CLAAS is rounding out the rest of their “700 Series” combine line at the Farm Progress Show with the now familiar updated design and enhanced features.
The LEXION line is now available with the following models:
- LEXION 780/780TT (Class 10) – replaces the LEXION 770 as the company’s highest capacity model
- LEXION 760/760TT (Class 9) – delivers throughput to spare
- LEXION 750/750TT (Class 8) – includes a high-speed (25 mph) TERRA TRAC option
- LEXION 740/740TT (Class 7) – includes a high-speed (25 mph) TERRA TRAC option
- LEXION 730P (Class 7) – a new “performance” addition to the LEXION line.
- LEXION 730 (Class 6) – a few less horses that the 730P
- LEXION 670/670TT (Class 7) – the straw walker LEXION combine, now with a TERRA TRAC option
All of the new LEXION combines get a bump in horsepower, while delivering greater fuel efficiency and fewer emissions. The new series offers a horsepower range of 320 to 543 HP at 1,900 rpm.
In addition to their Tier 4 engine enhancements, the new LEXION 700 series features an all-new DYNAMIC COOLING system. This variable speed, horizontally mounted cooling system draws clean cool air from above the combine, pulling it through the engine coolers and out all-new exhaust vents . . . creating a curtain effect that prevents dust from recirculating. The new, more efficient, cooling system draws less horsepower than its predecessor, allowing more horsepower to be used to maximize header, threshing and separation performance.
The LEXION 730-750 models come equipped with an all new center link suspension that helps transfer the weight of the combine better. Suspension and stability were also enhanced with a 4-link rear axle in the company’s largest LEXION 780 and 760 models. The patented CLAAS design allows for increased mobility with tires up to 67.3 inches high. The 4-link axle also features lateral movement and allows for more flexibility and a smaller turning radius.
“The design is unique to CLAAS and an industry exclusive. It not only enables the rear axle to pivot, but also gives a swing motion for enhanced turning capability and efficiency ... You get more oscillation and a tighter, more efficient turning radius,” Gray said.
An optional, all-wheel drive POWER TRAC is available in the new series with 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.
CLAAS Electronic Machine Optimization System (CEMOS) technology, is another option available on the latest LEXION combines. In corn and soybeans, a dialog-based version of the CEMOS system helps the operator make the correct combine settings for optimal speed and grain retention. In small grains, CEMOS AUTOMATIC continually adjusts the settings based on the operator’s chosen parameters as harvest conditions change with weather and yields.
A new header drive also provides for improved fuel conservation and performance on larger heads. The drive is capable of a constant output of 107 horsepower, with options of up to 268 horsepower. Maximum power can be reached and the right drive can be attained for every application.
What hasn’t changed is the CLAAS-patented Accelerated Pre-Separation (APS) system, which is the heart of all LEXION combines. The system consists of 3 cylinders; the APS cylinder, the main threshing cylinder and the impeller cylinder. The exclusive APS cylinder pre-separates up to 30% of the grain before it is fed into the dual rotors of the ROTO PLUS separation system found in all LEXION 700 series combines – or straw walkers, in the case of the LEXION 670.
A 29.2 foot auger adds to the unloading capacity of the new LEXION combines. This option is capable of an unloading rate of up to 3.8 bushels per second. Coupled with the new auger is the PROFI CAM camera system, which is positioned to monitor the unloading process and residue management system performance.
For operator comfort, an all-new leather operator’s seat comes standard with heating and ventilation controls.
