Diesel Machinery

What Diesel Machinery does

Diesel Machinery, Inc. (DMI) is a family-owned, authorized multi-brand construction equipment dealer serving South Dakota and adjacent portions of Southwest Minnesota, Northwest Iowa, and Eastern Wyoming from three dealership locations: Sioux Falls (headquarters), Rapid City, and Aberdeen. The company sells new and used construction equipment from more than 30 manufacturer lines, including Komatsu, JCB, Takeuchi, BOMAG, Dynapac, Sandvik, Doosan, Grove, and Epiroc, covering excavators, dozers, wheel loaders, skid steers, cranes, compactors, pavers, and aggregate processing equipment. Beyond equipment sales, DMI operates a short- and long-term rental fleet, a genuine OEM parts department, certified maintenance and 24/7 emergency field service, and equipment financing through partnerships with Komatsu Financial and regional banks.

The company's business model is a vertically integrated dealership model with six revenue streams: one-time new-equipment sales, one-time used-equipment sales, usage-based rentals, parts sales, professional service and repair, and managed financing. Pricing is quote-based and not publicly disclosed. GTM is enterprise field sales executed through territory managers stationed at each dealership, supplemented by inside sales via phone, email, and online inquiry forms, plus a Facebook/Twitter/LinkedIn presence and an iOS mobile app. The technology stack is primarily vendor-supplied: DMI supports Komatsu's MyKomatsu cloud-based fleet management platform (with KOMTRAX telemetry for GPS, fault codes, and engine diagnostics) and Topcon GPS fleet tracking, alongside its own inventory management and website listings.

DMI traces its roots back to the J.L. Healy Construction Company (incorporated 1932); the equipment dealership was formed in 1982 by Pat Healy, and the construction company was divested in 1989 as the dealership developed. Dan Healy, Pat's son, now serves as President, with General Manager Griffan Callahan supporting operations. The company is privately held by the Healy family with no external institutional investors or parent company, and operates exclusively within a regional Midwest footprint.
