Coinciding with the introduction of its latest Lexion 700 series combines, Claas has developed Cemos Automatic, the world’s first system that has the ability to continuously monitor and automatically adjust a combine’s settings to match the harvest conditions.
Cemos Automatic, which is a development of the Cemos (Claas Electronic Machine Optimisation System) system first introduced in 2010, will be an option on all new Lexion 700 series models from 2013. The original Cemos system helped to improve combine harvesting performance by guiding the operator to the optimal machine settings through adjustment suggestions.
Until now the operator had to actively request the suggestions and accept or reject them, but with Cemos Automatic, the system allows the combine to adjust the separation and cleaning settings automatically and without operator input.
When used in combination with the GPS Pilot automatic steering system and Cruise Pilot throughput controller, this means that the Lexion combine can operate virtually automatically, maintaining optimum performance in the areas of throughput, grain quality, grain cleanliness, minimal fuel consumption and ease of operation.
The new Cemos Automatic system uses numerous sensors to monitor a wide variety of the parameters of the combine harvester with split-second accuracy; it will immediately adjust the settings to match current conditions.
Cemos Auto Separation optimises residual grain separation by adjusting the parameters for rotor speed and concave position. Cemos Auto Cleaning, meanwhile, regulates the cleaning process via the parameters for blower speed as well as upper sieve and lower sieve opening.

Cemos Automatic is based on the familiar Cemos system and the automatic variant retains the same dialogue function. The automatic functions are displayed on the Cebis terminal. These are always activated when the combine leaves the factory, but can be shut off by accessing Cebis Mobile. Furthermore, Cemos Auto Separation and Cemos Auto Cleaning can be switched on and off separately.
In Cemos Automatic, the operator can choose between four optimisation strategies: maximum throughput (if the harvesting window is very tight or if the weather conditions are favourable); minimum fuel consumption; high threshing quality; and balanced (combining the three other possible settings). On initial preproduction machines, using the maximum throughput operating strategy in Cemos Automatic resulted in combine output improvements of up to 20 per cent.
“Without regularly checking and optimising the machine settings, we wouldn’t have been able to break the combine harvesting world record last year,” Claascombine harvester specialist Jens Broer said. “During the 20-hour endurance test, we remained in contact with Cemos, and as a result adjusted the machine settings to the prevailing harvesting conditions.
“However, during day-to-day farm operation it’s often the case that the operator only makes minor or very few adjustments to the system out of a fear of making mistakes.”
