A Caterpillar Expo Twenty Tractor built in 1927 was displayed at this year’s CONEXPO-CON/AGG.
This tractor has the distinction of being the first machine wholly designed and built by what was once called Caterpillar Tractor Co. Prior to producing the Expo Twenty, Caterpillar had been manufacturing track-type tractors using the assets and designs of its two predecessor companies, the C.L. Best Tractor Co. and The Holt Manufacturing Company. But when this unit rolled off the assembly line, it received an all-new serial number, EXP 0000-L, and earned a place in company history.
Its designation as an “EXP” or “expo” machine suggests it was either built for a special occasion or used by Cat dealers as a marketing tool at county and state fairs or other local events. The “L” in the serial number indicates it was manufactured in San Leandro, Calif.
