1930-1940
In prewar times, production of the tractor began due to the need for agricultural development. During the war, mechanization of construction was in high demand at places like airports. However, it was the birth of bulldozers that truly started the history of construction equipment in Japan.
Based on a military order to make a bulldozer for maintaining the air base, Komatsu produced a trial sample in March 1943 using the drawing of a tractor for roads that had been completed in September 1942.
Originally it was developed for high speed running rather than a real bulldozer. 80 units were produced for a period of two years.

Since its first emergence in 1951, it took only 50 years for the hydraulic shovel to establish its primary position on construction sites worldwide. Its size ranges from mini to super size depending on the scale of construction, and during the half century, it kept evolving by achieving a minimum rear-swing radius and adapting styles that would work with characteristics of each site. Mirroring the movement of a human hand, a hydraulic shovel will continue to evolve during the 21st century.
