Energy classification of used tractors ; Classification énergétique des tracteurs d'occasion

Ce numéro de la revue Innovations Agronomiques est dédié aux articles issus des programmes Casdar 2008-2010 ; National audience ; During the Grenelle of the environment, reduction of energy dependence of farms was posted as a major issue. To meet the objectives of the Plan of Energy Performance, a consortium of partners fromthe technological joint network based on the energy in agricultural engineering (www.agroequipementenergie.fr), accompanied by the Ministry of Agriculture and the ADEME has sought to develop anenergy classification of tractors. The purpose of the classification was to provide new criteria of choice, related to the energy consumption of the tractors to farmers to direct their investments in new or usedtractors, corresponding to their needs and work. The classification has been produced in relying on the results of all of the performances measurement to the bench tests carried out by the operators of mobile test bed (more than 3000 per year). Index CIBEM (Classification index bench of test engine) is characterizing the energy efficiency of the engine of the tractor. It is calculated by comparing the energy efficiency of the tractor to a reference related to the power of the tractor. It leads to a score (A to G), and repository based on the same principles as the classifications used for household appliances. For each tractor measured by the test bed, an energy label will be attached to the report of diagnosis. It should enable farmers to make choices of energetically more acceptable tractors. For farm advisors, it allows them to increase the relevance of theadvice given to farmers in the stages of renewal of tractors. Finally, the regular update of the classification database will make it possible to follow the changes of the state of the park of tractors. ; Lors du Grenelle de l'environnement, la réduction de la dépendance énergétique des exploitations a été affichée comme un enjeu majeur.
