A Crucial Step In The Evolution Of Modern Animal Agriculture Was The Development Of Mechanical Ventilation Methods For Animal Housing. Air Inlets Are Pivotal To Good Ventilation. In 1948 William F. Millier, Working At Cornell University Under The Direction Of Professor Clesson Turner, Tested And Published The Concept Of The Slotted Inlet. Professor Turner And Others At Cornell University Subsequently Continued To Develop Slotted Inlet Systems And Systematize Design Methods.

Brothers Cyril and Louis Keller designed and built the first small, lightweight, three-wheel, front-end loader in their machinist-blacksmith shop in Rothsay, Minnesota. A local farmer wanted to mechanize cleaning manure from his obstacle-filled, two-story turkey barn. The machine, first used in 1957, was able to turn completely around within its own length. Melroe Manufacturing Company, Gwinner, ND purchased the rights to the Keller loader and hired the Kellers to continue development of the loader in 1958.

In 1850, E. W. Quincy of Illinois patented an open-roll ear-snapping mechanism. A series of innovations led to corn heads for combines. Harvesting corn with corn pickers using open rolls on corn pickers after 1925 proved to be dangerous as farmers often needed to clear stalks from the rolls. In 1885, E. M. Aiken, Dawson, ND, patented shielded snapping rolls with flat plates above the rolls. C. K Shedd and E. V. Collins, Ames, IA, patented a more aggressive shielded snapping device in 1941 which was later used on sweet corn pickers.

In 1941, near Palouse, Washington, Raymond A. Hanson conceived of a self-leveling mechanism for hillside combines. On the steep hills in the Pacific Northwest, leveling is necessary to save grain because of the gravity grain separation mechanism. Before the Hanson invention, manual leveling required a person to stand on the combine platform and adjust the machine to the lay of the land - a hot, tedious job. The grain-saving attributes of Hanson's invention were probably more important than the labor saving, although both were valuable.

The Rumely Companies, which operated in La Porte, Indiana, from 1853 to 1931, produced a variety of equipment including threshers and steam engines, which helped to change the nature of American and world agriculture. The revolutionary OilPull Tractor, which was introduced in 1910, used a unique carburetion system developed by John Secor, the Company's Chief Engineer. The OilPull tractor efficiently converted a low cost petroleum product to mechanical power, greatly reducing the need for animal and steam power on American farms. Dr.

Early tractors were massive and expensive. Their steel lug wheels gave poor traction and a rough ride. Lugs were prohibited on many roads. 1926 Hoyle Pounds modified a Fordson tractor with zero pressure truck tires on special rims to improve performance on sandy soils in Winter Garden, FL.
A successful business resulted. In 1929 Hessel Roorda equipped Farmall tractors with low pressure rubber tires to pick corn in muddy fields near Rock Valley, IA. Farmers found they performed well in all conditions.

The Rain Bird horizontal action impact drive sprinkler head was invented in 1933 by Orton Englehardt, a citrus grower and native of Glendora. The design offered slow rotation and uniform watering, benefits long sought by local irrigators. Clement M. LaFetra, a friend of Englehardt, urged early patent application. A patent was awarded on December 18, 1933. Englehardt, with no entrepreneurial aspirations, assigned all rights to LaFetra and his wife Mary Elizabeth. Production began in the LaFetra family barn on October 13, 1935.
