Crop flow.

The APS HYBRID SYSTEM – threshing technology from CLAAS – represents the combination of two outstanding technologies: the tangential APS threshing system and the highly efficient ROTO PLUS residual grain separation system.

Crop flow.

More performance from the feeder.

Straight cutterbar drive.

Lower fuel consumption without any loss in power – the straight cutterbar drive plays a key role in making this pos-sible. The great benefit of this design is that it supports the full utilisation of all available power. As the performance of combines keeps increasing, the volumes that need to be conveyed through the feeder housing also grow, and drive systems therefore need to cope with these increased 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.

LEXION 770-750

Front attachment drive brake.

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

Hydraulic reverse.

Blockages are taken care of easily; the hydraulic system 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 770-750

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 770-750

    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 770-750

    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 770-750

    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 770-750

    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.

More top technology. APS HYBRID SYSTEM.

More than the sum of its high-performance parts.

The APS HYBRID SYSTEM – threshing technology from CLAAS – represents the combination of two outstanding technologies: the tangential APS threshing system and the highly efficient ROTO PLUS residual grain separation system.

Only CLAAS integrates both systems in one machine, with APS giving you a significant competitive edge over other systems.

This powerful duo offers you unbeatable advantages:

  • Drum speed adjustment in the threshing system independent of rotor speed
  • Individual adaptation of the entire process to changing field conditions over the course of the day
  • Protective threshing with top throughput

Far ahead of the others.

With its effective residual grain separation system, crop flow speeds 10 times faster between the rotors and concaves and the high centrifugal force, the LEXION with the APS HYBRID SYSTEM offers separation qualities that differ fundamentally from straw walkers.

Take advantage of the unbeatable combination of APS + ROTO PLUS.

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.

  • Closed threshing drum.
    LEXION 770-750

    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.

  • 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.

  • 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.

  • Synchronised function.
    LEXION 770-750

    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 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.

LEXION 770-750

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

  • APS threshing unit
  • ROTO PLUS rotors in the residual grain separation system
  • Engine

In the straw management area, the system detects if the straw chopper and power spreader are stationary.

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 770-750

Matched to harvesting conditions.

The AUTO CROP FLOW function can be switched on and off in CEBIS. This allows the operator to choose whether to use the system or not. The sensitivity of the slip limits can be set at three levels 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.

CLAAS LEXION 700. ROTO PLUS.

Even further ahead in residual grain separation. ROTO PLUS.

A superior integrated concept.

The unique APS enhanced by the exclusive ROTO PLUS concept results in the superior technology of the APS HYBRID SYSTEM, which once more impressively demonstrates the CLAAS advantage.

ROTO PLUS post-threshing grain separation.

The even feed of the APS creates ideal conditions for the separation of the remaining grain with ROTO PLUS. The principle behind ROTO PLUS is simple but extremely effective. The impeller of the APS threshing unit divides the straw into two flows of material and feeds them to the two counter-rotating, high performance rotors.

  • High-performance rotors.

    Eccentrically mounted rotors generate tremendous centrifugal force to separate the remaining grains from the straw. With a diameter of 445 mm and a length of 4.20 m each, the rotors in the LEXION provide a huge separation area. The mixture of grain, straw and chaff first reaches the preparation floor through the returns pan before passing over the straw walker steps to the sieve pan. This significantly reduces the load on the sieve pan.

  • Conveniently adjustable rotor flaps.
    LEXION 770-750

    Automatic control by CEMOS AUTOMATIC.

    Automatic control by CEMOS AUTOMATIC.

    All LEXION models have hydraulically operated shutters to adjust the rotor separation area. The HOTKEY rotary switch is turned to reduce the open separation area of the rotor concave in steps simply and easily from the cab. This reduces the sieve load under very dry conditions and under wet field conditions the large separation area achieves more effective separation of residual grain. The result of variable rotor separation area adjustment is maximum throughput under all harvesting conditions.

  • Continuously adjustable variator.

    Automatic control by CEMOS AUTOMATIC.

    The rotor speed can be continually adjusted with ease from the operator’s seat with the CEBIS rotary switch, anywhere from 350 to 1050 rpm regardless of the threshing drum speed. This allows quick adjustment of the rotation speed to different crops as well as harvesting and straw conditions, making it easy to achieve the best work rates with the combine.

LEXION 4D-cleaning system / 2016 / en

CLAAS 4D-cleaning system.

Meet challenges.

Using the machine to harvest fields which are not level presents the cleaning system with a particular challenge. With the machine running along a side slope, the material in the residual grain separation system moves to the side of the returns pan closest to the bottom of the slope. As a result, the preparation floor and the sieves are loaded on one side only. And when the machine is running up or downhill, the fan speed and the sieve position have be adjusted in order to attain the optimum cleaning performance and avoid losses.

The CLAAS 4D-cleaning system.

The 4D-cleaning system is another module within CEMOS AUTOMATIC. It comprises the 4D function to control the rotor flaps and AUTO SLOPE to adjust the fan speed.

Central components: the rotor flaps.

The scope of the 4D-cleaning system includes a third pair of rotor flaps under the third separator concave. Furthermore, the individual rotor flap segments are divided so that the left or right half can be opened and closed separately.

  • How it works.

    In order to ensure even loading of the cleaning system, 4D controls the rotor flaps on the basis of the transverse and longitudinal tilt as well as the current load on the cleaning system. In this way, the cleaning performance remains almost constant, even in difficult terrain. 4D adjusts the position of the rotor flaps automatically, acting in the background as an aid to the operator.

  • How does 4D work?

    On a side slope:

    • The uphill half of the rotor flap segment is opened
    • The downhill half of the rotor flap segment is closed

    The rotor flaps close sequentially from front to rear and open sequentially from the rear to the front (relative to the direction of travel in both cases).

    When moving uphill:

    • Fan speed is reduced
    • Lower sieve is opened wider

    When moving downhill:

    • Fan speed is increased
    • Lower sieve is closed further
  • Benefits.
    • Uniform distribution of material from residual grain separation process
    • Although machine is operating on an incline, there is even loading of the returns pan, preparation floor, upper sieve / lower sieve
    • The fan speed is adjusted automatically
    • Improved sieve pan performance through adjustment of air volume
    • Cleaning performance remains stable when operating on transverse and longitudinal slopes (in undulating terrain)
    • Greater throughput and reduced losses on slopes
LEXION 770-750

More thorough cleaning. For impressive results.

JET STREAM / 2015 / en

JET STREAM.

The JET STREAM cleaning system is designed especially to work with the ROTO PLUS residual grain separation system.

  • Dual ventilation step
  • Height of the first step: 150 mm
  • The long flow compensation channel ensures a consistent, extremely strong air blast
  • 8-stage turbine fan (LEXION 770)
  • 6-stage turbine fan (LEXION 760/750)
  • Electrical sieve adjustment from the cab

Automatic control by means of AUTO CLEANING and AUTO SLOPE.


The easy way to make the most of any incline.

AUTO SLOPE. Automatic fan control.

Hilly terrain calls for extra concentration on the part of the operator. This is precisely why the AUTO SLOPE function provides support for adjustment of the cleaning system. If the machine is operating uphill, the fan speed must be reduced in order to avoid 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.

LEXION 770-750

Gold for CEMOS AUTO THRESHING at Agritechnica 2017

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.
  • Harvest more – adjust less.

    All CEMOS AUTOMATIC functions adjust the machine continuously and automatically in line with the current harvesting conditions. They provide maximum throughput with top grain quality and outstandingly clean grain while keeping fuel consumption to a minimum. All the operator has to do is activate the automatic functions.

  • Automatic threshing, separation and cleaning.

    CEMOS AUTO THRESHING finds the best setting for:

    • Threshing drum speed
    • Threshing concave distance

    CEMOS AUTO CLEANING optimises the cleaning process by adjusting the following:

    • Fan speed
    • Upper sieve opening
    • Lower sieve opening

    CEMOS AUTO SEPARATION acts on the ROTO PLUS residual grain separation system and adjusts the following:

    • Rotor speed
    • Rotor flap position
  • Functional principle.

    When the combine starts work in the field, the CEMOS AUTOMATIC functions configure the machine to comply with certain preset values, quickly establishing the optimal setting for the work systems. Taking account of the changing harvesting conditions throughout the course of the day, this optimum configuration is repeatedly checked and continuously adjusted. As a result, the CEMOS AUTOMATIC functions carry out continuous readjustment on a scale which no operator would be able to achieve manually.

  • Range of applications.

    CEMOS AUTO CLEANING and CEMOS AUTO SEPARATION are used for wheat, barley, triticale, rye, oats1, rapeseed, maize and soybeans1. These functions are therefore available throughout the entire harvest season.

CEBIS MOBILE keeps you in the picture.

The current conditions of all major assemblies and active CEMOS AUTOMATIC functions are shown. In addition, the status of the 4D-cleaning system is indicated. 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.

4D-cleaning system status display.

The secondary display area can be configured to show the status of the 4D-cleaning system. This means that the current position of the rotor flaps is visible. CEMOS AUTO SEPARATION adjusts their position continuously in accordance with the required separation performance or straw moisture.

Look and operating concept for CEMOS.

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

  • CEMOS DIALOG
  • CEMOS AUTO THRESHING
  • CEMOS AUTO CLEANING
  • CEMOS AUTO SEPARATION

  • AUTO CROP FLOW

Optimisation strategies.

More capacity is used.Checked and proven.

The optimisation strategies are based on agricultural economics parameters:

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.


LEXION 770-750

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.

More grain in the tank.

A perfect fit.Solutions for controlled traffic farming.

The VARIO 1230, 1080 and 930 cutterbars are a perfect fit for 12 m, 10 m and 9.0 m controlled traffic farming systems. CLAAS can provide the appropriate grain tank unloading tubes for these cutterbars.

In this way, the transfer vehicle can run in the track left by the combine harvester. The VARIO 1230 is used in combination with the 7 XL grain tank unloading tube for 12 m controlled traffic farming systems. The 7 XL grain tank unloading tube is simply folded for on-road travel.

LEXION 770-750

Convenient yield checking.

The large window in the back wall of the cab allows convenient visual inspection of the harvested crop. The interior of the grain tank is illuminated for work at night. An inspection port provides constant access so samples can be taken manually any time. The sample cup, which is always to hand in the space provided in the inspection port, also serves as a calibration container for determining the bulk density.

LEXION 770-750

Grain tank capacity of up to 13,500 l.

After the threshing unit, residual grain separation and cleaning systems have done their work, the cleaned grain is collected in the expandable grain tank. Here too, with a large volume of up to 13,500 litres, the LEXION demonstrates its capacity for high performance, enhanced by numerous other strengths.

LEXION 770-750

PROFI CAM – everything in view.

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 an additional 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
LEXION 770-750

CEBIS rear camera.

The image from the rear 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.

Up to four cameras can be connected to the system and simultaneously feed their images to the colour monitor as well as the S10 terminal in the cab.

LEXION 770-750

More performance. More convenience. The new straw chopper.

For more throughput.

Sometimes, bigger is better. Crop intake and transport are improved significantly by the increased diameter of the new 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 rotors, the straw moves directly to the chopper, the intensity of which can be varied depending on the conditions. Up to 108 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 new straw chopper, both the friction concave plate 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 770-750

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. The new power spreader really comes into its own in fields characterised by changing conditions (dry standing straw, wet and heavy laid straw).

LEXION Power spreader / 2016 / en

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.

    Short straw and chaff are routed from the sieve pan to the chaff fan. The chaff fan feeds the material straight to the power spreader. In this way, the mixture of chaff and short straw, which can account for up to 25% of the total throughput, is fed into the active spreading system which spreads it across the entire working width.

LEXION 770-750

More effective spreading.

Automatic discharge direction adjustment.

All LEXION models with a power spreader can be equipped with two sensors for automatic adjustment of the direction in which the chopped material is discharged. The sensors are fitted on the light brackets at the left and the right of the machine. The operator can adjust the sensitivity of the sensors easily using CEBIS.

LEXION 770-750

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.

LEXION 770-750

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.

LEXION 770-750

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.
