This Caterpillar Thirty tractor sits next to a Caterpillar Sixty tractor. A nearby placard highlights the Caterpillars and tells us:
Mighty Cat Sixty
"In 1925, the Holt Manufacturing Co. and the C. L. Best Traction Co. merged, forming the Caterpillar Tractor Co., Peoria, Ill. The rest, as they say, is history."
Ground-covering Innovation
The Caterpillar Tractor Company hit paydirt in 1930 with its "Cat Sixty," a gasoline-powered machine producing the force of sixty horses.
Weighing 21,000 pounds with massive, endless treads, this crawler tractor proved ideal for building logging roads and pulling log wagons, high wheels, and other equipment. The widely used Cat Sixty was the forerunner of today's bulldozers; the continuous tread technology it used was also the basis for military tanks.
