Task Force on Mechanical Coupling for Agricultural Vehicles (TFAC)
Reports to R55

This task force was established in May 2013 to pursue the update of UN Regulation No. 55 on mechanical couplings as it concerns agricultural vehicles. During 2008-2011, a group of German experts from KBA, technical services and manufacturers developed a proposal for a new regulation covering this subject. Therefore, the Informal Group on UN Regulation 55 decided to use this earlier proposal as a starting point of the task force’s work.
