The Nelson name has been tied to manufacturing and irrigation products for over 100 years. It all started when Lewen Russell Nelson invented the “Clincher” hose coupler and opened Central Brass and Stamping Company in Peoria, Illinois in 1911. This company later became L.R. Nelson Mfg. Co. Inc., which ultimately was sold in 1972. Nelson Irrigation was founded at the time of the sale and in the nearly four decades since, NIC has led the agricultural irrigation industry with innovations such as Big Gun® Sprinklers, Rotator® Sprinklers, 3000 Series Pivot Products, 800 Series Control Valves and a complete line of Pressure Regulators
