Record setting New Holland CR9090 combine harvester to debut in Australia

Supplier News

New Holland  Dealer Principals gathered for a national conference in Sydney recently and viewed the launch of the biggest combine harvester to be released in Australia, the CR9090.

The CR9090 combine harvester currently holds the Guinness World Record for the most grain harvested, specifically 551.61 tonnes of wheat over an 8 hour period. The spot work rate was as high as 100 tonnes/hour while the average was 68.95 tonnes/hour.

The CR9090 combine harvester will feature greater power, performance & fuel efficiency using the same 13 litre Iveco Cursor engine with turbo compound technology that powers the latest T9060 tractor. The CR9090 Elevation boasts 544hp/400kW at rated engine speed with a maximum harvest power of 591hp/435kW available. 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 also fully compliant with 100% biodiesel usage.

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 cooling capacity compared to the CR9080, kept clean by new dual-rotary air screens. Drivelines are also up-rated to handle the additional power and torque.

The CR9000 combine harvester 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 a large 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 results in optimal grain and straw quality.

The CR9090 Elevation extends this concept with adjustable rotor vane covers that, when set in one of three positions by the operator, optimises 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.

Additionally the CR9090 will feature a new cleaning system that is designed to handle the increased power and capacity of these combine harvesters. 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 allows 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.

To make the operation of combine harvesters for extended periods easier, the CR9090 will also feature the IntelliCruise automatic crop feeding system which 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 harvester'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 will hold more grain than any previous New Holland CR9000 combine harvester. The CR9090 will feature fold down grain tank lids with a four metre transport height limit.

The 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.

The CR9090 Elevation features a spacious 5.8 square metre glass cab area, providing unobstructed views to the front of the combine. This allows the operator to clearly monitor crop and feeding conditions.

The new IntelliView III colour monitor has a wide easy-to-view screen providing detailed information and control of the combine harvesters systems while the touch-screen capability 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.
