Fuel efficiency, emissions controls and larger grain tank underline the list of quality components found in the new CLAAS LEXION 670 straw walker combine.
In compliance with the Tier 4i emissions standards, the LEXION 670 model comes complete with a Cat C 9.3L, 360 horsepower engine that is capable of reaching a 394 horsepower bulge. Based on CLAAS POWER SYSTEMS technology, the emissions-friendly engine aims to deliver optimal power transfer at an exceptionally low fuel consumption rate.
In order to maintain optimal engine temperatures — CLEAN SWEEP — a planar dust extraction system automatically sweeps and cleans the radiator. The extraction system also strives to reduce dirt accumulation on the cooling ribs.
A hallmark of CLAAS combines — capacity combined with efficiency — the LEXION 670 unit comes complete with a 300 bushel grain tank and optional 4XL unloading auger. The higher capacity tank is designed to incorporate greater productivity and versatility. Additionally, the unloading components are more efficient; a 29.2 foot auger satisfies a 3.3 bushel per second unloading rate.
The optional CLAAS C-MOTION JOYSTICK — recently selected as a recipient of an AE50 award from the American Society of Agricultural and Biological Engineers for advances in agricultural engineering — is designed to allow a three-finger operational style. The thumb, index and middle fingers are each incorporated to control separate aspects of the machine. An operator can use his or her thumb to control header height, reel height, auto-pilot and feederhouse/header stops. The index finger is used to control unloading tube swing-in and swing-out and engage/dis-engage, while the middle finger controls the rocker switch for manual header tilt control and cutter bar position.
Ease of operation was also taken into consideration during the development of the new combine line. Born of this focus was the optional CRUISE PILOT system; this component tracks speed, feederhouse crop volume, engine load and grain losses. Through the constant monitoring of these aspects, the CRUISE PILOT system can anticipate peak loads and maintain maximum productivity levels.
As with the previous line of LEXION 670 combines, the APS threshing system starts with a pre-accelerator that more thoroughly separates the harvested crop. Nearly 30 percent of all grain can be preseparated through the APS cylinder, thus reducing the load on the main concave. The enhanced threshing system applies higher centrifugal force, creating a net performance increase of nearly 20 percent without negatively impacting fuel consumption.
Ensuring quality and protecting against overloading are pinnacle components of the APS threshing system. A closed threshing drum facilitates crop flow and gentle handling within the combine. Parallel concave controls and dis-awning plates give the operator further control over threshing performance; the advanced control allows for protection from damaging objects during harvest.
