History and use
This model Thirty was manufactured in 1928. This model would have originally been painted grey with red trim, the official livery of the Caterpillar Tractor company from 1925 to 1931. It is currently painted yellow with black trim, the official livery of the Caterpillar Tractor company from 1932 onwards. The tractor was sourced by Bert Thiess for his collection from a private individual in Caboolture, Queensland. It is not known if the repainting was done by Bert Thiess or if he purchased it in this condition.
This was one of the first crawler tractors produced by the newly founded Caterpillar Tractor company (1925) after the C.L. Best Tractor Company merged with the HOLT Manufacturing Company. This model was a rebadged version of the C.L. Best model 30 that had been manufactured by the C.L. Best Tractor Company since 1921.The Thirty was a popular tractor in the marketplace as it was tough and reliable and was therefore chosen to become one of the first Catepillar offerings. The Caterpillar Thirty was manufactured from 1925 to 1932 and there were approximately 23,830 made in total.
