New Holland has launched a new mid-range combine: Dubbed the CH7.70, it features an innovative ‘Crossover Harvesting’ concept that the company claims brings together outstanding twin rotor separation technology with its proven and renowned conventional threshing technology to deliver substantial efficiency gains.
Meanwhile, a highly fuel-efficient engine with patented HI-eSCR 2 technology for Stage V compliance ensures high productivity with extremely low operating costs, while operators also benefit from the superior comfort of the company’s Harvest Suite Deluxe cab.
However, it is the efficiency gains offered by the new Crossover approach that are most likely to interest potential customers. According to the manufacturer, the technology can deliver up to 25% higher throughput than a conventional combine in the same 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.
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 suited to the crop and field conditions. The threshing system is combined with the manufacturer’s proven 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 what it describes as the Crossover Harvesting experience. The specially designed 21in, 3.45m-long Twin Rotor system provides the largest separation area in the segment, at some 2.9m², and 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 alignment with the header, thereby optimizing the angle for each different header to deliver smoother, laminar crop flow for increased throughput and ensure the best flow whatever the crop.
Best-in-class triple cascade cleaning
The CH7.70 features the patented New Holland Triple-Clean cascaded cleaning system, which boosts cleaning capacity by up to 15% 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 company claims.
The CH7.70 also delivers a flawless performance on slopes thanks to its proven SmartSieve system, which automatically compensates for side slopes up to 25%, 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% on both sides. The Laterale system is in addition to the standard Triple-Clean and self-levelling Smart Sieve systems with the result of optimised cleaning efficiency over difficult terrain.
Fuel efficiency and low cost of ownership
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 also 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, according to the company.
In addition, a standard three-year extended warranty (1,200 engine hours) covers the engine, driveline and after-treatment system, which together with long, 600-hour service intervals, further contributes to the combine’s low operating costs.
Lars Skjoldager Sørensen, crop harvesting product management global, commented: “We 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. This unique concept heralds the new era of Crossover Harvesting by New Holland.”
“The new Crossover combine creates a new segment in New Holland’s wide offering, between mid-range conventional and flagship rotary models, further extending the choice of solutions for our customers, capable of meeting the specific needs of all types of farming operations,” added Lionel Gleyroux, combines and New Holland flagship Europe. “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,” continued Gleyroux.
Carlo Lambro, New Holland brand president, concluded: “New Holland revolutionised the way farmers harvested over 45 years ago. Today, with the launch of the new CH Crossover Harvesting combine, it confirms its global harvesting leadership. Our brand offers a wide choice of technologies capable of meeting the specific requirements of every farming operation with solutions focused on innovation, sustainability, and outstanding cost efficiency.”
