  Valmont® Industries  

 

 

Frank Zyback, part-time farmer and part-tinkerer, had hammered together the prototype center pivot in 1947 after viewing a demonstration of hand-moved pipe. During the next several years, he continually modified and refined the basic design to improve its operational efficiency and, in 1954, agreed to license his patent to Bob Daugherty, who eight years earlier began Valley® Manufacturing (now known as Valmont® Industries).

Valmont®'s engineers took Zyback's unit apart and rebuilt it again and again over the next several years to make it sturdier, taller, and more reliable. By the early 1960s, according to Daugherty, Valmont had overcome most of the design and production problems. A basic improvement was conversion from the original water hydraulic power system to electric drive. Most machines were running on electric power by 1975.

Valmont® introduced corner systems in 1975 to assist in irrigation of square, rectangular, and other odd shaped fields.

Valmont® currently operates from 31 facilities located in eleven countries around the world. The Company is headquartered in Omaha, Nebraska.
