Cotta has designed and manufactured speed reducers in the US for over 100 years.  Cotta speed reducers match the optimum engine speed to the optimum driven equipment speed, allowing your engine and load to both operate at ideal efficiency.  Typical uses include pumps, dredges, compressors, crushers, drills, and high-performance machinery for oil and gas, construction, mining, and other industrial applications.  The gearboxes are heavy-duty and are designed for use with diesel engines, electric motors, PTO’s, and other prime movers.
