New Holland Agriculture has launched the CH7.70 combine that introduces a brand-new, Crossover Harvesting concept bringing together outstanding Twin-Rotor separation technology with the brand’s proven and renowned conventional threshing technology.
The new Crossover combine sets a new benchmark in capacity for mid-range combines, delivering outstanding grain and straw quality, and is equally at home in all crops and conditions. The highly fuel-efficient engine with patented HI-eSCR 2 technology for Stage V emissions compliance, delivers high productivity with extremely low operating costs. This performance comes with the superior comfort of the Harvest Suite Deluxe cab.
New Holland’s Lars Skjoldager Sørensen said the company designed the CH7.70 for professional arable farmers and contractors looking for a combine that delivers consistent, high performance in all conditions together with low cost of ownership.
“The new CH7.70 combine brings to our customers all the benefits of 45 years of Twin Rotor separation excellence combined with our best threshing technology – best-in-class productivity, top grain and straw quality, crop-to-crop versatility and reliability with low operating costs,” he added. “This unique concept heralds the new era of Crossover Harvesting by New Holland.”
According to New Holland’s Lionel Gleyroux, the new Crossover combine created a new segment in the brand’s wide offering, between mid-range conventional and flagship rotary models, further extending the choice of solutions for customers.
“It’s capable of meeting the specific needs of all types of farming operations,” he said. “The new Crossover Harvesting concept takes the best of our harvesting expertise to create the opportunity for every farmer and contractor to be more productive, versatile and effective. It offers the best of both worlds – New Holland’s best Twin Rotor and conventional technologies – to deliver segment-leading throughput.
“With the new Crossover Harvesting concept, our customers just get more: more productivity, more quality, more savings. The new CH combines proudly bear the Crossover Harvesting logo on their livery to signal the revolution they introduce under the hood.”
The new Crossover technology delivers up to 25 per cent higher throughput than a conventional combine in this segment. The two-drum threshing system features a 600mm diameter drum – the largest in the segment – with reinforced, heavy-duty design to deliver outstanding threshing performance. The large drum, combined with the user-friendly sectional concave, offers the best match in terms of versatility, enabling fast adaptation to different crops in less than 20 minutes.
The drum speed is controlled from the cab by a new heavy-duty hydraulic drum variator, so that the operator can easily ensure the speed is perfectly matched to the crop and field conditions. The threshing system is combined with proven New Holland Opti-Thresh system, which adapts to crop conditions and maturity simply by repositioning the rear part of the concave – no tools are needed. When the hinged top section is moved away from the drum, the rubbing action is gentler, improving straw quality.
The CH7.70 combines this high-capacity two-drum system with New Holland’s proven Twin Rotor concept to deliver the Crossover Harvesting concept. More than 45 years since it was first introduced, it delivers the most efficient and gentle threshing system on the market while reducing broken grains. The specially designed 21-inch, 3.45m long Twin Rotor system provides the largest separation area in the segment, at some 2.9 square metres, and is a perfect match to the CH7.70’s mission. The system requires minimal changes to the settings when switching between crops, resulting in outstanding crop-to-crop versatility.
The CH7.70 can be equipped with a range of Varifeed headers of up to 9.15m, including a brand-new 8.53m Varifeed version specifically developed for this range. The front face of the feeder housing can be mechanically adjusted to ensure perfect alignment with the header, thereby optimising the angle for each different header to deliver smoother, laminar crop flow for increased throughput and ensure the best flow whatever the crop.
The cleaning capacity of the CH7.70 is perfectly matched to its high threshing and separation throughput. It features the unique New Holland Triple-Clean cascaded cleaning system, which boosts cleaning capacity by up to 15 per cent with the addition of an extra cascade in the centre of the grain pan. The double flight cross auger, which transfers grain to the elevator faster, can result in an increase in throughput, improving capacity further.
The CH7.70 also delivers a flawless performance on slopes thanks to the proven SmartSieve system, that automatically compensates for side slopes up to 25 per cent, maintaining perfect sieve balance for uniform cleaning. The system also calibrates sieve action based on fan speed and kernel size to determine the optimal throwing angle. In addition, the award-winning Opti-Fan system automatically compensates for fluctuating grain speed across the cleaning shoe when the machine is working on slopes. It reduces fan speed when travelling uphill so no grain is lost out the back of the combine, and increases it when moving downhill to prevent clogging of the shoe.
For sustained performance in hilly conditions, a Laterale version, which uses a robust automatic levelling system, provides transversal slope correction of up to 18 per cent on both sides. The Laterale system is in addition to the standard Triple-Clean and self-levelling SmartSieve systems with the result of optimised cleaning efficiency over difficult terrain.
The CH7.70 features the proven Cursor 9 engine that develops 374hp – 34hp more than the CX6.90 – to deliver a consistently powerful and fuel-efficient performance in all conditions. It complies with Stage V emissions standards with the patented HI-eSCR 2 technology developed by FPT Industrial. The CH combine has been designed to deliver easy maintenance: only four greasing points make daily maintenance even quicker and the large service door on top of the straw hood door provides easy access. This maintenance-free after-treatment system, together with the exceptionally low fuel consumption, results in extremely low operating costs.
In addition, the standard three-year extended warranty (1,200 engine hours) covering the engine, driveline and after-treatment system, together with the long, 600-hour service intervals, further contributes to the combine’s low operating costs. This testifies to New Holland’s confidence in the superior quality of its flagship combines and its commitment to meeting its customers’ demand for a clear total cost of ownership for its equipment.
