The University of Nebraska Tractor Test Laboratory is the officially designated tractor testing station for the United States and tests tractors according to the codes of the Organization for Economic Co-operation and Development (OECD). Twenty-nine countries adhere to the tractor test codes (including non-OECD members: China, India, the Russian Federation, and Serbia), with active tractor test stations in approximately 25 of those countries. The OECD codes require that tractors be tested in the country of manufacture. Reciprocity agreements with the codes require that once an OECD test report is officially approved, it must be accepted by all participating countries.
