CMATIC transmission. Continuously variable for real performance.

Efficient and easy to use.
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.
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.

Exploiting real potential.
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.
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.
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, e.g. during PTO work, the driver can specify a different droop setting, typically one that matches 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.

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.
