Clark Equipment Company

[1] The company moved to Buchanan, Michigan in 1904 when that city's chamber of commerce advertised a financially sound deal with respect to industrial rent and power supply.

[1] Eugene B. Clark, an Illinois Steel employee at the time, determined that the metallurgy of Rich Manufacturing's principal product, a railroad rail drill named the Celfor Drill, was faulty, and also found fault with both the management and basic operations, which he ultimately corrected after the two parties established him becoming an equal partner.

In 1935–1936, Clark built a one-of-a-kind aluminum body trolley for a PCC streetcar that ran in Brooklyn and Queens, New York, until 1956.

[7] In 1954, Clark Equipment opened a plant in Valinhos, Brazil, to produce gears and truck transmissions for the South American Market.
