About Us

Though we have a wide range of industries our brands cover, our beginnings lie in the agriculture industry. Terra Drive Systems, Inc. is home to Mud Hog, the world's toughest breed of steerable hydraulic drive axles for combines, which was established in 1976 in Brookston, IN -- the place we still call home. In April 2000, TDS became ISO 9001 certified and remains committed to producing quality materials that are built to last, holding an ISO 9001:2015 certification today.

In early 2008, we combined our knowledge and experience base of Mud Hog agriculture systems to introduce EZ Trac, North America's first hydraulic front-wheel-drive assist axle for medium to heavy-duty trucks. To date, we have over 1,000 axles on the ground, moving fleets forward.
