Claas Presents the novelties for the next campaign

Lexion 780, a new model for a harvest of height

Editorial Interempresas07/09/2012

To finals of August Claas gave to know his novelties for the next campaign. A retahíla of new models and systems that pretend to offer to the agriculturalist more efficiency and productivity in his daily activity. The 780, new model of the range of cosechadoras combined Lexion, heads the list of novelties, in which we also find the new models of the Tucano and Cemos Automatic, an only system for the optimisation of performance, quality, efficiency and hygiene in the harvest.

It was the Lexion 770, up to now the cosechadora more powerful of Claas, the one who established the current world-wide record of harvest of wheat in 8 hours in 2011 and the one who arrived to complete a proof of resistance of 20 hours of harvest followed. However, it will be a new Lexion, that will arrive to the market from the month of October, the one who will elevate even more the level of performance in the harvest. The cosechadora Lexion 780 surpasses the previous model no only by the incorporation of the new system Cemos Automatic, but also because they enter novelties and improvements after the renewal of the design of the series Lexion in his group.

The new range Lexion composes of four models of the series 700 and five models of the series 600, that cover a range of powers from 305 CV (Lexion 620) until 598 CV (Lexion 780), according to ECE R 120. Thanks to the new technology, all the models have a greater performance of engine and fulfil with the necessary phase IIIb (Tier 4i) of standard of broadcasts. The characteristics of the engine have optimised and has reduced the nominal speed of 1.900 rpm in all the models, what allows a lower consumption of fuel. The two more powerful models, the Lexion 780 and 770, are promoted by an engine Mercedes-Benz that uses the technology SCR (Selective Catalytic Reduction) and an additive of urea to reduce the broadcasts.

To accommodate the increase of power, Claas has developed a system of refrigeration totally renewed for the new range Lexion. The four new models of the series 700 use the system of 'dynamic cooling' –a new system of refrigeration with accionamiento of the ventilation variable–. The system works according to the principle of 'cooling under demand', that is to say, alone provides the power of refrigeration really needed by the machine. With this achieves a half saving of 15 kW. The rpm complete only reach in operations to full load.

The system of trite in the Lexion 780 also has been optimised. Whereas the current Lexion 770 has the characteristic system of 5 concave by rotor, the separation in the Lexion 780 llevar using 2 x 6 concave, with an increase of the speed of the rotor until the 1.250 rpm. Besides, all the models of the series 700 are instrumented with the tested system of cleaning Jet Stream. Another new characteristic is the blockade of the differential for the Lexion 780 and a new version on wheels of the 770. These two models are instrumented with a new axis of four articulations. It treats of a system developed and patented by Claas, that provides a greater stability and capacity of load in irregular terrains. The new axis of four articulations remains suspended in four points, providing, in addition to the vertical movement, also a lateral movement. Also it allows that it can instrument the machine with tyres bigger, with a diameter of until 1,65 m.

Tucano: More intelligence and performance

The Tucano has won in performance, confort and intelligence for the next season of harvest, and has been updated to include some of the characteristics tested in the Lexion. The models Tucano 470, 450, 440, 430 340, 330 and 320 are promoted by the last generation of motors Mercedes Benz, with greater ranks of power, of until 326 CV (ECE R120). The selective catalytic reduction (SCR) guarantees that the motors fulfil the regulations of broadcasts. The concept of refrigeration of the Tucano also has reviewed to provide the necessary capacity of refrigeration increased. In the models Tucano 470 to 340 has widened the radiador giratorio, expanding the surface of entrance of air in 33%. The resultant flow of increasing air improves the performance of refrigeration of the system until in 15%.

The Tucano has won in confort additional, especially in the area of operation from the seat of the driver. The empuñadura CMotion multifunción has remained integrated cheese cheese in the apoyabrazos of the right, being developed especially to ensure the ergonomic efficiency for the right hand and handles with the concept of three fingers. The complete series has adopted the operating system Cebis of the Lexion –a variant simplified with key of fast access and the switch giratorio Cebis– that uses to control adjust them basic of the machine in the way of work. In the terrain of the intelligence, the Tucano also has learnt of his greater sister, and now works exactly of the same way that the Lexion: with telematic, cartography in field, and with GPS Pilot and Laser Pilot in both sides of the bar of cutting.

Cemos Automatic: The increase of performance in the harvest can be simple

With his new series Lexion 700, Claas presented the first model of cosechadoras that adjusted automatically to the conditions of harvest. In 2010, Claas presented Cemos (Electronic System of Optimisation) for his cosechadoras Lexion. This system of assistance to the operator helps to improve the performance of harvest, guiding to the operator in an optimum configuration of the machine through suggestions in adjust them. However, the operator will have to activate this option manually to accept or refuse the suggestions. The system is, therefore, a dialogue between the operator and the machine.

The system Cemos Automatic in the new Lexion promises to be a revolution in the harvest, like system of adjust entirely automatic for the process of separation and cleaning. In combination with the pilot GPS, system of automatic steering, and the regulator of discharge Cruise Pilot, the cosechadoras Claas can realise a harvest almost totally automatic, with an upper performance, greater quality and cleaning of the grain, a consumption of minimum fuel and ease in the operative.

The new system Cemos Automatic uses numerous sensors to monitor a wide quantity of the parameters of the cosechadora with total precision and immediately realise adjust them necessary to the conditions existent, dand a totally automatic form. Here does a distinction between two systems of work: Cemos Car Separation, that optimises the separation of the grain residual by means of the adjust of the parameters of speed of the rotor and the position of covers it of the rotor; and the Cemos Car Cleaning, that regulates the process of cleaning through the parameters of the speed of the fan, as well as the abertura upper and inferior of the sieve.
