Cotta Transmissions and Gearboxes…A Driving Force for More Than a Century

1906 — While Henry Ford’s innovative, moving automobile assembly line was revolutionizing manufacturing methods, engineer Charles Cotta established the Cotta Transmission Company. He introduced his own breakthrough: the constant-mesh shifting transmission; soon Cotta supplied the emerging automobile and truck industries with main transmissions.

1940s — Cotta began a shift to industrial products and the off-highway and construction specialty vehicle markets.

Mid 1960s — Cotta added a line of high-speed transmissions (the now well-known “SN” line).

Over the years, Cotta diversified into various products including hydraulic pumps and coal augers.

Today – Cotta (with production facilities in Beloit, Wisconsin) is a trusted, leading manufacturer of top-quality, precision-engineered transmissions for a wide range of specialized mobile and stationary applications: vocational trucks, defense, off-highway, aerospace, heavy industry, well-drilling, mining, marine and more.
