LEXION 670-620

Power and intelligence in one.

The new Mercedes-Benz engines with a displacement of up to 10.7 l deliver top performance for the LEXION while keeping operating costs down. With these engines, all LEXION 600 models meet the requirements of exhaust emissions level Stage IV (Tier 4). The LEXION 670 and 660 models have a displacement of 10.7 l and are now also equipped with DYNAMIC COOLING.

The facts.

  • LEXION 670 / 660: Mercedes-Benz OM 470 LA, 10.7 l
  • LEXION 650 / 630 / 620: Mercedes-Benz OM 936 LA, 7.7 l
  • Six-cylinder in-line layout
  • Emissions standard Stage IV (Tier 4)
  • DYNAMIC COOLING for LEXION 670 / 660
  • New fuel tank with 800 l capacity
  • High torque
  • Low fuel consumption
  • Optimal power transmission

Planar dust extraction.

A reliable system: with planar dust extraction, the LEXION 650, 630 and 620 models benefit from high-performance cooling and comfortable reserves of cooling capacity. As air is being drawn in at the top, an automatic dust extraction system ensures continuous cleaning of the radiator. The dust is extracted downwards. Soiling of the cooling fins is reduced significantly.

The LEXION 670 and 660 models are now also equipped with the revolutionary, horizontal cooling system. Having proved itself comprehensively in the LEXION 700 over the past few years, it is now also being adopted in the LEXION 600 series. 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 an extremely useful curtain effect. The air flow actively inhibits dust from rising, thus preventing soiling of the radiator and effectively providing permanent cleaning. This has two advantages: appropriate cooling at all times and long maintenance intervals.

MONTANA. Higher performance on steep slopes.

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

Effective threshing just like on level ground.

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.

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.

LEXION 670 and 660 with TERRA TRAC.

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 three different TERRA TRAC tracks in three widths are available for the LEXION 670 and 660 models. This means that there is a suitable TERRA TRAC for every requirement.

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.

Hydrostatic ground drive.

The hydrostatic ground drive of the LEXION can be controlled extremely easily with the multifunction control lever without the need to operate a clutch or change gear. The new series of hydrostatic drives is characterised by increased efficiency. You benefit, as the power saved is available for use by the rest of the machine, the overall result being more efficient operation.

All models have an electrohydraulic control system and can also be equipped with the CRUISE PILOT for automatic forward travel control. But whether used in manual or automatic mode, the LEXION drives like a luxury car with such a high level of operating comfort that performance is enhanced immediately.
