for nearly 100 years twin disc has been developing, engineering, manufacturing and distributing power transmission products that make things work. they are seldom seen, but they go into machines that contribute to the standard of our lives. twin disc products are installed in the drivelines and powertrains of farm tractors, road pavers, cranes, mining trucks, oil rigs, logging equipment, firefighting and rescue vehicles, pleasure craft, fishing and work boats, pumps, turbines - you name it. they manage and control the horsepower generated by internal combustion engines and electric motors. they help feed us, provide natural resources, build our cities and homes, transport us, defend us and influence our lives daily in many unnoticed but critical ways. where there's an industrial strength vehicle or machine that requires converting horsepower to productivity, twin disc has a way to do it. so, in a very real sense, twin disc has helped put the world to work, for nearly a century.
