LEXION 670 / 650

Committed to productivity.

More ideas and intelligent solutions that create an integrated system incorporating superior technology. For outstanding seasonal performance.

LEXION 670 / 650

Committed to productivity.

More ideas and intelligent solutions that create an integrated system incorporating superior technology. For outstanding seasonal performance.

Crop flow.

More performance from the feeder.

Straight cutterbar drive.

Reduce fuel consumption without reducing power – the straight cutterbar drive plays a key role in making this possible. The great benefit of this design is that it allows the power to be used to the full. Combine performance is increasing all the time, and with it the volume that has to be transported through the feeder housing. Drive systems have to be able to meet these growing requirements. Four different drives are available: S (constant), L (variable), XL (two-speed) and XXL (variable). CLAAS therefore offers the right drive for every range of applications and thus ensures maximum throughput.

Front attachment drive brake.

Effective protection against foreign bodies and other causes of damage: the drive brake (1) allows the front attachment to be stopped immediately, if necessary, by means of the multifunction control lever. As the drive brake is fitted directly to the feeder housing, only a small mass needs to be braked. This means less braking torque and less wear.

Hydraulic reverse.

Blockages are taken care of easily: the hydraulic system (2) enables protective reversing with high starting torque. The hydraulic reverse can be actuated conveniently with a toggle switch in the cab. The direction of rotation of the hydraulic reel drive also changes automatically, providing additional support for the reversing procedure.

LEXION 600

Optimised. The feeder housing.

Time to grow.

The extremely high performance of our LEXION combine harvesters begins with the feeder housing. A completely new feeder housing system ensures that we live up to our high standards. Conventional feeder housings use chains to link the feeder slats, but with this new design the feeder slats are connected via belts instead of chains. The belts are driven by means of teeth on the underside. This arrangement ensures both powerful feed action, even when working with large quantities of material, and powerful reversing. Compared with a conventional feeder housing, the belt conveyor offers a number of decisive advantages:

  • Smooth and quiet operation
  • Long service life and constant tension
  • High durability and high resistance to damage caused by foreign objects
  • Universal feeder housing.
    LEXION 600

    A shallow intake angle to the threshing components facilitates optimal crop flow. Rugged intake chains or belts with feeder slats ensure high stability, while a replaceable wear plate guarantees long service life.

  • HP feeder housing.
    LEXION 600

    The HP (header pitch) feeder housing allows manual adjustment of the cutting angle for optimal adaptation to all field conditions. The cutting angle can be moved 8° back and 11° forward from its central position. A top link on the feeder housing provides mechanical adjustment.

  • HP hydraulic feeder housing.
    LEXION 600

    Hydraulic adjustment of the cutting angle is performed by means of a hydraulic ram. The cutting angle can be stored along with the four possible cutting heights. In laid crops in particular, when short stubble is required, the cutterbar is always at the optimal cutting angle.

  • V channel feeder housing.
    LEXION 600

    With the flexible positioning of the cutterbar mount, the V feeder housing facilitates fast and easy mechanical adjustment of the cutting angle, even with a front attachment fitted. This ensures optimal adaptation to all field conditions and different types of tyres. The cutting angle is adjusted from a single central point and transmitted to both sides in parallel. The cutting angle can be read on a scale.

LEXION 600

More pre-acceleration. APS.

Unique APS threshing system.

Only CLAAS offers this outstanding high-performance patented system with a pre-accelerator in the threshing unit. CLAAS generates its decisive competitive edge well before the threshing drum, with dramatically improved acceleration of the crop flow from 3 m/s to 20 m/s, triggering a chain of extremely efficient processes:

  • The pre-accelerator separates the crop more thoroughly
  • The crop flow is particularly even and up to 33% faster
  • Higher centrifugal forces sort considerably more grains
  • Up to 30% of all grains are already sorted in the pre-separation concave directly below the accelerator, significantly reducing the load on the main concave

This delivers a net performance increase of up to 20% with no increase in fuel consumption.

LEXION 600

Top quality grain with the APS system.

The APS system is equipped with multistage adapters for optimal deawning. With the intensive threshing component and the deawning plates, which can be engaged in just seconds via a lever on the feeder housing, APS ensures outstanding grain quality.

  • Overload protection increases the daily output.

    The concave is adjusted hydraulically from the operator's seat. Parallel concave control provides the best quality of threshing. At the same time, integrated hydraulic overload protection reliably prevents damage from foreign objects and enables you to use the full capacity of the machine without risk.

  • Closed threshing drum.

    A closed threshing drum, which can be used for any crop, is available in addition to the open rasp bar threshing drum. This drum stands out with its optimised crop flow, which ensures even more protective handling of the crop, as well as improved grain quality.

  • Synchronised function.
    LEXION 600

    The accelerator, threshing drum and impeller can be driven by a central variator. Each change in drum speed causes a corresponding adjustment of the speed of the accelerator and impeller.

    The result is protective crop handling with even crop flow throughout.

  • MULTICROP concave.

    The pre-separation concave is designed as a MULTICROP concave capable of handling all types of crops. The three concave segments can be changed rapidly, minimising changeover times between crops and maximising efficiency and profitability.

LEXION 600

More safety and reliability. AUTO CROP FLOW.

Monitoring risks.

What can we do to make harvesting operations safer and more reliable? In extreme harvesting conditions, the operator needs to concentrate fully at all times in order to guarantee trouble-free operation. Often there are only a few days when grains can be harvested while at optimum quality – and it is precisely then that every minute of operation counts.

Early warning.

The following machine components are monitored to provide early warning of critical peak loads:

  • APS threshing unit
  • Straw blockage flap in straw walker compartment
  • Engine
  • Straw chopper and power spreader

Fast response.

If a preset slip limit is exceeded, the following measures are triggered automatically:

  • Cutterbar brake is activated
  • Feeder unit and front attachment are switched off
  • Cruise control or CRUISE PILOT: speed is reduced to 1.5 km/h if the systems are active
  • Grain tank unloading is switched off if it is active

These measures ensure that no more crop material enters the machine. This reduces downtime resulting from blockages or damage.

LEXION 600
LEXION 600
LEXION 600

Matched to harvesting conditions.

The AUTO CROP FLOW function, which monitors the crop flow automatically, can be switched on and off in CEBIS. In this way, the operator can choose whether or not to use the system. The sensitivity of the slip limits can be set in three stages to match the system optimally to the conditions in the field.

Operate at the performance limits.

The AUTO CROP FLOW function is intended to support the operator in operating the machine at its performance limits. It provides the necessary safety margin by automatically monitoring the components relevant to the crop flow and initiating the necessary measures.

LEXION 600 straw walker / 2013

More residual grain separation.

Effective straw walker technology.

The APS threshing system operates so efficiently that only about 10% of the grains run through the residual grain separation stage in the LEXION. 90% of the grains have already been separated from the straw by APS.

The even flow of straw on the open-bottomed straw walkers with an extreme gradient angle ensures that practically all residual grain is separated from the straw.

A separate returns pan sends the grains on their way to the preparation floor.

Residual grain separation occurs over a total length of 4400 mm across four straw walker steps. The LEXION 670 and 650 models are equipped with six straw walkers. Centre and side extensions are available. Even large volumes of straw are transported quickly and easily.

LEXION 600

MSS increases output.

MSS actively fluffs the crop with multiple controlled tines which dig into the straw. The tines reach into the mat of straw from above and aerate it whilst simultaneously speeding it up to ensure active control of the crop flow. The straw mat is thinned as a result, making it easier for the remaining grains to fall out. The available length of the straw walkers is used more effectively, while optimising the structure and quality of the straw. The intensity of the tine action can be adapted to a range of harvest conditions.

MSS loosens things up.

Thorough loosening of the straw mass is critical for high separation efficiency, particularly under difficult field conditions such as wet straw or green growth. This is why all LEXION straw walker combines are equipped with the multifinger separation system (MSS), a drum with controlled tines positioned above the straw walkers. MSS ensures effective residual grain separation under any conditions.

LEXION 600 cleaning system / 2013

More thorough cleaning. For impressive results.

LEXION 600
LEXION 600

Electric sieve adjustment

LEXION 600

Divided preparation floor that can be pulled out towards the front

  • Two-stage pre-cleaning.
    LEXION 600

    A dual ventilated straw walker step ensures intensive pre-cleaning. A multi-stage turbine fan, which is continuously adjustable from the cab, creates the necessary air flow. The fans ensure constant, evenly distributed air pressure, even with varying sieve loads, effectively increasing the cleaning capacity.

  • Electric sieve adjustment.

    For convenience, even the sieve can be adjusted electrically from the cab.

    • Easy and convenient
    • No need to exit the cab
    • Immediate monitoring of results
  • Preparation floor.

    The crop is pre-sorted into grains (bottom) and chaff and broken straw (top) on the preparation floor, thereby reducing the loads on the upper sieve and increasing the cleaning capacity. The six individual plastic elements of the preparation floor can be easily pulled out towards the front for cleaning after harvesting is complete.

  • 3D cleaning system.
    LEXION 600
    • Dynamic side slope levelling via active control of the upper sieve
    • Completely consistent performance on side slopes up to 20%
    • No wear - completely maintenance free
    • Fast, simple retrofitting
    • Ideal "hillside package" in combination with AUTO CONTOUR
  • Returns and the GRAINMETER.
    LEXION 600

    The fill level and composition of the returns allow conclusions to be drawn about the best equipment settings to use. The cab also enables the operator to view the well-lit returns directly while seated.

    All LEXION models can be fitted with a GRAINMETER in addition to the fill level indicator (1). The electronic returns quality display also allows the grain ratio (2) in the returns to be conveniently checked in CEBIS.

    This data enables the operator to optimise the equipment settings manually to utilise the full production capacity of the LEXION.

LEXION 600

AUTO SLOPE. Automatic fan control.

Meet challenges.

Harvesting undulating fields with the machine presents its cleaning system with a particular challenge: when the machine is operated uphill, the fan speed must be reduced to prevent grain losses from the sieve pan.

Conversely, the fan speed must be increased during downhill operation to maintain the crop flow in the cleaning system and to ensure that the grain is separated. AUTO SLOPE continuously adjusts the fan speed to the given conditions based on the fan speed preset by the operator.


CRUISE PILOT: automatic forward travel control.

The CLAAS CRUISE PILOT automatically controls the harvesting speed for optimal results on the basis of the engine load. Depending on the travel mode, the system uses various machine parameters simultaneously for control: ground speed, crop volume in the feeder housing and grain losses.

The following travel modes are available, with parameters always adjusted on the basis of engine load:

  • Constant speed – specified target speed
  • Constant throughput – specified target throughput
  • Constant throughput and losses – specified target throughput and loss rate

The factor responsible for restricting the harvesting speed, e.g. engine load, losses or throughput, is indicated in CEBIS.

To enable superior control of the LEXION’s power, you can set a maximum speed and five control response levels with quick, easy operation via the HOTKEY.

How you benefit:

The predictive CRUISE PILOT system responds before peak system loads occur. This automatically keeps your LEXION running at the upper limit of productivity at all times and delivers better harvest results.

LEXION 600

Unloading mode for the CRUISE PILOT.

If offloading takes place during the harvesting process, the operator can preselect one of two different strategies: CRUISE PILOT does not take account of the unloading process and carries on making continuous adjustments to the forward speed. Unloading mode Offloading: The forward speed is maintained at a constant setting during the unloading process. The CRUISE PILOT is deactivated temporarily. This can make loading the transport vehicle easier.

More adjustment per second. CEMOS AUTOMATIC.

CEMOS.

CEMOS is the CLAAS umbrella term for all the systems which optimise machine performance. There are two different CEMOS versions:

  1. Dialogue-based systems, such as CEMOS DIALOG or CEMOS Advisor. These guide the operator through a number of steps in order to achieve the optimum machine configuration. This process requires the operator to confirm the suggested settings or apply them manually.
  2. CEMOS AUTOMATIC, the term which covers various functions which optimise the machine and a particular process entirely automatically. All the operator has to do is activate the automatic system. The functions include CEMOS AUTO CLEANING, which optimises the cleaning process, and CEMOS AUTO SEPARATION, which optimises the ROTO PLUS residual grain separation.
LEXION 600

The new CEBIS MOBILE keeps you in the picture.

The current conditions of all major assemblies and active CEMOS AUTOMATIC functions are shown. The image from the GRAIN QUALITY CAMERA can also be shown. In this way, the operator can keep an eye on all the relevant information and adapt the operating strategy if necessary.

New look and operating concept for CEMOS.

The new CEBIS MOBILE touchscreen terminal allows the following functions to be controlled:

  • CEMOS DIALOG
  • CEMOS AUTO CLEANING
  • CRUISE PILOT
  • AUTO CROP FLOW
LEXION 600

CEMOS AUTO CLEANING.

Optimisation strategies.

The operator can choose from various optimisation strategies:

  • Maximum throughput
  • Minimal fuel consumption / straw quality
  • High grain quality
  • Optimum balance

The selection made by the operator specifies the result which CEMOS AUTO CLEANING is to deliver in accordance with the required strategy. CEMOS AUTO CLEANING then automatically controls cleaning functions in order to achieve this result optimally.

The operator retains full control at all times.

CEMOS AUTO CLEANING operates systematically on the basis of the CEMOS DIALOG software. The operator can intervene at any time and use dialogue functions in CEMOS to establish the correct settings. The automatic system remains active in this situation.

CEMOS DIALOG and CEMOS AUTOMATIC are linked. CEMOS DIALOG therefore handles the entire machine monitoring aspect and can provide additional operating suggestions in the form of text messages. Touching a text message opens a dialogue window with the relevant system suggestions.

Display and operation.

CEMOS AUTO THRESHING and CEMOS AUTO CLEANING can each be controlled and monitored via the machine's CEBIS terminal or the CEBIS MOBILE terminal. The CEBIS MOBILE terminal provides the operator with a permanent overview of all the functional units of the machine and their settings. The machine's CEBIS terminal can only be used to control the units; it does not provide an overview of them. CEMOS AUTO THRESHING is only available in combination with the new CEBIS MOBILE.

Fully automatic grain cleaning.

Touching the image opens a dialogue window for adjusting sensitivity. This allows the operator to set the required level of grain cleaning.

CEMOS AUTO CLEANING then optimises the cleaning process continuously if the required level has not yet been attained.

LEXION 600

More dialogue. CEMOS DIALOG.

Operators benefit, results improve.

CEMOS DIALOG is an impressive, reliable partner for operators, motivating them to optimise combine performance by adapting settings to the given situation. CEMOS DIALOG provides a sense of security and increases skills through ongoing learning.

  • CEMOS DIALOG - the right approach for the right setting.

    CEMOS DIALOG meets the desire for an assistant capable of finding the right combine settings every time, balancing performance, quality, safety and efficiency. The CLAAS-specified values in the crop log constitute good averages for nearly any harvesting conditions, but there is usually room for optimisation. CEMOS helps to utilise this potential consistently.

  • CEMOS DIALOG with new operating concept.

    CEMOS DIALOG operating and display functions are controlled through the new CEBIS MOBILE terminal. The main display area shows the current status of all functional units.

  • Tried and tested.

    CEMOS DIALOG has proven outstandingly successful in practical use. Our customers have confirmed increases in throughput many times over. Another recognised benefit for the operator is the learning effect which results from continuous communication with CEMOS.

CEMOS Advisor app.

The CEMOS Advisor app is available free of charge for all LEXION, TUCANO and AVERO combine harvester models. Based on the CEMOS DIALOG logic, the CEMOS Advisor app supports the configuration of combine harvester settings. A lost grain calculation is also included for results monitoring.

LEXION 600

A working dialogue.

CEMOS DIALOG guides the operator to the best settings using a screen dialogue. Optimisation takes place in three stages:

  1. The operator requests a suggestion for a setting (for example, to reduce losses)
  2. CEMOS DIALOG makes a logical setting suggestion
  3. The operator accepts this setting suggestion or rejects it

Steps 2 and 3 are repeated until the operator is satisfied with the result or CEMOS DIALOG has no further suggestions. Equipment adjustments (such as fan speed) are performed by CEMOS DIALOG whenever possible but must always be confirmed by the operator.

No adjustments are made automatically without operator confirmation. Nearly every CEMOS DIALOG screen offers comprehensive help. If a manual adjustment is necessary, CEMOS DIALOG displays an image to illustrate the setting for the operator.

Suggestions for mechanical adjustments.

Since CEMOS DIALOG takes the entire crop flow into account, the operator can also request suggestions for adjustments to mechanical components. If, for example, a crop flow problem arises in the cutterbar, CEMOS DIALOG provides relevant text messages and illustrations to assist the operator in troubleshooting.

LEXION 600

More grain in the tank.

LEXION 670 TERRA TRAC with a grain tank of up to 12,000 l.

Once the threshing, residual grain separation and cleaning systems have done their work, the cleaned grain is collected in the automatically expandable grain tank. With an even greater volume – now 12,000 litres – the LEXION once again demonstrates its capacity for high productivity, enhanced by many other strengths.

The choice is yours.

With the LEXION, you can select whichever grain tank capacity best meets your requirements.

With a maximum discharge rate of 130 litres per second, the grain tank is emptied completely in less than two minutes. Grain tank unloading tubes of different lengths ensure that the right configuration is always available for the various cutterbar widths.

  • PROFI CAM – everything in view.
    LEXION 600

    All LEXION models can be equipped with a PROFI CAM at the end of the grain tank unloading tube. This camera position has been chosen precisely to allow up to three processes to be monitored simultaneously on a colour display from the comfort of the cab:

    • Grain tank unloading tube deployed: transfer process
    • Grain tank unloading tube retracted: distribution of chopped material
    • Grain tank unloading tube retracted: rear of machine during reversing or on-road operation
  • The QUANTIMETER measures and checks.

    The primary functions of the QUANTIMETER are throughput measurement, moisture content measurement and data display in CEBIS. The moisture content of the crop is monitored continuously and displayed upon request. During the volume measurement in the grain elevator, a photo cell records the filling of the individual paddles. Using appropriate correction factors, including the transverse and longitudinal tilt of the machine among other things, the QUANTIMETER automatically determines the precise quantity harvested.

  • CEBIS rear camera.

    The image from the camera fitted on the rear hood is fed straight to the CEBIS screen. There is no need for an additional screen in the cab.

    The image from the camera is displayed automatically on the CEBIS screen as soon as the multifunction control lever or CMOTION is used to move the LEXION backwards. It is also possible to use the DIRECT ACCESS button to call up the image from the camera.

LEXION 600

Greater performance. Greater convenience. The straw chopper.

For more throughput.

Sometimes, bigger is better. Crop intake and transport are improved significantly by the increased diameter of the straw chopper. The extended floor of the straw chopper extends the transit time of chopped material and accelerates the material to a significantly greater degree. When used with the standard deflector, this increases the projection distance and spreading quality dramatically.

CLAAS straw management. With SPECIAL CUT.

From the straw walkers, the straw moves directly to the chopper, which can be varied in intensity depending on the operating conditions. Up to 88 closely arranged dual bladed knives, a cross blade and a static knife array are the recipe for finely chopped straw. The LEXION also has a swivelling grating element for the best straw chopping and spreading. The finely chopped material is subsequently fed to the power spreader.

  • Convenient optimisation of chopping quality.

    In the straw chopper, both the swivelling grating element and the static knife array can be adjusted hydraulically. This means that the chopping quality can be adjusted in CEBIS while the machine is working, thereby enabling a flexible reaction to field conditions. A mechanical adjustment system, which is operated by two levers without the need for any tools, is also available.

  • Switchover to swathing from the cab.

    Needing to get out of the cab is now a thing of the past, at least when it is a matter of switching the straw chopper from swathing to spreading chopped material. This task can be performed effortlessly from the cab via CEBIS. If only certain parts of a field need to be chopped, the operator can switch the machine over in a matter of seconds.

LEXION 600

More efficiency. More precision. The power spreader.

Mechanically driven power spreader.

Perfect straw spreading of the highest quality is guaranteed by the mechanically driven power spreader. The two counter-rotating spreading rotors are driven by a belt and therefore always run at a constant speed. This unique drive concept ensures consistent spreading quality.

Precise spreading of chopped material and chaff.

Both the chopped material and the chaff from the cleaning system are caught in motion by the power spreader and accelerated further. This approach, together with a mechanical drive, keeps the power requirement down and makes for low fuel consumption.

Performance map-controlled spreading.

Each spreading rotor has two movable deflectors whose spreading widths can be adjusted either together or separately. This allows the system to be adjusted to any conditions encountered in practice. In this way, the LEXION is able to spread straw efficiently using minimal energy – even under very unfavourable conditions such as extremely high straw volumes, differing degrees of straw moisture, strong crosswinds or sloping terrain.

  • The power spreader in chopping mode.

    The straw chopper feeds the material straight to the power spreader. The power spreader accelerates the crop flow again and spreads the material across the entire working width.

  • The power spreader during swathing.

    In swathing mode, the power spreader is simply folded away downwards and the drive is completely disengaged. The power spreader is now stationary and no longer requires any power. Chaff and short straw from the sieve pan are now spread by the chaff fan.

  • Combination of power spreader and chaff fan.

    In swathing mode, the power spreader is simply folded away downwards and the drive is completely disengaged. The power spreader is now stationary and no longer requires any power. Chaff and short straw from the sieve pan are now spread by the chaff fan.

Even chaff distribution.

From the sieve pan, the short straw and chaff are routed to the chaff spreader or the chaff fan. The chaff spreader is hydraulically driven and spreads the sieve pan discharge evenly behind the machine. The speed and spreading width can be adjusted individually with a flow control valve.

Automatic crosswind compensation.

Crosswinds affect the discharge direction of the chopped material. This results in inconsistent straw distribution and chopped material at the crop edge, which can inhibit the crop flow in the cutterbar. The remedy: sensors at the rear of the machine detect the strength of the crosswind, and the discharge direction of the chopped material is adjusted to compensate. The resulting benefits are automatic, uniform distribution of the chopped material and a reduced workload for the operator.

Automatic discharge direction adjustment when operating on sloping terrain.

When the machine is operating on sloping terrain, gravity keeps the sensors at the rear vertical at all times. The automatic discharge direction adjustment system also enables uniform distribution of the chopped material across the entire working width when operating on sloping terrain, thereby reducing the operator's workload in crosswinds and when working in sloping terrain.
