The new additions include the new TC5000 five straw walker combine and the latest generation CX7000 and CX8000 Elevation conventional five and six walker machines.
“Conventional straw walker combines still account for 55% of combine harvesters in sold northern Europe,” said New Holland combine specialist, Nigel Honeyman.
New Holland has focused its attention on this market with the introduction of two new conventional combine series, “one conventional and one super conventional,” as Nigel described it.
New Holland boosts separation in new generation CX combines
The latest generation CX7000 and CX8000 Elevation super conventional combines deliver increased separation, cleaning and unloading capacity, according to New Holland’s combine specialist Nigel Honeyman.
There are also more tyre and track options while the operator benefits from improved ergonomics and comfort. At the rear, there are some changes to the chopper mechanism plus some clever developments in straw walker drive.
The new CX8090 is what New Holland described as the world’s most powerful straw walker machine producing up to 490hp. To help achieve an increase in capacity, New Holland’s Opti-Fan system is standard on all CX models which compensates for the effect of uphill and downhill slopes on harvesting performance.
The Opti-Clean system is standard on machines specified with a self-levelling cleaning shoe, and improves cleaning performance by up to 20% according to New Holland. The grain pan and shoe have been separated on the new CX machines and operate independently of each other.
According to Nigel, this optimises the stroke and throwing angles in the cleaning system with the grain pan, pre and top sieves operating independently to optimise material flow and increase the harvester capacity. The longer sieve stroke and steep throwing angle keep material airborne for better separation of grain and chaff.

A clever new feature on the CX7000 and CX8000 Elevation is the firm’s Opti-Speed straw walker technology.
New Holland has found that by varying the speed of the straw walkers, you can improve the overall combine harvester capacity by up to 10% when working on hilly terrain.
This system automatically varies the straw walker speed based on the field’s gradient. The operator selects walker speed from four pre-sets: wheat, maize, rapeseed and rice, and the Opti-Speed system takes care of the rest.
When driving uphill, the straw walker speed reduces to decrease the transport speed of the straw over the straw walkers. When driving downhill, the straw walker speed is increased to prevent blockages.
All grain tank sizes have been increased; and the CX8080 and CX8090 Elevation now benefit from a maximum 11,500-litre tank. Unloading speed tops 125 litres per second, 14% faster than the previous series, to empty the tank in just over 90 seconds. The firm is using chaff spreaders on the CX series as part of its residue management system.

Making the Opti-Fan system is standard on all CX models, allowing the use of bigger wheels and tyres for better flotation. The removal of the mechanical fan drive at the front right of the combine harvester allows scope to fit larger wheels and tracks.
The New Holland designed SmartTrax rubber track system is available on the CX7090, CX8080 and CX8090 Elevations models. New Holland claims that the triangle track structure reduces ground pressure by up to 57%, when compared with wheeled machines.
The SmartTrax features positive lug drive to transfer maximum tractive force to the ground. It is available in two track widths: 610mm (24-inch), for conformity with the 3.5m transport width restriction, and 760mm (30-inch) for those working in the most extreme conditions.
Two additional HID lamps to light the full header are on the options list and an extra lamp illuminates the field ahead.
The prices for the CX7080 starts at €241,200, while the top of the range CX8090 tracked unit retails for €364,450, both plus VAT.
Economy and cab improvements in TC5000s
Built in both Poland and Brazil, the smaller of the re-vamped New Holland TC5000 series combines have been around since the early 1990s.
For the new models, the cab is claimed to be 27% larger and with a 23% increased glazed area for better visibility and the noise level drops to 74dBA. With cab and seat suspension, the operator’s environment in the cab gets a makeover as well with the new ‘Harvest Suite’, which the firm said provides more space for the operator.
The new cab also incorporates a new right-hand control panel, InfoView II Monitor pillar panel and CommandGrip proportional multi-functional handle. This handle should be familiar to users of the T6, T7, T8 and T9 tractor ranges. In the combine, it manages all header and unloading operations.
There are three revamped models in the TC range, the TC5060, TC5070 and TC5080 which develop between 175hp and 258hp. The TC5070 and TC5080 are also equipped with ECOBlue SCR technology (AdBlue) engines for Tier 4A compliance, which according to New Holland reduces fuel consumption by up to 10%.
The engine power for the smaller, four-walker TC5040 and TC5050 remains unchanged.
Optional on the TC series are the Opti-Fan and SmartSieve systems. The optional Opti-Fan system, also found on the firm’s larger CX and CR ranges. This system claims to compensate for harvesting up and down slopes by automatically slowing the cleaning fan uphill and speed it up with the combine facing downhill. This is claimed to provide the air speed to minimise grain losses harvesting uphill, while not overloading the grain shoe and return system harvesting downhill.
New Holland claimed that the optional SmartSieve technology is ideal for operations which work on uneven ground. This system automatically changes the throw angle of the grain on the sieve, and can compensate for side slopes of up to 25%, by preventing build-up of grain and straw.
New Holland claimed that this increases cleaning capacity by up to 30% when working in heavy load conditions.
Header options include the firm’s heavy duty Varifeed headers with working widths of 4.87m to 6.03m. The Varifeed headers feature an adjustable knife floor, which can move the knife in and out by up to 575mm to compensate for different length crops.
AutoFloat II technology automatically adjusts header height to follow ground contours, which claims to prevent bulldozing when travelling uphill and to maintain uniform stubble height when travelling downhill.
The grain tank size has been increased to 6,400 litres on the TC5070 and TC5080 models.
New Holland quoted a grain tank auger unloading speed of 72 litres/second, and claimed full tank unloading in less than 90 seconds.
An optional moisture sensing system is available and the new TC5000 is pre-wired to fit the Telematics Essential GPS system.
Prices for the TC range go from €145,690 for the TC5060 to €193,960 for the TC5080.
