More power reserves. The engines.

Power and intelligence in one.

The new Mercedes-Benz engines with a displacement of up to 15.6 l deliver top performance for the LEXION while keeping operating costs down. With the new Mercedes-Benz engines, all LEXION 700 models meet the requirements of exhaust emissions level Stage IV (Tier 4). With a displacement of 15.6 l, the two top models, the LEXION 780 and 770, have copious reserves of power. In the case of the LEXION 780, in fact, a maximum output of 626 hp is available. The LEXION 750 and 740 models have a displacement of 10.7 l and are now also equipped with DYNAMIC COOLING. Only the LEXION 760 is powered by a Perkins engine, which, like all the others, benefits from the full range of CLAAS Service support.

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 / 2016

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
LEXION 780-740

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

TERRA TRAC. More ground protection in the field.

CLAAS has offered its proprietary TERRA TRAC system for over 20 years and there are now countless TERRA TRAC drives in use around the world. The CLAAS TERRA TRAC has proven itself in practical use in the most challenging conditions time and time again.

At home on any road.

Today's traffic conditions are making it increasingly difficult to transport large machines on public roads. What's more, the authorised width of vehicles transported on public roads is restricted by the respective road traffic regulations of each country.

A total of four different TERRA TRAC tracks in three widths are available for the various LEXION models. This means that there is a suitable TERRA TRAC for every requirement.

A TERRA TRAC Rice with a drive width of 890 mm is available for the LEXION 770 and 760. The LEXION 760 also attains a road speed of up to 40 km/h with this drive.

A new dimension of comfort.

Your LEXION moves gently over the field on the sophisticated TERRA TRAC system which features independent suspension for all its components (drive wheel, land wheel and support rollers). This reduces shocks to the body and machinery, increases operator comfort and ensures better stability on corners.

Three different chassis heights can be set in CEBIS to adjust the machine's ground clearance.

LEXION 780-740

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.

TERRA TRAC suspension / 2013

At a glance:

  • Transport width only 3.29 m (LEXION 760 / 750)
  • Transport width 3.49 m (LEXION 780 / 770)
  • Ground protection: 66% less pressure on the soil than with wheeled machines
  • Improved traction (maize/rice/wet conditions/slopes)
  • Greater stability on slopes (side slopes)
  • Less drive resistance, less slippage, lower fuel consumption
  • Longer operating times, better seasonal performance
  • Fully suitable for road travel at 30 or 40 km/h

LEXION 4-link axle / 2013

More manoeuvrability. The 4-link axle.

LEXION – a commitment: to the active pursuit of new solutions. This design, developed and patented by CLAAS, sets new standards with two outstanding advantages. It ensures unrestricted mobility, even with large tyres up to 1.65 metres high (30"). And it provides exceptionally high stability and load-bearing capability.

Rather than responding to uneven terrain like a conventional swing axle with just a swing motion about the suspension point, the new 4-link axle also features a lateral movement. This gives the 4-link axle considerably greater flexibility with a small turning radius.

LEXION 780-740

Unique 30" tyres for excellent ground protection

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

Tyre pressure adjustment system for steering axle.

In order to provide even greater traction, the steering axle of the LEXION 780 – 740 can be equipped with a tyre pressure adjustment system. The operator can then easily adjust the tyre pressure from the cab via CEBIS. If the required tyre pressures for road and field use have been stored, the appropriate setting is applied automatically when the on-road switch is actuated. As an alternative to using CEBIS, the tyre pressure can also be adjusted manually in the field by means of a toggle switch mounted in the cab roof.

Lowering the tyre pressure in the field reduces ground compression and slip while increasing traction. Adjusting the pressure for on-road operation increases directional stability while reducing wear and fuel consumption.
