Unique APS threshing system

Only CLAAS offers this outstanding, high performance patented system. The decisive competitive edge of CLAAS can be seen well before the threshing drum. The significantly increased acceleration of the crop flow from 3 m/s to 20 m/s triggers a chain of extremely efficient processes.

MULTIFINGER SEPARATION SYSTEM (MSS)

The MSS ensures effective residual grain separation under all conditions. Intensive fluffing of the straw mass is critical for high separation efficiency, particularly when field conditions are difficult. This is why all LEXION APS straw walker combines are equipped with MSS, a drum with controllable tines positioned over the straw walkers.

Straw management: convenient and efficient

It is now possible for the task of changing over from swathing to chopping as well as adjusting the static knife array and the rasp bar in the straw chopper to be performed from the cab. Thanks to the increased diameter of the new straw chopper, the chopped material is accelerated to a significantly greater degree and the spreading quality is optimised. 

NEW: Perkins engine

Perkins engines with displacements of 12.5 litres (LEXION 670) and 8.8 litres (LEXION 650) ensure outstanding power delivery with low fuel consumption.

Crop flow. Committed to productivity.

Claas Lexion feeder housing

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
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
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
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
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.

Unique APS threshing system

Only CLAAS offers this outstanding high performance patented system with a pre-accelerator in the threshing unit. The decisive competitive edge of CLAAS appears well before the threshing drum, with dramatically improved acceleration of the crop flow from 3 m/s to 20 m/s, which triggers 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

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

Synchronised function

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 the grain is separated from the straw.

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

Residual grain separation occurs on a total length of 4400 mm across four straw walker steps. The LEXION 670/660/650 models are equipped with six straw walkers and the LEXION 630/620 models with five. Centre and side extensions are available. Even large volumes of straw are transported quickly and easily.

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 over the straw walkers. It ensures effective residual grain separation under all conditions.

Returns and the GRAINMETER

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

In all LEXION models, the fill level indicator can be complemented by the GRAINMETER. The electronic returns quality display also allows convenient checking of the proportion of grain in the returns in CEBIS.

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

Grain tank. The choice is yours

PROFI CAM – everything in view
All LEXION models can be equipped with a PROFI CAM at the end of the grain tank discharge auger 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 discharge auger tube deployed: transfer process
  • Grain tank discharge auger tube retracted: distribution of chopped material
  • Grain tank discharge auger tube retracted: rear of machine during reversing or on-road operation
Up to four cameras can be connected to the system and simultaneously feed their images to the colour monitor in the cab.
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.

More performance. More convenience. The straw chopper.

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 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 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 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.

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

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.

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.

Direct view.

Sometimes a glance into the grain tank can tell you more than any number of sensors. A large inspection window in the back of the AVERO cab enables visual yield monitoring, so the returns can be viewed conveniently from the operator's seat. The inspection window is illuminated for better visibility.

Engine. Using brawn and brains to get the job done.

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.

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.
