Sixty

Over hundred years ago – just outside of Oakland, California – a legend was born. On June 24th, 1919, C.L. Best, who would go on to be Caterpillar’s first chairman of the board introduced the Best 60 Tracklayer. It was to become not only the best-known of Best’s Track-Type Tractors but was also the largest tractor of its era.

Renamed the Caterpillar Sixty after the merger between Best and Benjamin Holt, this machine was met with huge approval in the marketplace, and its innovations in engineering can be found in the DNA of today’s lineup of Caterpillar Dozers. 

The Caterpillar Sixty is a 60 horsepower (45 kW) Track-Type Tractor manufactured by the Caterpillar Tractor Company from 1925 until 1931. The Sixty was the largest tractor in Caterpillar's product line at that time.  Between 1919 and 1931, 18,948 C. L. Best 60 Tracklayer /Caterpillar Sixty Track-Type Tractors were manufactured.
