• CR10 model joins Agritechnica-previewed CR11 at new range’s official launch
• CR10: 635hp/16,000-litre grain tank – CR11: 775hp/20,000-litre grain tank
• Both models feature new 2x24in rotors and new Twin-Clean cleaning system

The new flagship New Holland CR11 combine previewed at Agritechnica 2023 has been joined by a CR10 companion model at the official harvest 2024 launch of the new Next Generation design, with both harvesters – built at New Holland’s combine Centre of Excellence in Zedelgem, Belgium – featuring innovative new technology designed to help the largest farming enterprises maximize output, minimize losses and reduce total cost of harvesting. 

The primary difference between the two models is in power and grain tank size, to ensure the new combines match the needs of a broad range of large farm enterprises. The CR11 features a 20,000-litre grain tank and a 15.9-litre FPT Cursor 16 engine producing 775hp. The CR10 engine is a 12.9-litre FPT Cursor 13 generating 635hp, while its grain tank holds 16,000 litres. Beyond additional power and grain capacity, the key features that take these combines into a new league in terms of output, sample quality and loss minimization include longer twin rotors and the new Twin-Clean cleaning system.

More capacity from front to rear

From the front, these new flagship CR combines are designed to handle greater volumes of crop. Cutterbar widths of 10.6-15.0m (35-50ft) are available in fixed, flexible knife, movable knife and draper formats. Corn/maize heads of 12-16 rows are also available, and unloading auger lengths can be specified to match all header widths. There are three driveline options to meet all header requirements – standard with fixed drive, standard with variable drive, and a variable heavy-duty system. On the variable driveline, a CVT drive unit on the engine gearbox allows header/feeder speed to be varied depending on crop and field conditions. Feeder/header reversing is achieved via with a hydraulic motor on the fixed speed driveline, and with the CVT drive on the variable speed driveline. 

The elevator is equipped as standard with front face adjustment and lateral tilt remote controlled from the cab. From here the crop is fed to New Holland’s proven Dynamic Feed Roll system, which can now be reversed – simultaneously with the elevator and the rotors – in the event of a blockage. The DFR accelerates the crop and splits it into two even streams to feed the two longitudinal threshing and separating rotors that follow. A large stone trap in front of the DFR can be emptied either manually or, optionally, remotely via hydraulic activation from the cab.  

New Holland was the first to launch a combine featuring two longitudinal rotors at its heart, pioneering its Twin Rotor threshing and separation technology almost 50 years ago, in 1975. Over time, its design has evolved to ensure it meets similarly evolving demands for throughput, grain protection, grain retention and straw quality. In the new CR10 and CR11, the two 600mm (24in) rotors are of increased diameter and length, providing greater capacity for the crop to circulate and the grain be be threshed and separated. Each rotor features 40 standard rasp bars, eight HX raspbars and 12 spiked raspbars. The HX units combine the height of spiked raspbars with the profile of the standard units, with a greater sidewall angle helping accelerate crop flow in the transition zone of the stepped rotor cage, between the threshing zone and the separation zone. Vane angle can be remotely controlled from the cab, and the new vane design aids crop ejection should the rotors need to be reversed. New rotor cages feature a stepped design with a broader cage and higher vanes in the separation area, to allow greater crop mat movement, improved separation and enhanced power efficiency. The concave area comprises two sets of three lightweight threshing concaves and separation grates, and two sets of six lightweight grates.   

All-new TwinClean cleaning shoe

The new TwinClean cleaning shoe incorporates multiple features to boost throughput and minimize grain loss. It consists of two sieve systems in sequence, each having its own upper and lower sieve and clean grain auger, and is based around a large grainpan with an increased fallstep to the first upper sieve. Airflow is provided by a high-power cleaning shoe fan. Two automatic cross distribution mechanisms, one on the grainpan and one on the upper sieves, guarantee an even cleaning shoe load in all conditions. Two sets of pressure sensors, one on the grainpan and one on the upper sieves, continuously measure the cleaning shoe load and detect any anomalies in material distribution between left and right. A side-shake mechanism adds a lateral component to the grainpan and sieve movement which evens out the material over the cleaning shoe’s full width. As such, the cleaning shoe can compensate for uneven feeding and side slopes up to 28%. Overall size of the complete sieve area is 8.76 m².

Grain tanks that maximise autonomy

The CR11 grain tank holds 20,000 litres, with an unloading rate of 210 l/sec, while the CR10 tank holds 16,000 litres and has a 159 l/sec unloading rate. Cross-auger shut-off allows the unloading auger to be fully emptied even when the grain tank still holds grain. On the CR11, an option allows unloading speed to be reduced by 50% by disengaging the front cross auger, aiding topping-off of trailers. All unloading augers feature a pivoting spout, to aid even filling and allow tractors to keep on track. 

Residue management to match big cutting widths, high straw volumes

CR10 and CR11 combines can be equipped with either a standard integrated chopper or a high hood-mounted fine-chop unit. While the first of these is intended for dry conditions, the high hood-mounted unit is targeted at users needing to process high straw volumes to a fine chop and distribute material across a wide cutting width.

The standard integrated chopper features 60 fixed blades which work in conjunction with 52 counter knives working at 3,000rpm for chopping, or at 800rpm for straw swath laying. Manual adjustment of the counter knives is standard, and remote hydraulic adjustment optional. A driven roller assists straw ejection when swathing, or into the spreader impellers when chopping. The two hydraulically-driven 800mm impellers, each equipped with three paddles, spread chopped material at widths up to 15m (50ft). An oscillating deflector behind the spreaders creates a dynamic pulsating effect on the residue spreading to ensure even distribution over the full cutting width.

The high hood chopper option leads with a 500mm beater with two rows of spikes and tworows of blades, plus a non-perforated beater pan. This is followed by a six-row chopper with 88 flail knives and 67 counter knives. The chopper can operate at low (900rpm) or high (3,600rpm) speed, with a neutral position for free movement when servicing is required. Remote chopper speed selection is optional. The pair of hydraulically-driven 970mm-diameter impellers on this unit each feature five paddles, capable of distributing material at up to 18m (61ft). As on the standard unit, an oscillating deflector is again fitted behind the spreaders on the high hood chopper, to dynamically pulse the residue across the full cutting width. The IntelliSpread option uses radars to continuously assess the full width of the residue spread and automatically adjust left and right spreader speed to guarantee full width spreading. Further options include remote selection of chopper door position, chopper gears and counterknives. Also optional is a chopper load indicator, which  provides information on chopper power consumption, allowing chopper power efficiency to be assessed in relation to chop length so the operator can select the optimal balance between power consumption, chopping quality and throughput capacity.

Technology plus comfort for an easier harvest

The CR10/CR11 cab, which sits beneath new roof styling and has a 25-litre handwash tank with integrated soap dispenser located by its access steps, features multiple upgrades. Operation is made easier through incorporation of twin Intelliview 12 touchscreen terminals. With the primary monitor on the right-hand console providing management and monitoring of the combine’s key controls, the secondary monitor on the A-pillar is configured for mapping and guidance. Both combines are equipped with three cameras, providing views to the rear, of the grain tank and of the unloading auger spout, while a 360° bird’s eye view camera is optional, as is a trailer hitch camera. Either monitor can be configured to display external camera views. The operator can now also fully control more functions remotely from the cab, including the speed of the rotors, chopper and unloading auger, reversing of the DFR and rotors, and full engagement/disengagement of the straw chopper.

Elsewhere in the revised cab, changes include new-style brake pedals and foot pegs, a luxury steering wheel and premium cloth or leather seats, plus new multizone climate control with floor level air ducts. A new Bluetooth radio allows operation of the radio and a mobile phone via the radio control panel in the roof liner, or one of the IntelliView 12 touchscreens. Externally, new mirrors provide a wider view angle, with the right-hand unit optionally electrically foldable, while windscreen access steps aid glass cleaning.

A comprehensive lighting package includes four LED beacons (two at the front and two strips at the rear), 13 cab-mounted LED worklights, two stubble LED lights, one unloading auger LED light, one graintank LED light, eight rear LED worklights, two LED sidelights, three undershield LED strips, two engine service LED strips and an LED sieve strip. Optional ‘far distance’ lights of 36,000 lumens with 500m reach can be integrated under each of the cab roof wings. There is also an additional portable worklight.

Precision to match performance

New CR10 and CR11 combines are equipped with precision farming technology packages designed to match the needs of the largest farms. A Core PLM Intelligence package covers the most commonly-specified requirements, such as IntelliSense, where automatic adjustments occur according to the harvest strategy chosen by the operator, whether limited loss, best grain quality, maximum capacity, or fixed throughput. The second option is an Advanced PLM Intelligence bundle, aimed at those with the most advanced demands.

Correction signal packages for IntelliSteer automated steering and other functions such as yield and moisture mapping are available from the factory in two accuracy levels with three delivery options. 

Via the optional IntelliField software, at no cost owners and operators are instantly provided with in-field data and can share boundaries, guidance lines and coverage data where multiple machines are operating in the same field.

A drivetrain to match the most demanding conditions

The CR10 and CR11 feature a two-speed hydrostatic transmission and TerraLock semi-automatic diff lock which is engaged manually and disengaged automatically depending on steering angle and forward speed. Models specified with SmartTrax are available with three track belt width options of 660mm/26in, 810mm/32in and 910mm/36in, with rubber or hydraulic cushioning. Respective overall machine widths are 3.49m, 3.79m and 3.99m. For certain markets a wide beam configuration is available in combination with 910mm/36in tracks, with an overall machine width of 4.8m

Where a wheeled machine is preferred, New Holland and Michelin have co-developed 900mm-wide tyres of 2.32m diameter (VF 900/65 R46), to minimise compaction and maximise traction. Alternatives tyre options are VF 800/70 R46 (2.32m diameter) and VF900/60 R38 (2.05m diameter). Rear tyres on both wheeled and tracked combines are available in widths from 500 to 750mm. Other options include 710/70 R42 or 800/70 R38 duals, and LSW tyres up to 1400mm wide.

The engine in the new CR10 is a turbocharged six-cylinder 12.9-litre FPT Cursor 13 fed by a 1,300-litre fuel tank, while the powerplant in the CR11 is the 15.9-litre FPT Cursor 16, also a six-cylinder turbocharged unit, with a 1,500-litre fuel capacity. Respective maximum power outputs are 635hp and 775hp. A new design layout sees the engines installed longitudinally in the same direction and at the same angle as the rotors, for maximum efficiency, with cooling air being drawn from behind the grain tank. The CR10 features two cooling fans, with three on the CR11. All exhaust manifold/turbo/after treatment installation is full isolated to reduce surface temperature of hot components. Harvesting engine speed is 1,900rpm, resulting in subdued noise and minimized fuel consumption. In road mode, engine speed is 1,300rpm, for maximum travel speed with minimum fuel consumption and noise.

All drives are taken via a transmission connected directly to the rear of the engine, minimising power loss. The engine oil filter is sited on the engine’s right, for easy accessibility, while the air filter is located conveniently at the left side of the combine frame, and can be removed from the ground without climbing to the engine deck.

An optional engine air compressor comprises an engine-mounted single cylinder compressor and reservoir with 10m coiled hose and air gun stored next to the tool box. This supplies five outlets, located at the cab door entry, below the operator platform, next to the battery box, in the engine area and at the rear ladder. Engine accessories include brushes installed on each rotary dust screen, providing continuous cleaning in heavy dusts produced by crops such as maize/corn and sunflowers.

On the all-new hydraulic system on CR10 and CR11 combines, hydraulic hose routing has been redesigned in dedicated routing highways to improve access and simplicity. All harvest hydraulic drives are disengaged mechanically via a clutch in the main engine gearbox at start-up or during road travel, reducing drag and saving up to 20hp/15kW of power. The use of load-sensing pumps further reduces hydraulic power demands and improves efficiency. Oil filtration has also been enhanced throughout the hydraulic system for increased reliability and reduced maintenance.
