About Caterpillar
Caterpillar Tractor Company was formed in 1925 by combining Holt and C. L. Best. Its agricultural crawler heritage later led to Challenger rubber-track tractors, a business sold to AGCO in 2002.
- Beginning
- 1925 merger
- Founder / origin
- Holt Manufacturing and C. L. Best Tractor Company
- Known for
- Tracked machinery and industrial equipment
- Sale / later history
- Challenger agricultural tractor business sold to AGCO in 2002
History and legacy
The original product range combined machines from both predecessor companies. Farm use remained important early on, but construction became central as wheeled farm tractors spread. The Challenger sale concerned an agricultural business, not the closure of Caterpillar.

Index power values can include estimates derived from belt or PTO power. They are identified on each model card and are not interchangeable with a measured engine rating. Model years and missing values follow the source index.
