Preserving the machines that built California.

From horse-drawn ploughs to steam-driven giants and the fuel-powered workhorses of modern agriculture — every gallery winds visitors through a chapter of the state's story.

The California Agriculture Museum is home to the nation's most unique collection of tractors and artifacts. Interactive exhibits and special events tell the history of farm to fork, dating back to the Gold Rush era.

Hear local storytellers boast of how California food producers did things bigger and better — through harvesters, wheel and crawler track-type tractors, combines, trucks, and a sweeping art and photo gallery.

Help Us Continue

We house the rarest collection of tractors in the world — and we're determined to share it with the community and future generations.

Three threads, one extraordinary story.

From rare iron giants to interactive farm-to-fork exhibits, the museum offers something for every visitor — whether you're a school group, a researcher, or a curious traveler.
