crop flow, advanced automation, and a new drivetrain layout optimized for large-scale grain harvesting. With a 20,000-liter grain tank, unloading rates of up to 201 L/sec, and intelligent cleaning automation, the CR11 represents a new generation of high-capacity combine design.
System Overview
The CR11 is built around a longitudinal Twin Rotor threshing and separation system, integrated with a redesigned internal crop flow architecture.
The machine’s operating logic is based on four main principles:
Continuous crop flow
Reduced mechanical complexity
Automated cleaning and separation
High-capacity grain handling
Unlike conventional combines using a transverse threshing cylinder and straw walkers, the CR11 processes material through two longitudinal rotors that perform multiple functions simultaneously.
Crop Intake and Feeding System
The harvesting process begins at the header, which can operate with ultra-wide platforms designed for high-capacity harvesting.
How the feeding system works:
The header cuts and gathers crop material
The feeder house transfers the crop into the combine
Material is directed into the Twin Rotor system
Up to this stage, the operating principle is similar to other large combine harvesters.
The major difference begins inside the threshing and separation section.
Twin Rotor Threshing and Separation System
The CR11 uses New Holland’s Twin Rotor technology, although heavily redesigned for higher throughput and smoother crop flow.
Operating principle:
Two large longitudinal rotors process the crop continuously
Threshing, separation, and crop movement occur simultaneously
Material flows axially through the machine instead of transversely
Functional advantages:
Reduced grain damage
More uniform crop flow
Higher processing capacity
Lower grain losses
The axial design also allows gentler crop handling, particularly in high-yield conditions where material volumes become critical.
Longitudinal Engine Layout
One of the most significant engineering changes in the CR11 is the engine configuration.
The FPT Cursor 16, a 15.9-liter engine delivering up to 775 HP, is mounted longitudinally in alignment with the rotor angle.
Why this matters:
Eliminates several angular driveline components
Reduces the number of chains and transmission elements
Simplifies overall mechanical architecture
According to New Holland, the driveline contains up to 25% fewer components compared to previous generations.
This reduces:
Mechanical complexity
Maintenance requirements
Energy losses through the drivetrain
Grain Separation and Loss Management
As material moves through the rotors, grain is separated from straw and chaff.
The system was specifically engineered to maintain throughput under high-yield conditions without saturating the separation area.
Key design elements include:
Larger effective separation surface
Improved internal crop distribution
Continuous monitoring of crop flow
The objective is to minimize grain losses while maintaining stable processing performance across varying crop conditions.
Twin Clean Cleaning System
One of the CR11’s major technical innovations is the Twin Clean system.
System architecture:
Two upper sieves
Two lower sieves
Dual clean grain augers
Intelligent load sensors
The cleaning stages are arranged sequentially to distribute material evenly across the cleaning surface.
How it works:
Sensors continuously monitor sieve load distribution
The system automatically adjusts material flow laterally
Uneven crop loads are compensated in real time
This differs from conventional cleaning systems, where material distribution is more passive and dependent on gravity and airflow alone.
Intelligent Self-Leveling Cleaning System
The CR11 incorporates pressure sensors that continuously monitor load conditions across the cleaning shoe.
Operating sequence:
Sensors detect uneven loading
Hydraulic cylinders shift the sieve assembly laterally
Material is redistributed evenly across the cleaning area
This system compensates for:
Side slopes
Uneven feeding from the header
Variable crop flow conditions
The result is more stable cleaning efficiency under difficult harvesting conditions.
Grain Tank and Unloading System
Once cleaned, grain is transferred into a 20,000-liter grain tank.
Operational benefits:
Longer harvesting cycles
Reduced unloading interruptions
Improved field productivity
The unloading system can transfer grain at rates of up to 201 liters/second, among the highest capacities currently available in commercial combines.
The machine also offers:
High-speed unloading mode
Controlled slow unloading mode for more precise grain cart filling
Residue Management System
The residue management system was also redesigned to simplify material handling.
Key functional changes:
The chopper rotates in reverse orientation compared to conventional systems
Airflow assists straw movement through the machine
Conveyor components are eliminated
A single spreading system distributes residue
The spreader can distribute residue across widths of up to 18 meters.
Automated Residue Distribution
The CR11 uses sensors to monitor residue impact patterns behind the machine.
How the system operates:
Sensors analyze residue distribution on the ground
Wind influence and crop flow variations are detected
Spreader settings are adjusted automatically
The objective is to maintain uniform residue coverage across the full harvesting width.
Automation and Precision Farming Systems
The combine integrates the IntelliSense automation platform.
Automated functions include:
Ground speed adjustment
Cleaning optimization
Grain loss control
Crop flow management
All systems are managed through the IntelliView 12 interface, which centralizes:
Machine monitoring
Telemetry
IntelliSteer guidance
Precision farming functions
Remote visualization
Operational Logic in the Field
In practical operation, the CR11 functions as a fully integrated high-capacity harvesting system:
Crop enters through the header and feeder house
Twin rotors thresh and separate material continuously
Twin Clean manages grain cleaning automatically
Grain is transferred into the large-capacity tank
Residue systems distribute straw and chaff evenly
Automation systems continuously optimize machine settings
All subsystems are designed to maximize throughput while minimizing grain losses and operator intervention.
Analytical Conclusion
The New Holland CR11 represents a major evolution of the Twin Rotor combine concept, combining increased throughput with simplified mechanical architecture and advanced automation.
Its technical differentiation is based on the integration of:
Longitudinal Twin Rotor crop processing
Simplified driveline architecture
Intelligent cleaning automation
High-capacity grain handling
Automated residue management
Together, these systems position the CR11 as a combine designed for large-scale harvesting environments where productivity, crop flow efficiency, and loss reduction are critical operational priorities.
