Maximising output, minimising losses
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 20,000L grain tank and a 15.9L FPT Cursor 16 engine producing 775hp. The CR10 engine is a 12.9L FPT Cursor 13 generating 635hp, while its grain tank holds 16,000L. Beyond additional power and grain capacity, the key features, according to the company, that take these combines into a new league in terms of output, sample quality, and loss minimisation include longer twin rotors and the new Twin-Clean cleaning system.
More capacity
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 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 for the grain to 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.
All-new TwinClean cleaning shoe
The new TwinClean cleaning shoe incorporates multiple features to boost throughput and minimise 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 per cent. Overall size of the complete sieve area is 8.76m².
Grain tanks that maximise autonomy
The CR11 grain tank holds 20,000L with an unloading rate of 210L/sec, while the CR10 tank holds 16,000L and has a 159L/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 per cent 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.
Choppers
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 two rows 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.
Technology plus comfort
The CR10/CR11 cab, which sits beneath new roof styling and has a 25L 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. 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.
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 grain tank 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.
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).
