Proven efficiency in the field In trials conducted by the DLG in Germany, CEMOS for Tractors was shown to reduce fuel consumption by 16.8% in addition to a 16.3% increase in efficiency. For the trials which were conducted on a large farm in Saxony-Anhalt, the DLG brought together ten experienced drivers from Germany, France, Poland and Denmark. Here they were joined by test engineers from the DLG Test Centre to measure the ground speed and fuel consumption of all the test variants. For the tests, using two AXION 870 CMATIC tractors the operators carried out both shallow- and deep-cultivations on the test plots over a three-day period. In the first part of the test the operators, who in many cases had done initial research on the optimum setting, used their own initial settings for the front ballast, wheel weights, tyre pressure and engine droop and then continued to adjust these while working without using CEMOS for Tractors. Each of the tractors was supplied with a selection of different ballast weights and was fitted with the integrated CLAAS CTIC 2800 tyre pressure control system. Having completed all the runs using their own settings, all the test drives were repeated, but with CEMOS for Tractors activated. This time the drivers confirmed the suggestions for optimisation that they judged to be appropriate or requested alternative suggestions from CEMOS for Tractors. As indicated by CEMOS, ballast weights were replaced, tyre pressure was adjusted and engine droop changed as necessary. This process also continued until the optimum performance for the test plots and the prevailing conditions was reached.
HIGHER AREA OUTPUT WITH REDUCED DIESEL CONSUMPTION Having completed the test drives, the recorded values for all the drivers with and without CEMOS were analysed and evaluated at the DLG Test Centre and averaged to give an overall rating. The results: CEMOS went way beyond the mere effect of a tyre pressure control system: it was able to reduce diesel consumption by up to 16.8 percent and at the same time increase the area output by up to 16.3 percent for 80 percent of the operators. Taking these fuel consumption figures over 3000 operating hours of cultivation, a large tractor with a diesel consumption rate of 50 l/h without CEMOS for Tractors and 41.6 l/h with it could save up to 25,200 l of diesel and 67,000 kg CO2! In addition, by increasingly area output, the hours worked by the farmer or contractor are reduced by up to 490, which is equivalent to almost 50 working days.
