The addition of the new Lexion 740 extends the availability of all the high-performance features of the Lexion Hybrid range in a new entry-level model. The previous smallest model in the Hybrid Lexion 700 range was the Lexion 750, which is powered by a 449hp engine. The new Lexion 740 features the same Stage IIIB compliant six-cylinder Caterpillar C9.3 Acert engine, but developing a maximum power output of 400hp at 1,700rpm.
As with the larger Lexion 750, the new 740 has a 1,420mm wide APS accelerator and closed threshing drum, feeding into the twin 4.2m long Roto Plus secondary separation system with Jet Stream cleaning and is suitable for use with cutterbars up to 9.0m wide.
As standard, the Lexion 740 features a 10,000 litre grain tank and is controlled using the latest C Motion multi-function joystick, with all the main operating settings monitored using the colour Cebis II terminal. As with the rest of the Lexion 700 Hybrid range, a wide range of options are available, including the advanced Cemos and Cemos Automatic combine performance optimisation system, which fully automates grain cleaning and separation.
Cemos Automatic monitors more than 50 different settings and can be used to continuously monitor and automatically adjust the combine threshing and separation settings for optimum grain quality and output.
A new development for 2014 is the option of a new Grain Quality Camera for the Lexion 780 and 770. Using a high-definition colour camera mounted in the top of the grain elevator, the images are processed using image evaluation software to highlight broken or non-grain constituents, which are then displayed either as a real-time image or bar diagram on the Cebis screen.
On combines fitted with Cemos Automatic, this information is also used to extend functionality and provide additional information to further enhance Cemos Automatic and enable the system to automatically monitor grain quality and further reduce losses.
A further new development available on all Lexion models fitted with a radial spreader is an Automatic Discharge Adjustment option. Sensors mounted on the rear light brackets are used to automatically monitor changes in the direction and strength of any crosswind, or variations in slope angle and then uses this information to automatically adjust the throw of the spreader. This ensures that an even distribution of straw is always maintained across the full cutting width and is one less thing for the operator to have to monitor and adjust.

| A Terra Trac version of the Lexion 750 will be available from 2014. |
Claas leads the way in the development and use of track systems for combines and, in the Lexion 760, is the only manufacturer to offer a combine with a 40km/hr road speed. For 2014, Claas will extend availability with the introduction of a new Terra Trac version of the Lexion 750. This brings to four the number of Lexion 700 Hybrid models for which Terra Tracs are available, plus there is also a Terra Trac version of the Lexion 670 straw-walker combine.
This new entry-level model uses the latest third-generation Terra Trac units. These feature independent hydro-pneumatic suspension on the drive wheel which automatically adjust to ground contours. The support rollers are fitted with nitrogen dampers to further reduce shock loading, so that the track unit provides greater stability, with improved ride and cornering, so enabling it to be used at road speeds of 30km/hr on the Lexion 780, 770, 760, 750 and 670, with the option of 40km/hr on the narrow-body Lexion 760.
A further new option on all Lexion 700 Terra Trac models is an automatic tyre pressure control system for the rear axle. This enables the operator, via Cebis, to set and alter the rear tyre pressure and to programme in differing pressures for in the field or for road work. The tyre pressure level is manually activated using a switch in the cab roof. However as soon as the road speed is engaged, the rear tyres are automatically inflated to the pre-set road pressure setting. The ability to reduce the rear tyre pressure will therefore help enhance the low ground pressure benefits of the Terra Tracs.
Other new features for the 2014 Lexion 700 and 600 range models include a rear-view camera that’s integrated into the rear hood with the image displayed in Cebis, which can be accessed using the Direct Access button or is engaged automatically when reversing.
For greater adjustment and improved cutterbar ground following, a new hydraulic top-link is now available for the feeder housing, with the angle displayed in Cebis. Previously only available on Lexion 700 models, the option of a central lubrication system has been extended to all Lexion 600 models, except Montana versions.
Lexion 600 models also benefit from a new four-wheel-drive axle, which incorporates two hydraulic motors fitted centrally in the rear axle. This not only provides improved power transmission and grip, along with reduced fuel consumption, but will also allow a wider range of tyre sizes to be fitted.
