You may know us as Martin, Martin Brothers, or Martin Sullivan, but whatever you know us as, you know you can count on the Martin name for the very best equipment and service in Illinois. In 2021, to celebrate our 95th year in business, we’ve decided to go back to our roots and rebrand the business from Martin Sullivan to Martin. You’ll see a new logo on the website and a new sign out front, but you’ll see the same faces and quality John Deere equipment at each of our locations.
