Right here is iVT’s full, in-depth case research of the biggest mix harvester on the planet – New Holland’s CR11 – together with an in depth have a look at the all-new expertise
New Holland first launched its model new, utterly redeveloped CR11 mix harvester to the general public eventually November’s Agritechnica, within the course of touchdown a Gold Award for Innovation. It’s most important promoting level to clients was that being boosted with leading edge expertise, the machine can harvest crops with better effectivity and productiveness, whereas decreasing grain loss and harvesting prices. It additionally occurs to be thought to be the world’s largest mix.
Taking the legacy of the corporate’s flagship CR line – notably topped by the CR10.90, world document holder for probably the most wheat harvested in eight hours – the brand new CR11 was designed, and is being produced, at New Holland’s Centre of Harvesting Excellence in Zedelgem, Belgium.
Highest productiveness available on the market
Subsequent yr marks the fiftieth anniversary of the New Holland Twin Rotor expertise, and the brand new CR11 highlights the benefit of the Twin Rotor idea that revolutionised mix harvesting. It’s because of the Twin Rotor expertise that the brand new CR can supply the best productiveness at lowest grain crackage available on the market.
“The CR11 is a totally new mix constructed utilizing over 8,000 newly developed components, which equates to over 90% of the components used,” says Geert Nerinckx, New Holland’s CR11 world product supervisor. “It is a larger mix and is far more productive than many available on the market. Its most important aim is to scale back the whole value of harvest for our clients.”
Trying intently on the machine, and beginning with productiveness, the feeder channel has been made wider to permit extra materials by means of. It has larger rotors which are 50% longer, and this permits the machine to feed immediately into the resident system.
Improved backside line
Extra productiveness, near zero grain losses, higher and extra environment friendly residue administration and a major discount in downtime are the 4 pillars the CR11 was constructed on – and with a better total goal to scale back the whole value of harvesting to enhance the farmer’s backside line profitability.
The CR11 is powered by a much bigger engine, the Cursor six-cylinder, 16 litre 775hp C16 engine by FPT Industrial. The mix’s grain tank capability has additionally been elevated
to twenty,000 litres.
“The grain obtain fee has been elevated to 210 litres per second which implies the larger grain tank may be emptied in lower than 100 seconds,” says Nerinckx.
Trade first
With a design aim of zero loss, the New Holland engineers developed the double cleansing shoe. The brand new Twin Clear cleansing shoe comes with two cleansing programs behind one another, with two higher sieves, two decrease sieves, two clear grain augers and two units of strain sensors to measure cleansing shoe load.
As an trade first, the brand new Twin Clear system is totally automated to ensure even cross distribution of the cleansing shoe, for optimum capability, however nonetheless with grain loss ranges near zero.
“When you’ve such excessive capability of grain, it must be cleaned effectively, whereas ensuring there is no such thing as a grain loss,” says Nerinckx. “We gave our engineers the duty of designing a cleansing shoe with zero grain loss and so they got here very near that aim.
“We name it Twin Clear, which implies it has two cleansing programs in a single cleansing shoe. There’s a wider and longer cleansing pan which is adopted by two cleansing programs, and is all totally automated. It’s all a part of the IntelliSense data system of the mix, and repeatedly measures cleansing shoe load, left, proper and after, utilizing sensors. If it detects any anomalies left or proper, it is going to right the distribution routinely.”
Assembly future calls for
New Holland says it has designed the brand new CR11 in anticipation of the way in which through which future harvesting calls for will proceed to evolve. It additionally factored in suggestions from clients looking for better capability, decrease grain losses and most safety of the grain high quality.
Recognising how greater yielding crops and unpredictable climate can have an effect on each one season’s crop and the subsequent, New Holland engineers aimed to design a machine that may play
its full half in delivering most productiveness, and clear fields rapidly to make sure high quality is protected and the next yr’s crop institution can happen in good time and in good circumstances.
“We’re working with 15m headers however have additionally examined 18m headers in Australia,” says Nerinckx. “Some contractors will want to unfold the residue materials over the total width of chopping, due to this fact we’ve got a totally new automated resident system to try this.”
The CR11 comes with Intellispread and two radars, one on the left and one on the suitable of the mix. Radar beams present the operator precisely the place the straw particles are touchdown within the subject, even by means of the mud clouds generated by the machine.”
“Its most important aim is to scale back the whole value of harvest for our clients”
Chop and unfold
The utterly new residue administration system includes a brand-new chopper and chaff spreader system, designed to make sure the perfect chop high quality and even residue spreading over as much as 60ft chopping width.
The Intellispread radar system, winner of a 2022 Agritechnica Innovation Silver Medal, automates the spreading management to make sure full and even residue protection behind the mix, no matter wind results, crop sort or moisture circumstances.
“On the driveline, the whole cropflow channel is wider, however the transport width continues to be the identical,” says Nerinckx. “We had been capable of obtain that by placing among the drives contained in the channel. For instance, we’re utilizing the left rotor for the driveshaft of the Dynamic Feed Roll. That’s implies that the whole DFR driveline goes away and you’ll widen the cropflow channel since you are driving the DFR together with your rotor.”
Diminished downtime
The engineers additionally got here up with a brand new automated unblocking process, designed to scale back machine downtime. Whereas the brand new CR11 mix is able to be pushed for optimum throughput, New Holland recognises that it’s unattainable to utterly remove any danger of plugging the machine with straw. Within the unlikely occasion of operator error inflicting a blockage within the mix, the automated system to unblock will kick in and information the operator by means of an unplugging process in a means that clears the mix in minutes slightly than hours, with out requiring the operator to exit the cab or carry out any bodily effort.
No concern of blocking
As a result of it considerably reduces downtime brought on by such a situation, the automated reverser helps and encourages the operator to use the mix’s full capability potential with out concern of blocking. As well as, this characteristic will increase security whereas clearing a blockage, as a result of no particular person is leaving the cab throughout the automated unplugging course of.
Fewer drive elements
Downtime prevention is additional aided by the mix’s revised driveline simplicity with as a lot as 25% fewer drive elements and with the elimination of all chain drives.
“One other good thing about this mix is that we now not have any drive chains, solely belts, shafts and CVT drives,” says Nerinckx. “With 25% fewer drives, the profit is the operator can unblock the mix from contained in the cab.
“Each mix driver who has blocked the machine and is aware of it could actually take hours to clear it out. With this method, if a blockage happens, the mix itself will seek for the blocked materials, clear the blockage, pull the fabric by means of, and inside 5 to 10 minutes regular harvest operations can proceed once more, with the operator by no means leaving the cab.”
Finest seat in the home
Contained in the cab of the CR11, New Holland has mounted the brand new Intelliview 12 show and IntelliSteer steering system, along with different important precision farming features corresponding to telematics and distant display screen viewing, for ease of use.
Additionally, NutriSense comes with a NIR sensor that screens crop high quality by way of the usage of close to infra-red mild to analyse vitamins like protein, starch and oil contents, plus moisture ranges, and may create maps of those for additional agronomic evaluation.
“The cab additionally comes with a bunch of upgrades,” says Nerinckx. “It has a putting new design, new seat and a model new console. A brand new console was mandatory as we’ve got 10 new controls, that had been guide exterior the cab, and at the moment are contained in the cab as distant controls. Distant controls offers consolation to the operator and likewise reduces the downtime of the machine, as there is no such thing as a must cease and go exterior to vary the guide controls. These distant controls within the cab may be automated.”
The fitting observe
Seen upgrades on the brand new CR11 mix embody the brand new 15m (50ft) draper header manufactured by MacDon for New Holland.
Recognising the developments for diminished floor compaction together with transport width rules, the CR11 gives a spread of wider tracks and greater tyres.
The machine at Agritechnica was fitted with tyres from Michelin, the Michelin Cerexbib 2, dimension 900/65R46 with a diameter of two.32m, that are the results of a co-development between New Holland and Michelin.
Subsequent-level tyre dimension
New Holland says that is the primary time that this subsequent degree of tyre dimension has been launched on a mix of any sort, and the longer tyre footprint and elevated traction present a diminished floor compaction with no precedents in harvesting.
Visually, the producer believes that shut collaboration between industrial design and engineering groups, along with product specialists and model advertising, created such a brand new, impressionable design that focuses on buyer wants in addition to aesthetic sensibilities.
The tip result’s an iconic, refreshed design that’s trendy but timeless. The move of the harvest is underlined on the outside panels by the dynamic blue characteristic that runs throughout the smooth physique by means of the assorted features.
