Engine and running gear.

More power reserves. The engines.

The facts.

  • LEXION 670: Perkins 2206 D, 12.5 l
  • LEXION 650: Perkins 1506 D, 8.8 l
  • Six-cylinder in-line layout
  • Emissions standard Stage IIIA (Tier 3)
  • Full CLAAS Service integration
  • Fuel tank with 800 l capacity
  • High torque
  • Low fuel consumption
  • Optimal power transmission
  • Good accessibility for maintenance and care tasks.

    The engine platform can be reached easily via the access ladder. The radiator package can be folded up for cleaning. It is also possible to remove the air filter without tools. As a result, daily engine maintenance can be performed quickly. Service lighting on the ladder, the tank filling point and under the engine cover allows maintenance tasks to be carried out safely at night, too.

  • Planar dust extraction.

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

  • Fresh air.

    The air filter is easily accessible at the rear of the engine compartment. It can be removed easily for cleaning.

More ground protection in the field. TERRA TRAC.

Thoroughly proven in practical use.

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

At home on any road.

Today's traffic conditions make it increasingly difficult to transport large machines on public roads. What's more, the permitted width of vehicles transported on public roads is limited by national road traffic regulations. A total of three different TERRA TRAC tracks in three widths are available for the LEXION 670. 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 bodywork and mechanical components, increases operator comfort and ensures better stability on corners.

  • Automatic level compensation. Hydropneumatic suspension.
    • The hydropneumatic suspension can be raised or lowered during operation by filling or emptying the hydraulic rams
    • The drive wheel, land wheel and support rollers are counter-directionally pivot-mounted; hydraulic rams with an integrated pressure reservoir support the suspension
    • This results in automatic levelling at speeds above 2 km/h for improved stability on corners
  • At a glance: the TERRA TRAC crawler track assembly.

    Protecting the soil and preventing compaction during harvesting means you won’t have to worry about crop losses in the future.

    • Transport width 3.49 m
    • Soil protection: 66% lower ground pressure 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 suited to road travel at 30 km/h

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

More speed on the road.

More time to work.

Every minute a combine harvester saves in road travel improves performance in the field. The LEXION 670 TT attains a top speed of 30 km/h on the road.

This means that your LEXION can travel from field to field quickly with a high level of driving safety, excellent comfort and outstanding directional stability. The system was recognised for these qualities in 2011, when it was awarded a silver SIMA Innovation Award. TERRA TRAC allows you to spend more time in the field and significantly increases results for the season. Better adaptation to ground contours, uniform stubble height, less equipment stress and 30% lower ground pressure peaks make a clear difference. After all, soil protection means greater profit.


Hydrostatic ground drive.

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 series of hydrostatic drives is characterised by increased efficiency. You benefit because the power saved is available for use by the rest of the machine, the overall result being greater efficiency in 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.
