Why it’s great
The machine that gave Caterpillar its name didn't start on a construction site. It started in a California wheat field in 1904, when Benjamin Holt replaced his steam tractor's wheels with wooden tracks and changed heavy equipment history forever. This first definitive scholarly biography traces Holt's life and inventive genius — from his refinements to the combined harvester to his patented crawler tractor, the direct ancestor of every bulldozer, excavator, and tracked machine working on job sites around the world today.
