Crop flow.

New features that make the feeder so effective:

• Belt conveyors for V and HP feeder housing are more robust and require less maintenance than chains
• Belt conveyors provide stability and operating reliability
• Dust extraction with enlarged cross-section delivers even greater cleaning performance
• The additional fan on the feeder housing prevents dust deposits
• The height of the feed roller can be adjusted in the HP feeder housing without tools
• A lowered floor plate enables even higher throughputs

The V feeder housing.

The V feeder housing allows you to carry out fast, mechanical adjustment of the cutting angle. The height of the guide roller can be adjusted easily. You can order the V feeder housing ex factory with chain or belt conveyors as well as with an open or closed guide roller.

The advantage for you:

By adjusting the cutting angle, you can harvest lodged crops, soybeans and grass more easily and with reduced losses as the tendency for the crop to pile up is reduced.

HP feeder housing.

Using the multifunction lever in the cab, you can perform continuous hydraulic adjustment of the cutting angle of the HP feeder housing from –8° to +11° – when running at full speed with the front attachment fitted. You can store a separate cutting angle for each of four cutting heights in CEBIS.

The advantage for you:

Easy cutting angle adjustment in response to changing crops (lodged crops), threshing crops (soybeans, grass) or terrain conditions (slopes, undulating terrain).

Standard feeder housing.

The standard feeder housing with a manual tensioning system is available with chain or belt conveyors as well as with an open or closed guide roller. The simplified height adjustment procedure for the guide roller enables a fast changeover from maize to small grains.

The advantage for you:

Can be used universally for all cutterbars with a working width of up to 12.30 m or for maize pickers up to 12 rows.

Exceptional throughput.

Numerous adjustment options increase straw quality as well as throughput. These include the parallel, independent adjustment of the threshing and separator concaves, the threshing drum speed reduction gearbox and the pivoting concave bar. The APS system (APS: Accelerated Pre Separation) accelerates the crop flow smoothly to as much as 20 m/s and generates high centrifugal force for maximum separation performance across all concave areas.

Advantages:

• Smooth acceleration of crop flow to as much as 20 m/s under the threshing drum.
  
• Threshing drum enlarged by 26% for optimal crop flow.
• Large, additional separator drum with active separation delivers greater throughput.
• Can be engaged hydraulically via CEBIS for fast adjustment to the threshing conditions.
• Can be engaged hydraulically from the cab or manually from the outside in the event of a change in harvesting conditions.
• The preconcave and threshing concave are adjusted in parallel. The drum speed changes are synchronised.

Increase throughput by 25%.

The new APS SYNFLOW WALKER threshing system opens up a new category in the straw walker combine harvester segment. It brings together the accelerated crop flow provided by APS with an additional separator drum after the threshing drum. In this way, you can benefit from exceptional throughput rates with excellent straw quality at the same time.

Synchronised speed adjustment.

The threshing drum speed can be matched easily to all conditions and crop types. It can be adjusted in CEBIS to any setting between 330 and 930 rpm. The speeds of the accelerator drum, the separator drum and the impeller change in synchronisation.

Easy actuation of preconcave flap and threshing concave flap.

In order to react to a change in crop type or for flexible adjustment of the friction path in the threshing and separation sections, the operator can engage the preconcave flap and the threshing concave flap manually from outside. The threshing concave flap is also available with optional hydraulic adjustment. When this option is specified, it can be operated conveniently from the cab and is integrated in CEMOS AUTO THRESHING.

Change concave segments quickly.

Changeover times from one crop type to another are getting ever shorter. When a changeover is carried out, the main components of the threshing concave remain in the machine. You can quickly change the preconcave segments through the stone trap simply by pulling the threshing concave segment out to the side. The numerous combination options are the key to the unique MULTICROP capability of the LEXION.

New features that optimise your secondary separation:

• An additional separator drum with a diameter of 600 mm makes for even more efficient secondary separation
• The separator concave can also be set in two positions
• Together, all these features increase the separation performance, even under difficult harvesting conditions

In addition to larger sieve areas and a bigger grain auger, there are three key differences compared with the standard cleaning system:

• A 56% higher first step
• A long airflow equalisation duct with the airflow oriented upwards
• An additional turbine fan unit

The 3D cleaning system makes a difference on slopes.

Using active transverse control of the upper sieve, the 3D cleaning system provides dynamic compensation for side slopes of up to 20%. The material is distributed evenly across the sieves, the cleaning performance remains absolutely stable. In combination with AUTO CONTOUR, this maintenance-free system forms an ideal hillside package.

The preparation floor reduces the load on the upper sieve.

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

The sieves are electrically adjustable.

The upper and lower sieves with their large sieve areas move counterdirectionally for high-performance cleaning. In addition, special sieve webs and rounded louvres direct the airflow. Both sieves can be adjusted electrically via CEBIS. This means that you can react quickly to changing harvesting conditions without having to leave the cab.

The GRAINMETER analyses the returns.

Using two sensors at the end of the lower sieve, the GRAINMETER registers the grains in the returns. Measurement of the returns by means of the photo cell makes it possible to calculate the proportion of grains to the total volume in the returns. The sensitivity is set in CEBIS where you can also read off the data conveniently and optimise the combine settings, if necessary.

The returns flow evenly into the threshing unit.

The returns are deposited on the accelerator drum, spread out and fed evenly to the threshing drum. At 15 l/s, the feed rate of the returns is a perfect match for the increased throughput of the new LEXION.

The returns volume is measured electronically.

A photo cell on the returns elevator measures the entire volume of material and reduces the operator's workload by means of the continuous display of the returns figure in CEBIS.

The operator monitors the returns from their seat.

The cab is designed in such a way that the operator can look straight into the illuminated returns section from their seat and so draw conclusions about the optimal machine settings..

Grain tank unloading at up to 180 l/s.

At 180 l/s you can unload the large grain tank of the LEXION in record time. The rate can be reduced from 180 l/s to 90 l/s. If necessary, you can stop the process immediately or turn off the augers gradually in order to completely empty the grain tank unloading tube first.

• Reliable filling of the transport vehicles
• No losses during unloading

Grain elevator with 59 l/s.

In view of the high throughput, the feed rate of the grain elevator has been increased to 59 l/s. The integrated moisture meter takes samples straight from the elevator and returns them once the measurement has been performed.

Precise yield measurement.

The new measuring principle used by the QUANTIMETER no longer requires the hectolitre weight for calibration. It determines the yield quickly and precisely by means of a baffle plate with an integrated measuring cell at the ejection point of the grain elevator. This system can be calibrated from the cab.

Fast crop inspection.

The port for manual inspection of the crop is situated in the cab access area. Even when the content of the grain tank is low, there is sufficient crop available here to allow you to take the first samples as soon as you start threshing.

Precise GRAIN QUALITY CAMERA.

The GRAIN QUALITY CAMERA provides real-time pictures of the crop. As the software identifies non-grain constituents and broken grains, you can use CEBIS to monitor the grain quality and assess it digitally at any time.

New features that make grain collection easier:

• Grain tank volume of up to 13,500 l enables extended harvesting runs
• Unloading rates of up to 180 l/s reduce the time taken to empty the tank
• Access to the grain tank is convenient and safe
• 105° pivot angle improves the view of the grain tank unloading tube
• The effort required to calibrate the QUANTIMETER has been reduced significantly; calibration is possible without leaving the cab

In addition to straw chopper drives with a manually adjustable chopper speed, there is also a version with hydraulic speed adjustment which can be controlled conveniently from the operator's seat. This option comes into its own when you have to work frequently in changing crop types. During swathing, a neutral setting saves fuel and reduces wear.

Technology that makes your straw management efficient:

• SPECIAL CUT with up to 88 knives
• Hydraulic or mechanical adjustment of the static knife array to three positions
• Switchover to swathing from the cab

Convenient spreader plate adjustment.

The extended straw chopping floor accelerates the chopped material and improves its spreading characteristics significantly. The new spreader plates are designed for a greater spreading distance. You can set the spreader plate angle, spreading width and direction conveniently in CEBIS. The impressive interplay of all these components delivers outstanding distribution of chopped material up to and including a cutterbar width of 7.7 m.

Precise power spreader.

The power spreader from CLAAS is synonymous with precise straw spreading – even with high volumes of straw, strong crosswinds or sloping terrain. Comprising two discharge rotors turning in opposite directions at a constant speed, it takes both the chopped material and the chaff straight from the cleaning section, accelerates it further and spreads it evenly across the entire working width.

Automatic discharge direction adjustment.

You can equip your LEXION with two sensors which automatically adjust the discharge direction of the chopped material to the terrain conditions. The sensors are fitted on the light brackets at the rear of the machine and ensure that the power spreader and deflector spread the chopped material evenly on slopes or in the event of crosswind. You set the sensitivity of this system in CEBIS.

Targeted chaff spreading.

During swathing, the chaff blower automatically turns outwards. Swaths of long straw and chaff/broken straw mixture are laid separately. For straw spreading, however, the chaff blower forces the sieve pan discharge straight into the power spreader for active distribution. Long straw, chaff and short straw are spread across the entire working width.
