Caterpillar Fifteen Tractor

Vrain Conley recently donated his restored Caterpillar Fifteen tractor to the Roots collection in Willits. Construction Number PV2353, the Cat 15 was built about 1930, and spent most of its working life in the Healdsburg area of Sonoma County. The tractor joins our Cat Ten, Cat Thirty, our two Cat Sixtys, and our D-8 2U in the “Caterpillar Collection.”
