The Antique Caterpillar Machinery Owners Club

Preserving the legend behind the name

One of the most recognizable names in the world is Caterpillar. Whether it’s their machinery or licensed products, Caterpillar represents quality and longevity.

In the early 1990’s, some folks from Oregon decided to turn their enthusiasm for Cat machines, specifically their legendary line, into a formal club seeking others with the same passion. Little did they know their “yellow blood,” an affectionately used term to describe those with a passion for Caterpillar, runs deep.

From this, the Antique Caterpillar Machinery Owners Club (ACMOC) was born. Now an international organization with thousands of members, ACMOC strives to assist and educate its members and the general public to appreciate the historic role of Caterpillar machinery in shaping the world. ACMOC further promotes the collection, preservation, restoration, display and study of products and memorabilia of Caterpillar and its related predecessors.

ACMOC publishes a bi-monthly full-color magazine filled with feature stories on the historical role of Cat machines, restoration tips and updates on member projects. ACMOC also hosts a website,, filled with similar features plus a bulletin board that gives users instant access to others where they can ask restoration questions, brag about their recent find, and share photos.

ACMOC enthusiasts not only like to fix up vintage Caterpillar machines, many still use them in their operations or to simply enjoy a good day of playing in the dirt.  ACMOC members participate in several shows around the world where they display their machinery, tackle major mounds of earth – often seeking out local projects to assist with - and get together and share camaraderie with those who share their passion.
