At Ag Connect 2013, Claas introduces its Class 10 combine the Lexion 780 and the company kicks off its global centennial celebration.
The trademark of the Lexion 780 combine is a higher horsepower , Tier 4 interim compliant 16 Liter Mercedes-Benz engine that is cooled via the Dynamic Cooling system. The combine boasts 543 hp with a bulge that increases total power output to 590 hp. The new cooling system is placed horizontally behind the engine with a 63" rotating screen to draw in clean air from the top of the combine. A variable fan drive helps conserve power by adjusting speed automatically, depending on the level of cooling needed.
Suspension and stability are enhanced with a 4-link rear axle, which features lateral movement and allows for more flexibility and a smaller turning radius. The patented design allows for increased mobility with tires up to 67.3" high.
In line with the automation and ease of use of the Lexion 780, the all-wheel drive POWER TRAC is engaged by the press of a button. The powerful yet fuel efficient drive capitalizes on a second hydrostatic drive on the rear axle; additional traction can be employed and intelligent control technology can be engaged while on the move.
CEMOS (Claas Electronic Machine Optimization System) technology, a dialogue-based system that allows the operator to establish the correct situation settings, has become automated in the new Lexion 780 series. CEMOS has reached a second stage and is now self-setting for the various situations an operator may encounter. Claas has focused on telematics and using sensors and monitors to optimize performance in the field.
A new header drive also provides for improved fuel conservation. The drive is capable of a constant output of 107 hp, and a variable output of up to 268 hp.
Another Claas patent is the pre-accelerator in the APS threshing system.
The 4XL grain auger measures 29.2’ and is capable of an unload rate of up to 3.8 bu per second. The new PROFI Cam is positioned to monitor the unloading.
