CLAAS’ LEXION 8000 and 7000 combine harvesters completely redesigned to deliver higher level of productivity, the company said
Already renowned for its efficiency and excellence in harvesting performance, CLAAS’s LEXION combines are set to raise the bar even higher with the 8000/7000 series, the German manufacturer claimed.
The new line-up, ranging from 461hp to 653hp in power, is set to make its Australian debut at the Henty Machinery Field Days this year.
CLAAS said the new series has been completely redesigned from the ground up, hence delivering 10 per cent more capacity than the existing 700 range.
“This is not a new series – it’s effectively a new machine,” said CLAAS Harvest Centre LEXION Product Manager, Steve Reeves.“Every aspect has been re-engineered to meet the needs of today’s grain producers – increased efficiency and ease of operation and reduced downtime and operating costs.”
The secret sauce of the combine harvester is its HYBRID threshing and separation system first launched in 1995 after more than a decade in development.
The accelerated pre-separation system smoothly accelerates crop flow to 20m/sec across all concave areas, meaning 70 per cent of separation occurs before the crop even reaches the twin longitudinal rotors, CLAAS said.
“At the time, the HYBRID system was rightly recognised as a breakthrough in harvesting technology,” Reeves said.
“It allows LEXION to operate more efficiently and longer in all harvesting conditions and crop types.
“CLAAS is still the only manufacturer to offer both systems in the one machine.”The new iteration of the system, the APS SYNFLOW HYBRID available in the new LEXION 8000/7000 series, takes the technology to a whole new level, CLAAS said.
“CLAAS has increased the diameter of the threshing drum by 26 per cent to 755 mm and the feed drum by 57 per cent to 600mm,” according to Reeves.
“Likewise, the capacity of the residual grain separation has increased by 20 per cent.
“Combined, these improvements optimise crop flow and separation efficiency whilst reducing power requirement.”
The system has undergone more than 6000 hours of field testing in 10 countries, including Australia, over the past eight years.
CLAAS has also increased the grain holding and unloading capacity on the LEXION 8000/7000 series to a maximum of 18 tonnes and 180l/sec respectively.
The first three models in the series – the 7600, 7700 and 8700 – are fitted with the 12.5-litre six-cylinder Perkins 2206D engine, which delivers a maximum power of 461, 524 and 571hp respectively.
The range-topping 8800 model is equipped with a 15.6-litre six-cylinder Mercedes-Benz OM 473 LA engine delivering 653hp.
All engines are equipped with DYNAMIC COOLING and DYNAMIC POWER.
“DYNAMIC COOLING is an on-demand variable drive cooling system that reduces power requirement by 26hp,” Reeves said.
“The horizontal cooling system creates a ‘curtain’ that prevents dust from rising.
“By comparison, DYNAMIC POWER is an advanced engine management system that automatically adjusts power output to field conditions for maximum fuel efficiency.
“This system has been proven to deliver fuel savings of up to 10 per cent.”
LEXION 8000/7000 can be equipped with the 635, 735 and 890mm TERRA TRAC tracked assemblies or wide diameter tyres (2.15m front and 1.75m rear).
CLAAS said both variants are capable of 40 km/h ground speed.
On-board technology includes CLAAS’ award-winning CEMOS AUTO machine optimisation system, which continuously reviews and automatically adjusts the threshing, cleaning and separation settings for maximum throughput, grain quality and fuel efficiency.
“These systems are not technology for technology’s sake – they are designed to make the operator’s job as easy and as comfortable as possible,” Reeves said.
“CEMOS AUTO can improve output by up to 20 per cent compared to the manual operation.”
The new CLAAS LEXION 8000/7000 combines feature CLAAS’ TELEMATICS as standard.
“This GPS tracking and data transmission system can be used for a range of jobs, including machine optimisation, harvesting logistics, fleet management, remote diagnostics and documentation,” Reeves said.
“For example, your service team can access your machine’s data to enable remote diagnosis and service scheduling.”
All models are fitted with JETSTREAM, which is an eight or six-stage turbine system that delivers a strong and consistent air blast over dual-ventilated steps for pre-cleaning the full length of the sieve box.
Optional 3D or 4D cleaning systems automatically adjusts the blower speed according to the lateral and longitudinal angle of the machine.
CLAAS LEXION 8000/7000 models can be equipped with either the new CLAAS CONVIO draper front or the VARIO variable cutterbar, which are both available in 13.8, 12.3 and 10.8m operating widths.
“CONVIO fronts ensure smooth, reliable crop flow with minimal grain loss, even in lighter conditions or direct-cut canola,” Reeves said.
“The optional FLEX configuration enables the cutterbar to flex up to 90mm upwards or 135mm downwards, making it ideal for harvesting pulse crops or lodged cereals.”
CLAAS VARIO variable cutterbars provide optimum performance in all crops and harvesting conditions, he added.
“The knife position can be adjusted from -10cm to +60cm ‘on the go’ for optimum throughput, flexibility and ease of operation.”
