Sudenga Industries, Inc.

What Sudenga Industries, Inc. does

Sudenga Industries, Inc. is a privately held American manufacturer of grain, feed, and seed handling equipment, founded in 1888 by German immigrant Folkert Sudenga as George, Iowa's first blacksmith shop and continuously operating from the same northwest Iowa site for over 135 years. The company designs, engineers, and manufactures its products in-house, with a portfolio spanning three categories: grain handling equipment (portable augers such as the HOSS and TD-450, stationary augers, bucket elevators, chain conveyors including the Loop Conveyor System, bin unloads and sweeps including the Double Barrel Power Sweep, drive-over hoppers, truck and railcar hoppers, and specialty augers); feed processing equipment (roller mills, hammer mills including the Liberator II and Double Hammer Mill Skid, micro ingredient systems, horizontal mixers, loss-in-weight systems, feed batching skids, and the CBX desktop-PC batching software); and seed handling equipment (BOS seed box opening systems, tubular and horizontal belt conveyors, bulk seed loadout tanks, and undercar belt hoppers). Product throughput ranges from utility-scale augers to high-capacity systems such as the 20,000 BPH Ultra Scoop and the 36-48 TPH RGS-2020 roller mill.

The company's go-to-market is exclusively through an authorized dealer network spanning the United States, Canada, and selected international markets via partners such as Ag Builders, R&D Equipment Company, and Southern AgCom; Sudenga does not sell directly to end customers. Pricing is quote-based and not publicly disclosed, with revenue generated primarily from hardware sales of equipment plus a recurring stream of replacement parts, flighting, shafts, and accessories sourced through the same dealer channel. Sudenga serves five customer segments: farm operations, commercial agriculture operations, feed processing operations, seed handling operations, and industrial material handling operations. Notable enterprise customers include Hoffman Grain Services (operating since 1994 across a seven-state area using an Ultra Scoop purchased in 2007 that has moved over 143 million bushels), Farmer's Choice Feed in Kirksey KY, and Farmer's Elevator in Clara City MN. The 2026 AE50 Award from ASABE for the patent-pending Double Barrel Power Sweep is the most recent external validation of ongoing R&D investment.

Sudenga is a subsidiary of Diversified Technologies, Inc. (DTI), a locally owned Iowa conglomerate that also owns the Dur-A-Lift aerial lift business; DTI is one of Lyon County's largest employers with 200+ staff. The company has remained under local ownership since its founding with no evidence of external private equity or venture capital investment, and recently expanded its George, Iowa manufacturing facility with climate-controlled production space to support headcount growth.
