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, even with the front attachment fitted. 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.

Straight-line crop flow saves fuel.

Large drum diameters and small contact angles enable particularly flat transitions between the threshing and feeder drums as well as the rotors. This means that there is a straight, fuel-saving crop flow through the combine harvester. What's more, there are no unnecessary changes of speed or direction of flow. This makes for gentle straw handling and saves fuel.

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.
• 600 mm feeder drum - Blockage-free feeding of the harvested material to the rotors.
• Hydraulic threshing concave flap - 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 10%.

We have revolutionised the threshing system of the new LEXION from the ground up. The combination of the tangential APS SYNFLOW threshing unit and the axial ROTO PLUS secondary separation makes the APS SYNFLOW HYBRID threshing unit the trendsetter for its class. You can look forward to 10% higher throughput during your next harvest – with extremely low fuel consumption and top straw quality.

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:

• A 57% larger feeder drum ensures that no blockages occur as the harvested material is transferred to the rotors
• Up to four divided hydraulic rotor flaps are fitted ex factory and prepared for incline-dependent control
• The finger rotor concaves are self-cleaning and wear-resistant
• Together, all these features increase the separation performance, even under difficult harvesting conditions

Hydraulic rotor flap adjustment.

You can adjust the secondary separation area as required in CEBIS. Hydraulic rotor flaps close up to four rotor segments while the machine is on the move.

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 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.

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

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.

Grain tank unloading tube with 105° pivot angle.

In order to improve your view of the grain tank unloading tube, the pivot angle has been increased from 101° to 105°. You can select the length in accordance with the width of the front attachment. The diameter depends on the desired unloading rate: 420 mm for 180 l/s or 330 mm for 80 to 130 l/s.

Grain tank unloading tube 7XL.

The 7XL grain tank unloading tube makes it possible to use the CTF (Controlled Traffic Farming) principle to protect the soil while working. The transport vehicle can follow 12 m away in the track which the combine harvester made during the previous pass.

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.

Grain elevator with 80 l/s.

In view of the high throughput, the feed rate of the grain elevator has been increased to 80 l/s. The integrated moisture meter takes samples straight from the elevator and returns them once the measurement has been performed.

Technology that makes your straw management efficient:

• SPECIAL CUT with up to 108 knives
• Hydraulic or mechanical adjustment of the static knife array to three positions
• Switchover to swathing from the cab

Three straw chopper drives.

In addition to two 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.

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.

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.

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.
