Harvesting Now - New Holland launch CR9090 Elevation - the highest capacity combine in the world 
  • 591 hp/435 kW turbo compound engine
  • New generation 35ft/10.7m  Varifeed™ header 
  • Adjustable rotor vanes for increased capacity
  • Opti-clean™ system with 6.5 m² cleaning area
  • Largest volume cab with latest IntelliView™ III monitor
  • 12,500 litres grain tank

New Holland’s latest rotary combine model, the CR9090 Elevation, has been developed with the most demanding arable farmers and contractors in mind. Claiming the title of the highest capacity combine in the world, the new CR9090 Elevation builds upon the proven qualities of the award-winning CR9000 range, whilst adding big features of its own including a new 35ft Varifeed™ header, market-leading power from the latest turbo compound engine, largest cleaning area and the biggest grain tank on the market. These enhancements result in the CR9090 Elevation offering a 10% increase in performance compared to the CR9080 Elevation, which is already a high capacity machine.

Greater power, performance and fuel efficiency
Using the same 13 litre Iveco Cursor engine with turbo compound technology that powers the latest forage harvester and the T9060 tractor, the CR9090 Elevation boasts 544hp/400kW at rated engine speed with a maximum harvest power of 591hp/435kW available, 61hp/45kW higher than the CR9080 Elevation. Turbo compound technology offers greater engine efficiency, with a 5% fuel saving when compared to a similar horsepower standard engine. When combined with the CR9090 Elevation’s larger 1160 litre fuel tank, it ensures the combine can work hard all day without stopping. The technology is fully compliant with 100% biodiesel usage, and with this alternative fuel becoming very competitively priced, this can result in significant savings for the owner.

The turbo compound system uses a second turbine, downstream of the first, to recover energy from the engine exhaust gases that would otherwise be lost or wasted. To match the cooling requirements of the engine, the CR9090 Elevation is fitted with 32% greater cooler capacity compared to the CR9080 Elevation, kept clean by new dual-rotary air screens.  Drivelines are also up-rated to handle the additional power and torque.

New 35ft/10.7m  Varifeed™ header
With the introduction of the CR9090 Elevation comes the new 35 ft/10.7m  Varifeed™ grain header designed for modern farming practises. A rugged frame construction features a high speed heavy-duty knife drive, large auger diameter and extended reel tine reach to ensure the header matches the high capacity of the new combine.

The 575 mm fore-aft knife position adjustment on the new Varifeed™ grain header can be controlled from the combine cab, and the long floor travel provides trouble-free field operation in a wide variety of crops and conditions.

Next generation rotary and cleaning technology
The CR9000 range uses the unique Twin Rotor™ system to efficiently thresh and separate the crop. By dividing the crop into halves, the Twin Rotor™ concept spreads the crop over the two rotor surfaces to create an enormous active working area. In addition, a higher maximum rotor speed allows even more crop to be processed. Repeated agitation of the crop by the segmented, staggered and spirally mounted rasp bars and separation slats creates a continuous threshing and separation, which offers high capacity and a gentle rubbing action that result in excellent grain and straw quality.

The CR9090 Elevation extends this concept with adjustable rotor vane covers that can be set in one of three positions by the operator to optimise separation performance for differing crops and conditions. An increased capacity and a high quality straw and grain sample are maintained as the processing velocity is matched to the ideal threshing and separation action.

The DLG (German Agricultural Society) awarded the New Holland CR9000 combine three medals. A gold medal for the combine’s Grain Cam™ system and two silver medals for the Opti-Clean™ cleaning shoe and IntelliCruise™ system recognised the technical innovation and the production benefits of new technologies, which all feature on the new CR9090 Elevation.

The Grain Cam™ system monitors the grain sample quality as it travels up the clean grain elevator. The sensor detects and calculates the amount of ‘material other than grain’ (MOG), which includes broken grains, using image processing software to analyse the sample displayed. The operator can adjust the cleaning shoe and threshing system to maintain or improve the grain sample, consistent with displayed information shown on the new IntelliView™ III monitor in the form of a graph.

To handle the increased power and capacity of the CR9000 Elevation combines, New Holland has developed a new self-levelling cleaning shoe. The latest Opti-Clean™ system features increased sieve throwing strokes and steeper throwing angles and the largest cleaning area on the market at 6.5 m². The grain pan, the pre-cleaner and top sieve have been decoupled from each other enabling the movement of each individual component to be optimised. The Opti-Clean™ shoe is the first to allow opposite movement of the grain pan and upper sieve, increasing the cascade height for greater separation capacity and more aggressive cleaning with a lower overall vibration level.

The IntelliCruise™ automatic crop feeding system monitors crop load on the header to ensure a smooth optimisation of the driving speed. A sensor monitors the crop load on the header and straw elevator driveline giving the earliest possible detection of variations in crop load. The combine’s forward speed is automatically adjusted based upon this information, resulting in consistent and optimum performance and maximum operator comfort.

With a grain tank capacity of 12,500 litres, the CR9090 Elevation holds close to 20% more than the CR9080 Elevation, yet when the grain tank covers are folded down, the combine is still within the four metre transport height limit.

The powerful new Opti-Spread™ system, mounted behind the straw chopper evenly distributes chopped straw across the full header width.  It meets a wide range of spreading width requirements and can be conveniently controlled from the cab. The optional spreader uses two rotors and adjustable deflectors to neutralise the effects of side winds or sloping ground.

For reduced soil damage and improved drive characteristics when working in difficult field conditions, the CR9090 Elevation can be equipped with rubber tracks, increasing the combine’s versatility and profitability. The Tidue triangular design enables the track to ride over wet areas, limiting ruts and soil damage with minimal scuffing effect when turning on headlands. 24”, 30” and 36” track widths are available and the simple bolt on design means the track system can be utilised across multiple applications.

Class-leading comfort and control
Operators of the CR9090 Elevation will immediately appreciate the working environment of the combine’s spacious cab. The 5.8 square metre glass area provides unobstructed views to the front of the combine, allowing the operator to clearly monitor crop and feeding conditions.

The new IntelliView™ III colour monitor has a wide easy-to-view screen providing details information and control of the combines systems while the touch-screen capability being makes it simple to navigate. For improved productivity, the new monitor also allows the DGPS-based IntelliSteer™ automatic guidance system to follow curved lines that were marked during the initial field pass or during a prior field operation.
