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.
This metal model of an International Harvester grain drill was made by the Ertl Company of Dyersville, Iowa during the 1970s. The grain drill could be attached to the International Harvester tractor models made by Ertl.
