Deeply Rooted

The GSI Group, LLC has roots dating back to the 1930’s. As thehistory1 Great Depression loomed over the country, agriculture played an important role in the recovery. The Sloan family, realizing a need for reliable and affordable farming equipment, began providing farmers throughout the Midwest with the latest grain production equipment and innovations. Over the years, second and third geerations of the Sloan family expanded on the family business to encompass a variety of agriculture related products and services to meet the ever growing need for quality production equipment.
