CPS – CLAAS POWER SYSTEMS.

Optimal drive for best results.

The CLAAS machinery development programme constantly strives to maximise efficiency, improve reliability and optimise cost-effectiveness. CLAAS POWER SYSTEMS (CPS) bring together top-quality components to create a drive system that sets new standards – and always delivers maximum power when it is needed. CPS is ideally matched to the working system, featuring fuel-saving technology that quickly pays for itself.

Performance packaged.

Strong at heart.

A 6-cylinder, 8.7 l FPT (Fiat Power Train) Cursor 9 engine gets to work under a one-piece bonnet. The engine meets the requirements of the Stage IIIB (Tier 4i) emissions standard by means of exhaust aftertreatment with urea, and uses the latest common rail 4-valve technology, charge-air cooling and a wastegate turbocharger.

Visctronic – economical fan control.

With Visctronic electronic fan control the fan speed can be precisely aligned with engine temperature and load, directly linked to the engine ECU, ensuring that the engine always runs at the optimum temperature. The reduced fan speed lowers the noise level and saves valuable fuel with no unnecessary impact on output, which can then be converted into tractive power.

Constant output.

The CLAAS-specific engine performance curve provides full torque in a wide engine speed range, guaranteeing constant output and power delivery when they are needed. This makes it easy to save fuel while working at a low engine speed and maximum torque with the ECO PTO, or to work at rated speed with a full reserve.

Greatest pollutant reduction of all time.

Fully integrated SCR system.

There is no doubt that the introduction of the Stage IIIB (Tier4i) emission regulations is the most important step to date in the control of pollutant emissions. These regulations require a 90% reduction in particulate matter (PM) as well as a 50% cut in nitrogen oxide(NO

) content. The

implementation of Stage IV (Tier 4) by 2015 will bring a further reduction in PM and(NO

) emissions to almost zero.

SCR – the urea-based solution.

SCR stands for selective catalytic reduction, a process in which nitrogen oxides are converted into water and pure nitrogen. This is achieved by using a synthetic aqueous solution of urea (AdBlue tank.

),which is carried in an additional

When designing the AXION 900, all the components required for exhaust aftertreatment were considered from the outset. This means that full visibility and accessibility are guaranteed. The SCR catalytic converter is safely housed under the bonnet where it receives a constant flow of cooling air.

Never lets you down.

For particularly cold conditions, a cold-start system is available to heat the engine cooling water, battery, fuel filter and SCR system. The urea tank is heated as standard and is also protected from the cold by the insulating effect of being integrated into the fuel tank. The SCR system lines are also emptied automatically when the engine is switched off to protect against freezing.

AdBlue® is a registered trade mark of the VDA.

CMATIC is the name of the continuously variable transmission technology used in CLAAS tractors. In the AXION 900 series a ZF Eccom transmission provides efficient conversion of engine power. In this split-power, continuously variable transmission, the four mechanical ranges areautomaticallyselected by multidisc clutches. There is no need to shift between ranges manually.

km/h

The high mechanical component of the CMATIC transmissionprovides outstanding efficiency and low fuel consumption in every speed range.

For instance, when working in the field at between 7 and 15km/h in the main operating range, the CMATIC transmission averages over 80% mechanical power transmission, far superior to other continuously variable transmissions on the market.

And for transport operations on the road, the CMATIC transmission will be averaging a 90% mechanical situation, a clear advantage in terms of fuel consumption.

km/h

Exploiting real potential.

At speeds of 0.05 km/h to 50 km/h, the full power of the transmission can be used in either direction because power is transmitted mechanically even in reverse. What's more, every gear ratio can be used at every engine speed. The AXION 900 therefore offers enormous potential for use all year round.

With engine speeds of 1,600 rpm at a top speed of 50km/h and 1,500 rpm at 40km/h, the AXION 900 also demonstrates its capabilities in transport operations.

If the accelerator is not depressed, the transmission is in powered zero mode and maintains its position without creeping or rolling. This means that the tractor can start up safely and easily at steep field entrances or road junctions, even with a full load.

CMATIC

Simple, straightforward operation.

The CMATIC transmission has three operating modes: AUTO (foot pedal), CMOTION (hand control)and manual mode. Forward speed can be controlled by the accelerator pedal or CMOTION. In these two modes, engine speed and transmission ratio are adjusted automatically – for optimum efficiency and optimised fuel consumption.

Accelerator pedal or CMOTION.

A button in the armrest enables the driver to switch between modes while the tractor is moving. However, manual mode can only be activated in CEBIS. In manual mode, the driver chooses the engine speed and transmission ratio. Automatic engine and transmission control is not active. The active mode at any given time is displayed on the CEBIS.

Optimised settings.

At the push of a button.

The engine speed at full load can be adjusted quickly and easily using the engine droop settings. The CEBIS clearly displays your set engine loading. When a constant engine speed is activated, i.e. during PTO work, the driver can specify a different droop setting, typically one that retains the engine speed to the required PTO shaft speed.

The engine droop can be specified separately for the individual drive modes and both engine speed memories. The engine droop can therefore be tailored to the application in hand at the push of a button, e.g. when moving from the road to the field when transporting slurry. The CMATIC transmission technology from CLAAS enables you to use all 400 hp economically and productively.

CMATIC

No need to stop.

Tailor-made speed ranges.

With theCMATICtransmission, three speed ranges can be pre-selected in both directions of travel. The active range is displayed on the CEBIS and can be changed while the tractor is in motion using the two buttons on the CMOTION multifunction control lever.

The lower the maximum preset value for the range, the more accurately the forward speed can be controlled. Cruise control speeds can be saved in all three ranges while the tractor is moving, either in CEBIS or using the button on the CMOTION.

With CMATIC every driver can create his own profile according to the job in hand. Intelligent CMATIC transmission technology enables you to use all 400hp economically and productively – with maximum operator comfort.

Stopping power.

The CMATIC transmission offers different ways of adapting braking to the job in hand:

• Increase the engine braking effect: when the accelerator pedal is released and the CMOTION is pulled back,the engine braking effect is intensified and break wear is reduced

• Driving down an extremely steep hillside with a heavy trailer: by pressing the CMOTION when the trailer brakes are on, you can tension the brakes on the tractor/trailer combination when starting from stationary on hills. This function can be used at speeds of up to 10 km/h.

CMATIC

Real stability. The true sign of a 400 hp tractor.

CLAAS has drawn on experience gained in developing standard tractors and XERION high-horsepower tractors delivering up to more than 500 hp to create a completely new solution for the AXION 900 – for endurance work under extremely challenging conditions. The engine is housed in a strong frame section with an integrated engine oil sump which perfectly absorbs all the forces associated with the front linkage and front axle carrier. In practice, this means:

• Excellent steering lock angle for maximum manoeuvrability

• Optimum access to the entire engine compartment and all maintenance points

• High ground clearance with drive shaft integrated into the frame section with a bolted cover for protection

• All services securely routed within the frame section

CLAAS tractor concept. 400 hp – for real.

Long wheelbase – compact design

To transfer 400 hp to the ground, the design must be just right. The AXION 900 ticks all the boxes. It has a wheelbase of 3.15 m, but its outstanding design makes it manoeuvrable in the field and easy to drive on the road. And naturally, its overall length with an implement attached remains within the legal limits.

Additional front ballast is not needed for many tasks – particularly transport operations – as the long wheelbase and optimum weight distribution transfer the tractor's tractive power to the ground. This saves fuel and reduces tyre wear on the road.

Construction

Immense tractive power.

Fully balanced.

With so many front and rear axle ballast options, the AXION 900 is easily adapted to every application. This is the only way of exploiting its full performance potential without unnecessary losses.
