About the company
Diesel Machinery, Inc., a for-profit Subchapter S corporation headquartered in Sioux Falls, South Dakota, supplies heavy equipment repair, equipment sales, and related services to federal agencies as a prime contractor exclusively (100% of awards), competing predominantly in full-and-open procurements with no set-aside designations across its footprint except for one Buy Indian award to the Indian Health Service. The vendor operates across NAICS codes centered on earth-moving and excavating equipment manufacturing and maintenance (primary PSC Earth Moving And Excavating Equipment covering 30 of 52 awards) and commercial machinery repair and maintenance, with a cumulative federal award history spanning three decades and a recent combined potential value of $1.2 million.
Diesel Machinery's customer base is fragmented across eight distinct federal agencies with no dominant customer anchoring the portfolio. The Department of the Army Corps of Engineers Engineering District Omaha leads by combined potential value at $655 thousand across four awards, followed by the Department of Energy Western Area Power Administration at $281 thousand across six awards, and the Department of Health and Human Services Indian Health Service at $69 thousand for one award — these three account for 85% of combined potential value. The remaining five customers (Department of the Air Force Air National Guard, Department of Agriculture Forest Service R1-Northern Region, Department of the Interior Bureau of Indian Affairs and Indian Education, and others) each hold smaller shares. This concentration is shallow; the top five customers represent only 33% of award count, indicating a historically broad but thin customer engagement pattern.
Recent named work includes a $9.3 thousand definitive contract from the Department of the Interior's Great Plains Region for JCB backhoe repairs at the Cheyenne River Agency (awarded July 8, 2026, completed July 22, 2026); a $74.1 thousand purchase order from the Western Area Power Administration for AR Barko flail mower repair and Grove crane hydraulics (awarded November 9, 2023); a $57.2 thousand purchase order from Western Area Power Administration for Grove crane hydraulics repairs supporting Rapid City line crew operations (awarded September 14, 2023); and a $68.7 thousand purchase order from the Indian Health Service under Buy Indian authority for a 3TS-8W-HF skid steer for the McLaughlin IHS Health Center (awarded June 12, 2023). Award activity is sparse and episodic — one award in 2026, four in 2023, two in 2018, and one each in 2019 and 2015 — with only one award facing ultimate completion in the next twenty-four months ($9 thousand recompete exposure). The vendor does not serve on government-wide vehicles or BPAs and operates exclusively on definitive contracts and purchase orders. Diesel Machinery maintains no subcontracting footprint; all 52 awards are prime contracts.
