The full engine power that is available on a high-performance harvester is only exploited to the full when there is a good supply and constant flow of grass, maize or wholecrop silage into the machine.
For example, only 500-600hp is needed when harvesting wilted silage. Running the engine at full power when this is not required by the work at hand needlessly increases fuel consumption.
The answer, according to Claas, is their new Cemos Auto Performance to match engine output to the work at hand, by altering the power curve.
In the field, the operator starts the assistance system, and selects an engine speed, a forward speed, and one out of 10 engine-power curves. After the autopilot is started, the forager and the tractor-trailer combination start working.
The preset engine speed is accepted directly by the forager and is maintained by the automatic control system.
When the preset power output is too high for the crop being harvested, the system automatically switches to a lower and more efficient output range while maintaining the current forward speed and engine speed.
Vice versa, the system switches to a higher output range when harvesting higher-yielding stands.
The automatic engine output control eases the strain on both the forager and driver in a very convenient way, and leads to environment-friendly fuel savings of up to 15%.
Cemos Auto Performance won one of the 39 silver awards for innovation at Agritechnica, the world’s leading trade fair for agricultural technology, which took place from November 10-16 in Hanover, Germany.
