The latest round of emissions regulations does not just affect tractors but also other engine-powered agricultural equipment and machinery, combines included.
For many manufacturers, having to meet these regulations is an opportunity to update or upgrade existing tractors or harvesters.
New Holland has extensively updated its emissions-affected tractor ranges and now is the turn of its combine harvesters.
New are the CX5000 and CX6000 series conventional straw walker combines from New Holland.
The firm has tailored the new series towards farmers and contractors harvesting around 500 to 1,500ac.
The entire range has been engineered to offer ultimate flexibility in all crops -- from grain through to maize and even specialist crops such as rice -- while guarantying optimal grain and straw quality.
New Holland's numbering strategy follows a common sense approach that was adopted on their 'emissionised' tractor series.
The CX stands for conventional, straw walker combine, while the five or six at the start of the series number means it is a five- or six-walker machine. There are just two models in each series, four new models in total, the CX5080, CX5090, CX6080 and CX6090.
Grain tank capacity is 7,000l on the smallest model, 8,000l on the two intermediate models and 9,000l on the largest model.
The maximum header width available on all models is 24ft.
The high positioning of the 100l/min over-the-top unloading auger helps cope with higher trailers, while the opening and closing of the grain tank covers can be electronically activated from the cab.
Power for the new models is provided by New Holland's sister company Fiat Powertrain (FPT) and all meet the latest round of emissions regulations, Tier 4A.
The smallest model in the series, the CX5080, develops 258hp, while the CX5090 and CX6080 develop 300hp.
All three models use a 6.7l Common Rail Nef engine while the range-topping CX6090 uses the Cursor 9 power plant and develops 333hp. All the engines employed in the new series use Selective Catalytic Reduction (SCR), or ECOBlue, as New Holland like to badge it. This, of course, requires AdBlue liquid to be carried, as it is necessary for injection into the exhaust's after-treatment system to neutralise harmful pollutants, turning them into water and nitrogen.
The combines carry a 110l AdBlue tank, which the firm says only needs to be filled at every other diesel refill.
The AdBlue tank is located next to the 580l diesel tank and both levels are displayed in the cab.
New Holland is helping its customers to ease into ECOBlue SCR technology by delivering a 1,000l AdBlue tank together with an electrical pump free of charge.
Body or panel styling on both the CX5000 and CX6000 has been modelled on the flagship New Holland CX8000 and CR9000 Elevation ranges. Large, single-piece opening side doors facilitate daily checks and maintenance. The range's curved shielding is a key New Holland trademark, as are the turntable stairs up to the cab instead of the fold-up design. The cab used on both series features a completely new interior. The seat's armrest has been redesigned to fit the range's reduced dimensions and the control layout, or 'operation logic', is similar to the flagship Elevation machines.
The most frequently used controls are grouped together to the right of the operator with the multifunction handle featuring all header, unloading and forward speed controls.
Similar to their tractors, the armrest mounted, IntelliView III colour touch-screen monitor displays information on all machine operating parameters.
This includes real-time moisture sensing, which New Holland says provides operators with an accurate moisture reading which is displayed on the IntelliView III monitor.
A sensor sits in the grain elevator and continually measures the moisture content, which enables the operator to fine tune machine settings in order to maintain grain quality. To ensure maximum header fill, New Holland's SmartSteer system employs laser guidance to automatically adjust the steering and ensure maximum header fill.
Their on-the-go yield sensor maps the yield of the different areas of a field.
This information can then be downloaded to be used in New Holland's precision farming software to generate field maps and aid crop management.
New Holland also uses what it calls a four-drum threshing solution. In addition to the standard threshing drum and beater, the firm uses a rotary separator which is says is ideal for harvesting in difficult conditions and in crops of a higher moisture content.
After all of these, their Straw Flow Beater accelerates the crop onto the straw walkers, aiding straw flow final separation.
For those harvesting a wider variety of crops that necessitate a concave change, New Holland has developed sectional concaves that it claims can be changed in 20 minutes by one man.
The firm's Opti-Thresh system facilitates improved grain sample or straw quality, the firm says, depending on what is required, by moving the position of a defecator plate in the combine. The firm's Multi-Thresh system alters the aggressiveness of the rotary separator to suit the crop variety or moisture.
For example, in wetter conditions it is operated on an aggressive setting to aid removing all the grain.
The adjustment is set less aggressively in dry straw conditions to retain quality.
Coping with undulating or hilly ground are New Holland's SmartSieve and Opti-Fan systems. The SmartSieve system automatically changes the throw angle of the grain on the sieve to prevent build-ups of grain and straw, which are a key cause of poor grain samples or grain losses.
The Opti-Fan system automatically adjusts the cleaning fan speed for travelling up or down hill, reducing the fan speed on upward slopes and increasing it on the downhill trek.
For more extreme gradients, the Laterale option is available on the CX5090 and CX6090 models and offers side-to-side levelling on gradients of up to 18pc. Also optional is a powered rear axle.
The CX series will not be available here until 2012. Prices for the CX5000 with a 17 foot header start at €201,000, while the CX6000 with a 20 foot header starts at €230,000.
