MAIN EXHIBITION ENTRANCE HISTORY OF JAPANESE BULLDOZER EXHIBITION
-

1930-1940 OPEN

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.

Komatsu Diesel tractor D35

While the size of tractors were getting bigger, research for use of diesel engines with heavy oil was proceeding. D35 was loaded with a diesel engine that employed a gasoline starter engine. This was the birth of Japan's first diesel tractor. 

A large order was expected due to the development plan in Manchuria, however, things did not go as originally planned and, after all, only seven units ended up working in Manchuria. 47 units were manufactured until the production was discontinued in 1942.

Weight: 4200kg

Bulldozer OPEN

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.
