Crop flow. Committed to productivity.

LEXION 770-750

Optimised.The feeder housing.

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 now, instead of chains, belts are used to link the feeder slats with each other. The belts are driven by means of teeth on the underside. This arrangement ensures a powerful feed action, even when working with large quantities of material, as well as powerful reversing. Compared with a conventional feeder housing, the belt conveyor has a number of decisive advantages:

  • Smooth and quiet operation
  • Long service life and constant tension
  • Very durable and resistant to damage caused by foreign objects
  • Universal feeder housing.
    LEXION 770-750

    A shallow intake angle to the threshing parts 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 to adapt to all field conditions. From the central position the cutting angle can be moved 8° back and 11° forward. The mechanical adjustment is performed by means of a top link on the feeder housing.

  • 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 channel 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 one central point and transmitted in parallel to both sides. The cutting angle can be read on a scale.


More top technology. APS HYBRID SYSTEM.

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


More pre-acceleration. APS.

  • 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

Thus there is a net performance increase of up to 20% with no rise in fuel consumption.

LEXION 770-750

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.

LEXION 770-750

Synchronised function.

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.


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.

    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.
    LEXION 770-750

    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.

More thorough cleaning. For impressive results.

JET STREAM / 2015 / en


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.

LEXION 770-750

Dual ventilation.

A dual ventilated step ensures intensive pre-cleaning while the multi-stage turbine fans, which can be adjusted continuously from the cab, create the necessary air flow.

Preparation floor.

Pre-sorting of the grains (bottom) and chaff and broken straw (top) takes place on the preparation floor. The resulting reduction in the load on the upper sieve increases the cleaning capacity. The six (LEXION 770) individual plastic elements - or four in the case of the LEXION 760 / 750 - can be easily pulled out to the front for cleaning the preparation floor after harvesting is completed.

NEW: 12-metre Controlled Traffic system.

Complementing the VARIO 1230 cutterbar used for the 12-metre Controlled Traffic system, the corresponding grain tank discharge auger tube for the LEXION 770, 760 and 750 TERRA TRAC models is now available. During on-road travel, the rear section of the grain tank discharge auger tube is simply retracted.

NEW: 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

More performance. More convenience. The new straw chopper.

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 increases the duration of the transit of the chopped material and accelerates it to a significantly greater degree. When used with the standard deflector, this increases the projection distance and spreading quality drastically.

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.

LEXION 770-750

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

Performance-map-controlled spreading.

Each spreading rotor has two movable deflectors whose spreading width 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 such unfavourable conditions as extremely high straw volumes, differing degrees of straw moisture, strong crosswinds or sloping terrain.

LEXION 770-750

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.
