When real-world requirements and experience are combined with the latest research findings, the result is a machine which impresses on every count. We've listened to you and have designed a machine that is tailored precisely to your needs. The new LEXION.

The facts.

  • Mercedes-Benz OM 473 LA, 15.6 l (LEXION 780 / 770)
  • Perkins 2206F, 12.5 l (LEXION 760)
  • Mercedes-Benz OM 470 LA, 10.7 l (LEXION 750 / 740)
  • Emissions standard Stage IV (Tier 4)
  • Optimised combustion process


  • Improved engine running characteristics
  • High torque
  • Low fuel consumption
  • Optimal power transmission

Stage IV (Tier 4) through SCR and EGR.

All LEXION 700 models comply with the Stage IV (Tier 4) emissions standard by means of SCR (Selective Catalytic Reduction). This process converts the nitrogen oxides in the exhaust flow into pure nitrogen and water. The urea solution necessary for this is carried in an 80-litre tank. In addition, EGR (Exhaust Gas Recirculation) is used to mix a proportion of the engine exhaust gas with the intake air. This reduces the combustion temperature in the engine which in turn largely prevents the formation of nitrogen oxides.

DYNAMIC COOLING.

Now for all LEXION 700 models.

All LEXION 700 models are equipped with a revolutionary, horizontal cooling system. It is optimally situated in a horizontal position behind the engine compartment. A large rotating sieve with a diameter of 1.6 metres ensures that it is able to take in sufficient fresh air at all times. Permanent cleaning is performed by an automatic dust extraction system. The large radiator package has sufficient reserves to ensure continuous cooling while also providing the benefit of extended cleaning intervals.

Save fuel through variable fan drive.

Unique among combine harvesters, all LEXION models are equipped with a variable fan drive whose speed is adjusted automatically in accordance with the degree of cooling required. This makes it possible to save power which the rest of the machine can call on. This intelligent system only draws power when it really requires it.

It's curtains for heat build-up.

The design of the cooling system provides an ideal air flow. Air is drawn in at the top, passes downwards through the radiator and is then vented through the engine compartment and side cooling fins.

This creates a particularly useful curtain effect. The air flow actively inhibits dust from rising, thus preventing soiling of the radiator and effectively functioning as a permanent cleaning system. This has two advantages for you: sufficient cooling at all times and long maintenance intervals.

More performance on steep slopes. LEXION 760 / 750 MONTANA.

The drive axle is the key component of the LEXION MONTANA. Hydraulic swing rams turn the portals to adjust the wheels to the ground. The MONTANA chassis compensates cross tilt up to 17% and longitudinal tilt up to 6%. As a result, it is able to operate effectively on steep terrain and deliver a high threshing output, just like on level ground. The operator is in an optimal, comfortable seated position on any slope, enabling even long working days to be handled without stress.

The advantages of MONTANA at a glance:

  • Side slope levelling up to 17%
  • Longitudinal levelling up to 6%
  • Suitable for cutterbars up to 9 metres wide
  • Improved traction thanks to a differential lock
  • Easier operation
  • Improved functionality of the entire MONTANA control system thanks to working hydraulics
  • 30 km/h hydrostatic ground drive
  • Car-like driving characteristics
  • More comfort for the operator
  • Same performance as on level fields

The working hydraulics: more lifting power, faster response.

The outstanding performance of the LEXION is now better then ever on steep slopes too. New working hydraulics offer improved operation of the entire MONTANA control system.

  • Higher efficiency of the working hydraulics thanks to an axial variable displacement pump (LS pump)
  • Operating pressure 200 bar (+10%)
  • Oil displacement of the working pump: 120 l/min (+50%)
  • Greater front attachment lift capacity: +10% weight / +50% faster response (proportional valve technology)
  • Maximum reversing power even when idling, 10% more torque
  • Synthetic oil with a high viscosity index provides better friction characteristics
  • Low noise thanks to constant system pressure
  • Efficient pump distributor gear

NEW: LEXION 750 can now also travel at 40 km/h.

In addition to the LEXION 760, the LEXION 750 is now available as a 40 km/h version. The maximum speed can be attained with the three different track widths of the TERRA TRAC system. The combination with the 635 mm wide TERRA TRAC is ideal for machines with a high proportion of on-road travel. With an external width of 3.29 m and a 40 km/h top speed with reduced engine revs, your on-road travel is safe and efficient.

30" tyres up to 1.65 m high.

The greater contact area results in a reduced track depth. So you are protecting the ground not only with TERRA TRAC at the front, but with the unique CLAAS 30" tyres on the rear wheels.

  • Tyre size 500/85 R 30
  • Tyre height up to 1.65 m
