Quality harvesting without constraints.

LEXION 6000 / 5000.

The APS SYNFLOW WALKER threshing system is gentle on the straw as a result of a particularly straight crop flow. This design means that the crop takes the shortest path through the threshing unit. The large diameter of the threshing and separator drums enables small contact angles and flat transitions between the drums. The outlet of the separator concave is larger than its inlet. The increasing width of the gap prevents the crop from building up and causing congestion. There is hardly any mechanical stress on the straw.

You have many possibilities for optimising the LEXION to meet the characteristics of your farm and your fields so precisely that your campaign performance increases to a significant degree.

• DYNAMIC POWER adjusts the engine output to the power requirement. This allows you to achieve fuel savings of up to 10%.
• DYNAMIC COOLING reduces your diesel costs. The variable fan drive adjusts its speed automatically in line with the degree of cooling required.
• TERRA TRAC reduces soil compaction. The crawler track units offer a high level of driving comfort and are narrow enough for road travel.
• You can harvest on slopes as effectively as on level ground. The LEXION 5500 is also available as a MONTANA version.
• The differential lock on the front axle allows you to continue to operate reliably in difficult terrain.
• For greater tractive power in difficult terrain you can equip your machine with a POWER TRAC 4-wheel drive.

DYNAMIC POWER automatically adjusts the engine output of your LEXION to the operating conditions. This means that you are always running with the most efficient power curve when operating under partial load and can save – during swathing, for example – up to 10% of fuel. At full load when the grain tank is being unloaded and the straw chopper is engaged, for example, maximum engine output is automatically maintained.

DYNAMIC POWER uses a variety of power curves on the basis of the engine load. The parameter which triggers the power adjustment is the reduction or increase in the engine speed resulting from a change in the power requirement.

What makes DYNAMIC COOLING so unique?

• Variable fan drive provides cooling when required
• Provides effective and reliable cooling
• Uses full fan speed only under full load
• Minimises extent to which dust is able to rise
• Reduces soiling of the radiator and engine compartment
• With grain tank unloading tube extended, automatically increases speed to actively blow dust away from engine compartment
• Extends the air filter maintenance intervals

All LEXION models are equipped with a 2-speed hydrostatic ground drive with convenient gear selection via the buttons on the armrest. The high efficiency of the hydrostatic motor saves power which is available to the rest of the machine. Both the wheeled machines and the TERRA TRAC models can travel at up to 40 km/h.

The secondary separation via the straw walkers is accomplished over a total length of 3,800 mm across four straw walker steps. Even large volumes of straw are transported rapidly and loosely.

• Large separation area for precise secondary separation
• Centre and side risers to fluff material
• Maintenance-free, robust straw walker bearings.

The JET STREAM cleaning system with its hydraulic fan speed variator and high-performance returns has plenty of performance capacity in reserve in all crop types. A dual-ventilated step enables intensive pre-cleaning. JET STREAM is controlled conveniently from the cab. You no longer have to adjust anything manually. As an option, you can put the JET STREAM cleaning function under the fully automatic control of CEMOS AUTO CLEANING.

With a volume of up to 13,500 litres, the grain tank has a capacity to match the huge throughput of the LEXION.

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.

Even when the machine is operating in strong crosswinds, handling high straw volumes or negotiating side slopes, the power spreader always deposits the straw precisely. 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.

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. The chopped straw and the sieve pan discharge are spread across the entire working width.

The LEXION 5500 MONTANA is the ideal combine harvester if your farm is located in a hilly region. With 4-wheel drive and differential lock, it is perfectly at home in particularly challenging terrain and is able to operate successfully even under extreme conditions.

With its fully automatic side slope compensation of up to 18% and longitudinal compensation of up to 6%, the LEXION 5500 MONTANA is able to cope with even the hilliest of fields. Efficient cutting on slopes is ensured by the MONTANA feeder housing with precise MULTI CONTOUR cutterbar guidance.

CEMOS AUTOMATIC is a self-learning operator assistance system which provides you and your operators with continuous, active support throughout the entire work process. On the basis of harvesting parameters, such as grain quality, threshing quality, standard of cleaning, straw quality and throughput, the system checks sensors and settings. It optimises your LEXION to its technical performance limits while it is running.

The functions at a glance:

• CEMOS DIALOG guides the operator to the best machine settings
• AUTO CROP FLOW protects the entire system against overload
• AUTO SLOPE controls the fan setting on the basis of the slope
• CRUISE PILOT actively controls the harvesting speed
• AUTO CLEANING improves cleaning by controlling the sieve opening and fan speed
• AUTO THRESHING provides fully automatic adjustment of the threshing concave clearance and the threshing drum speed
• AUTO HEADER actively controls the position of the reel and the VARIO cutterbar table
• AUTO CHOPPING improves the chopped material quality and reduces fuel consumption

Controlled through CEBIS, the CEMOS DIALOG operator assistance system guides you to the optimal machine setup. Settings which are confirmed by you are implemented directly by CEMOS DIALOG. You are motivated to check the settings more frequently and also benefit from the learning effects.

The machine always keeps you informed about the scope for optimisation. It continuously indicates all the factors imposing the greatest limitations on throughput and actively suggests ways to increase performance.

Harvest right up to the grain loss limit.

• You only have to calibrate the loss sensors at the start of the day.
• CEMOS DIALOG actively supports you with loss measurements.
• After the loss level has been changed, the sensitivity of the sensors is corrected automatically.
• The machine always works precisely up to the limit set for acceptable losses.

Steering systems are an essential tool in your everyday work. The LEXION can be equipped with three automatic steering systems, which you can choose between on the basis of the task in question: the digital AUTO PILOT, the satellite-based GPS PILOT CEMIS 1200 and the electro-optical LASER PILOT, which we can also equip with the FIELD SCANNER for you as an option.

• With Machine connect, you transmit data from the machine straight to the cloud.
• With CEMIS 1200, you create and manage all jobs on the spot in the machine.
• With DataConnect, you are able to process the data from your machines, regardless of manufacturer.
• With Machine connect, you are able to simplify maintenance and service activities.

A drive system that has what it takes:

• Hydraulically actuated dry clutch
• Hydraulically tensioned main belts
• Standardised belt tensioners
• Improved power transmission
• Lower maintenance costs

Like all its predecessors, the LEXION is also appreciated for being a model of restraint where maintenance requirements are concerned. The maintenance intervals are long: 1,000 hours for the oil in the working hydraulics. Daily maintenance tasks can be carried out quickly and effortlessly. All the key maintenance points can be accessed easily.

The robust engine compartment cover makes it particularly easy for you to access the grain tank and to perform any maintenance tasks required there. It is slip-resistant and designed to be walked on. Handrails and a folding step provide additional safety.

• All the maintenance points around the machine are easily accessible.
• Contact points for the mobile ladders enable safe access for maintenance and cleaning tasks.
• The side panels, steps and engine compartment are brightly lit.

All components subject to particularly heavy wear and tear in the crop flow are optionally available in PREMIUM LINE quality. These are the right choice when you have to harvest under extreme conditions which are particularly hard on your combine harvester. PREMIUM LINE components are extra resistant to wear and corrosion and have a very long service life. Even with intensive annual use or when subjected to aggressive crops, these parts will not usually have to be changed until after several campaigns. This increased durability is achieved through special manufacturing processes, high-quality materials and special coatings.
