The track-type tractor (also known as the crawler dozer) was developed by American Benjamin Holt in 1904. It is a dozer that is equipped with a human-controlled lift in front of a crawler tractor. The power at the time was a steam engine, and then a track-type tractor driven by a natural gas-powered and gasoline-powered machine was developed. The dozer blade has also been developed from manpower to wire rope lifting.

Benjamin Holt is also one of the founders of Caterpillar Inc. in the United States. In 1925, Holt Manufacturing merged with C.L and Best Bulldozers to form Caterpillar Bulldozers, becoming the world's first manufacturer of earth-moving equipment. In 1931, it successfully rolled out the first 60-type bulldozers with diesel engines.

With the continuous advancement of technology, the current bulldozer power has all adopted diesel engines, and the bulldozer blades and ripper are all upgraded by hydraulic cylinders.
