Twin Disc Inc.

Racine,, WI, United StatesUpdated Sep 2003

For over three-quarters of a century, Twin Disc has designed, built and distributed a family of critical performance products that influence the development and prosperity of our world. They are installed in the drivelines and power trains of off-highway equipment. They manage and control the horsepower generated by electric motors and internal combustion engines. They are seldom seen, but they go into machines that contribute to the standard of our lives. They're found in fishing boats, work boats and pleasure craft, farm tractors, irrigation pumps, crash-fire-rescue vehicles, mining equipment, oil field, construction, logging and railway equipment, just to name a few. They help feed us, build roads, cities and homes, provide natural resources, transport us, defend us and influence our lives daily in many unnoticed but critical ways. The company has grown in product offerings and is ISO 9001 certified, with global manufacturing in three world sectors and worldwide distribution capabilities. And for a company with such unique products to have led power management for over 75 years, its leaders had to know how to seize its moments as well as anticipate the future. Today Twin Disc continues to meet the challenges through high velocity development of new problem solving products that meet the needs of emerging new markets. From a farm tractor near Racine over 75 years ago, to a contemporary crash-fire-rescue vehicle at an airbase in Belgium, Twin Disc has put horsepower to work for over three-quarters of a century. Our core values and customer focus provide the platform from which we make contributions to global markets and critical industries. That is our past. That is our future.
