Wintersteiger Seedmech LLC

Wintersteiger Seedmech LLC, a small business based in Elkhart, Iowa, manufactures specialized agricultural research equipment for the USDA Agricultural Research Service as a prime contractor under total small business set-asides and full-and-open competitions. The vendor operates exclusively in prime capacity across three recent awards totaling $822 thousand, all with the Department of Agriculture, competing without SBA designation leverage beyond its small business status.

Wintersteiger's capability portfolio centers on high-precision crop research equipment spanning two product lines. The vendor manufactures plot combines — specialized harvesters with adjustable threshing systems, hydrostatic drives, and cutting widths optimized for cereals, peas, soybeans, sunflower, and sorghum — and cone-regulated seeders with electric drive systems, GNSS calibration, and variable rate seeding for high-throughput planting trials. The vendor also integrates near infrared spectrophotometer systems into plot combines to measure seed protein content and quality traits in-line during harvest. Representative work includes a $460,865 total small business definitive contract awarded in September 2025 for a cone-regulated seeder and plot combine harvester to support crop variety evaluation and agronomic research at the Charlotte, Vermont research station; a $264,143 purchase order for a Wintersteiger Plot Combine with one-year warranty and certified technician service, delivered to the Dale Bumpers National Rice Research Center in Stuttgart, Arkansas (awarded May 2026, performance through May 2027); and a $97,038 purchase order for a near infrared spectrophotometer system with thermoelectrically cooled InGaAs photodiode array detector and integration into the Wintersteiger Quantum Plot Combine Harvest Master data collection system (awarded September 2026, completed December 2026 at East Lansing, Michigan).

Customer concentration is entirely with USDA Agricultural Research Service across its three subordinate operational areas. Two awards totaling $361 thousand reach ultimate completion inside the next twenty-four months, representing near-term recompete exposure. The vendor has no identified subcontract footprint or parent contract vehicle participation in the available source data.
