Caterpillar D6 Model Bulldozer: Museum Object and Cultural History

The object in the museum catalogue

The nature of farming dramatically changed in the 20th century through what came to be known as the Green Revolution. From the 1920s-1950s farming productivity rose dramatically due to mechanization, fertilizers, chemicals (fungicides, pesticides, herbicides) and the hybridization of plants and animals. Agricultural innovations continue to be important to farming today. While the museum has over a dozen full-size tractors and other pieces of farming equipment, most technical developments of the 20th century are represented in the collection through toys and models.

The Ertl Company of Dyersville, Iowa, made this metal model of a Caterpillar D6 bulldozer during the 1960s. The tractor is Ertl stock number 301, and is built on a 1:16 scale.
