The CAT 20 Exp is the newest addition to the Heidrick Ag Center tractor family                                         

Built in 1927 the Caterpillar Expo Twenty Tractor was uses as show piece at county and state fairs or other local events. This versatile machine was commonly used in agricultural applications, but also in road building, hauling airplanes, and other tough jobs. 

The CAT 20 Expo is owned by the Veerkamp family of Placerville, Calif. Collectors of antique tractors, the Veerkamps began the process of restoring the Expo Twenty in 2007. As they researched the machine, the owners discovered that the inaugural tractor had not been painted with the standard gray and red color scheme, which was typical of Cat products built in the late 1920s. Instead, it had received a unique white paint job featuring black trim with brass- and nickel-plated accents. The Veerkamps not only returned the tractor to its original appearance, but also restored its original purpose. Having come full circle from its days as a show machine, the Expo Twenty is back in the public eye.

On June 13th the Ag History Center unveils new technology that encourages you to dial your cell phone and learn about new scholarship researched and written by  Ed and Sue Claessen.  Their book  Making Tracks, the story of the Best and Holt collection, won first prize in the category of both biography and history at the Midwest Independent Publishers Association.  They will be at the June 13 to tell you more about their story and explore the culture of agriculture. 

 Nineteenth-century observers watched in awe as cumbersome steam tractors and giant combines worked their way across vast fields.  In the twentieth century, California farmers led the nation in the adoption of gasoline tractors, mechanical pickers, harvesters and dozens of well-known machines.  

We invite you to experience the story of agricultural mechanization in California as seen through the collection and visiting exhibitions.  Also joining Ed and Sue Claessen are guest story tellers Doug and Matt Veerkamp who will expand on the Caterpillar story.
