Basildon, June 2024
The new flagship New Holland CR11 combine previewed at Agritechnica 2023 has beenjoined by a CR10 companion model at the official harvest 2024 launch of the new NextGeneration design, with both harvesters – built at New Holland’s combine Centre ofExcellence in Zedelgem, Belgium – featuring innovative new technology designed to helpthe largest farming enterprises maximize output, minimize losses and reduce total costof harvesting.
The primary difference between the two models is in power and grain tank size, to ensurethe new combines match the needs of a broad range of large farm enterprises. The CR11features a 20,000-litre grain tank and a 15.9-litre FPT Cursor 16 engine producing775hp. The CR10 engine is a 12.9-litre FPT Cursor 13 generating 635hp, while its graintank holds 16,000 litres. Beyond additional power and grain capacity, the key featuresthat take these combines into a new league in terms of output, sample quality and lossminimization 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 volumesof 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 threedriveline options to meet all header requirements – standard with fixed drive, standardwith variable drive, and a variable heavy-duty system. On the variable driveline, a CVTdrive unit on the engine gearbox allows header/feeder speed to be varied depending oncrop and field conditions. Feeder/header reversing is achieved via with a hydraulic motoron 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 remotecontrolled from the cab. From here the crop is fed to New Holland’s proven DynamicFeed Roll system, which can now be reversed – simultaneously with the elevator andthe rotors – in the event of a blockage. The DFR accelerates the crop and splits it intotwo even streams to feed the two longitudinal threshing and separating rotors thatfollow. 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 itsheart, pioneering its Twin Rotor threshing and separation technology almost 50 yearsago, in 1975. Over time, its design has evolved to ensure it meets similarly evolvingdemands for throughput, grain protection, grain retention and straw quality. In the newCR10 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 andseparated. Each rotor features 40 standard rasp bars, eight HX raspbars and 12 spikedraspbars. The HX units combine the height of spiked raspbars with the profile of thestandard units, with a greater sidewall angle helping accelerate crop flow in the transitionzone 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 cropejection should the rotors need to be reversed. New rotor cages feature a stepped designwith a broader cage and higher vanes in the separation area, to allow greater crop matmovement, improved separation and enhanced power efficiency. The concave areacomprises two sets of three lightweight threshing concaves and separation grates, andtwo sets of six lightweight grates.
All-new TwinClean cleaning shoe
The new TwinClean cleaning shoe incorporates multiple features to boost throughputand minimize grain loss. It consists of two sieve systems in sequence, each having itsown upper and lower sieve and clean grain auger, and is based around a large grainpanwith an increased fallstep to the first upper sieve. Airflow is provided by a high-powercleaning shoe fan. Two automatic cross distribution mechanisms, one on the grainpanand 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 materialdistribution between left and right. A side-shake mechanism adds a lateral componentto the grainpan and sieve movement which evens out the material over the cleaningshoe’s full width. As such, the cleaning shoe can compensate for uneven feeding andside 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 theCR10 tank holds 16,000 litres and has a 159 l/sec unloading rate. Cross-auger shut-offallows 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 disengagingthe front cross auger, aiding topping-off of trailers. All unloading augers feature apivoting 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 ora high hood-mounted fine-chop unit. While the first of these is intended for dryconditions, the high hood-mounted unit is targeted at users needing to process highstraw 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 with52 counter knives working at 3,000rpm for chopping, or at 800rpm for straw swathlaying. Manual adjustment of the counter knives is standard, and remote hydraulicadjustment optional. A driven roller assists straw ejection when swathing, or into thespreader impellers when chopping. The two hydraulically-driven 800mm impellers, eachequipped with three paddles, spread chopped material at widths up to 15m (50ft). Anoscillating deflector behind the spreaders creates a dynamic pulsating effect on theresidue 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 andtwo rows of blades, plus a non-perforated beater pan. This is followed by a six-rowchopper 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 whenservicing is required. Remote chopper speed selection is optional. The pair ofhydraulically-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, anoscillating deflector is again fitted behind the spreaders on the high hood chopper, todynamically pulse the residue across the full cutting width. The IntelliSpread option usesradars to continuously assess the full width of the residue spread and automaticallyadjust left and right spreader speed to guarantee full width spreading. Further optionsinclude remote selection of chopper door position, chopper gears and counterknives.Also optional is a chopper load indicator, which provides information on chopper powerconsumption, allowing chopper power efficiency to be assessed in relation to chop lengthso the operator can select the optimal balance between power consumption, choppingquality 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 handwashtank with integrated soap dispenser located by its access steps, features multipleupgrades. Operation is made easier through incorporation of twin Intelliview 12touchscreen terminals. With the primary monitor on the right-hand console providingmanagement and monitoring of the combine’s key controls, the secondary monitor onthe A-pillar is configured for mapping and guidance. Both combines are equipped withthree cameras, providing views to the rear, of the grain tank and of the unloading augerspout, while a 360° bird’s eye view camera is optional, as is a trailer hitch camera. Eithermonitor can be configured to display external camera views. The operator can now alsofully control more functions remotely from the cab, including the speed of the rotors,chopper and unloading auger, reversing of the DFR and rotors, and fullengagement/disengagement of the straw chopper.
Elsewhere in the revised cab, changes include new-style brake pedals and foot pegs, aluxury steering wheel and premium cloth or leather seats, plus new multizone climatecontrol with floor level air ducts. A new Bluetooth radio allows operation of the radio anda mobile phone via the radio control panel in the roof liner, or one of the IntelliView 12touchscreens. Externally, new mirrors provide a wider view angle, with the right-handunit optionally electrically foldable, while windscreen access steps aid glass cleaning.
A comprehensive lighting package includes four LED beacons (two at the front and twostrips at the rear), 13 cab-mounted LED worklights, two stubble LED lights, oneunloading auger LED light, one graintank LED light, eight rear LED worklights, two LEDsidelights, three undershield LED strips, two engine service LED strips and an LED sievestrip. Optional ‘far distance’ lights of 36,000 lumens with 500m reach can be integratedunder 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 packagesdesigned to match the needs of the largest farms. A Core PLM Intelligence packagecovers the most commonly-specified requirements, such as IntelliSense, whereautomatic adjustments occur according to the harvest strategy chosen by theoperator, whether limited loss, best grain quality, maximum capacity, or fixedthroughput. The second option is an Advanced PLM Intelligence bundle, aimed atthose with the most advanced demands.
Correction signal packages for IntelliSteer automated steering and other functions suchas yield and moisture mapping are available from the factory in two accuracy levels withthree delivery options.
Via the optional IntelliField software, at no cost owners and operators are instantlyprovided with in-field data and can share boundaries, guidance lines and coverage datawhere 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 semiautomaticdiff lock which is engaged manually and disengaged automatically dependingon steering angle and forward speed. Models specified with SmartTrax are available withthree track belt width options of 660mm/26in, 810mm/32in and 910mm/36in, withrubber or hydraulic cushioning. Respective overall machine widths are 3.49m, 3.79mand 3.99m. For certain markets a wide beam configuration is available in combinationwith 910mm/36in tracks, with an overall machine width of 4.8m
Where a wheeled machine is preferred, New Holland and Michelin have co-developed900mm-wide tyres of 2.32m diameter (VF 900/65 R46), to minimise compaction andmaximise traction. Alternatives tyre options are VF 800/70 R46 (2.32m diameter) andVF900/60 R38 (2.05m diameter). Rear tyres on both wheeled and tracked combines areavailable in widths from 500 to 750mm. Other options include 710/70 R42 or 800/70R38 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 fedby a 1,300-litre fuel tank, while the powerplant in the CR11 is the 15.9-litre FPT Cursor16, also a six-cylinder turbocharged unit, with a 1,500-litre fuel capacity. Respectivemaximum power outputs are 635hp and 775hp. A new design layout sees the enginesinstalled longitudinally in the same direction and at the same angle as the rotors, formaximum efficiency, with cooling air being drawn from behind the grain tank. The CR10features two cooling fans, with three on the CR11. All exhaust manifold/turbo/aftertreatment installation is full isolated to reduce surface temperature of hot components.Harvesting engine speed is 1,900rpm, resulting in subdued noise and minimized fuelconsumption. In road mode, engine speed is 1,300rpm, for maximum travel speed withminimum 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 easyaccessibility, while the air filter is located conveniently at the left side of the combineframe, and can be removed from the ground without climbing to the engine deck.
An optional engine air compressor comprises an engine-mounted single cylindercompressor 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 accessoriesinclude brushes installed on each rotary dust screen, providing continuous cleaning inheavy dusts produced by crops such as maize/corn and sunflowers.
On the all-new hydraulic system on CR10 and CR11 combines, hydraulic hose routinghas been redesigned in dedicated routing highways to improve access and simplicity. Allharvest hydraulic drives are disengaged mechanically via a clutch in the main enginegearbox at start-up or during road travel, reducing drag and saving up to 20hp/15kW ofpower. The use of load-sensing pumps further reduces hydraulic power demands andimproves efficiency. Oil filtration has also been enhanced throughout the hydraulicsystem for increased reliability and reduced maintenance.
