Holt crawler tractor at Chena Hot Springs
Here is a Holt 5-ton tractor, probably dating from about 1924. Holt Manufacturing is credited with developing the first practical crawler-type tractor in 1904. The company named its creation the "Caterpillar" tractor. Holt merged with Best Gas Traction Company in 1925 to form Caterpillar.
