In the 1980's, Danfoss (formerly Sauer-Danfoss) in Ames, IA, produced a hydraulic transmission that was paired with an axle assembly at the OEM.

Agri-Fab in Sullivan, IL, produced an axle assembly that was paired with a transmission at the OEM.

Hydro-Gear was founded in 1991 as a joint venture. The initial goal was assembling the transmission and axle combination prior to supplying the OEM. What has resulted is a passion for innovation, new product integration, and growth at our customers.

Today, Hydro-Gear is a world leader in the design and production of precision drive solutions, serving multiple industries and exporting product worldwide.
