The Antique Caterpillar Machinery Owners Club (ACMOC) was founded in 1991 by a small group of enthusiasts who all shared a similar passion, the legacy of antique Caterpillar machinery. At the time, they had no idea that their club would one day grow to have thousands of members all around the world.

Now based in Peoria, Illinois, ACMOC's mission is to assist and educate its members, and the general public, to appreciate the historic role of Caterpillar machinery in shaping the world. ACMOC promotes the collection, preservation, restoration, display, and study of products and memorabilia of Caterpillar and its related predecessors.

Whether you own antique Caterpillar machinery, or simply have an interest in the history behind it, ACMOC offers something for everyone. Through our full-color magazine, shows, local chapters, and bulletin board, members enjoy the camaraderie of shared interests.
