Tuff Torq Corporation was incorporated on July 1, 1989, and is a subsidiary of the Kanzaki Kokyukoki Manufacturing Company Limited and the Yanmar Co. LTD.. Tuff Torq manufactures transmissions and transaxles for the Lawn and Garden power equipment industry. We are located in the Morristown, Tennessee on the rim of the Smoky Mountains. Tuff Torq has over 200,000 square feet of manufacturing space. Kanzaki built state-of-the-art production facility brings high automation, and strict precision quality control to the manufacturing of Tuff Torq products. In addition, this advanced technology allows Tuff Torq to operate at maximum levels of capacity with minimum labor intensity. Tuff Torq also operates in a nontraditional manner. There is no reserved parking, and all employees wear uniforms. These policies reduce the "totem pole"​ effect that exists in traditional manufacturing companies. As a result Tuff Torq has low turnover and absenteeism. The Tuff Torq Brand is growing in consumer awareness. A recent national independent consumer report shows that nine out of the top ten lawn and garden tractors are powered by a Tuff Torq drive system. From more than sixty years of innovation based on trusted design engineering and manufacturing, Tuff Torq designs drive systems that emphasize the power and performance. Even as a component manufacturer, we listen to what consumers want from their applications. We find what consumers are saying through focus groups, outdoor power equipment demonstrations at retailers like Home Depot and Lowes. By listening to end users we can respond to our customers'​ needs that exceed expectations. Tuff Torq has also manufactured and sold more than 750,000 performance driven marine transmissions worldwide. Founded upon Japanese quality and lasting value, Tuff Torq transmissions are designed to perform in the most demanding applications offering more torque capacity and less weight.
