The Outdoor Power Equipment Institute (OPEI) is the major international trade association representing the manufacturers and their suppliers of consumer and commercial outdoor power equipment such as lawnmowers, garden tractors, utility vehicles, trimmers, edgers, chain saws, snow throwers, tillers, leaf blowers and other related products. Founded in 1952, the Institute is dedicated to promoting the outdoor power equipment industry by undertaking activities that can be pursued more effectively by an association than by individual companies. -- from the OPEI Web site
