Community Engagement Certification reveals the value of local museums to their community

     The Heidrick Ag Museum and Event Center is proud to announce the completion of their Community Engagement Museum Assessment Program certification by the American Alliance of Museums. This certificate validates the completion of an in depth review of the museum’s purpose, mission, history and significance in theMuseum Certificate community by a third party team of museum experts. Among the pages of findings, suggestions, and accolades was the realization that, although the non-profit center is listed as the number one attraction in Woodland, California, drawing more than 10,000 visitors annually from around the world, majority of the surrounding community members have yet to discover this local gem. Read more…

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.

A reliable source of water is an essential part of California farming.  In this year of extreme drought, many farmers have sought new sources of water to irrigate their crops.  Some farmers have also had to be flexible about which crops to plant, and when and how to irrigate them.

A century ago, California farmers often relied on water pumps and local wells for essential irrigation water. The Heidrick has two vintage water pumps on display in the East Wing dating to the early 20th century.  The 1921 Myers self-oiling “Bulldozer” water pump, powered by a Cushman gas engine, is a high capacity reciprocating pump, delivering water on both the up and down strokes.1  A 1907 Fairbanks Morse water pump and “vertical” T series gas-powered engine brought water to the Henry Morgue Ranch of Durham, California2.  

These pumps and motors, and other equipment essential to California agriculture, are on display at the Heidrick Ag History Center, Wed. – Sun. from 10:00 am to 5:00 pm.
