Brothers Cyril and Louis Keller designed and built the first small, lightweight, three-wheel, front-end loader in their machinist-blacksmith shop in Rothsay, Minnesota. A local farmer wanted to mechanize cleaning manure from his obstacle-filled, two-story turkey barn. The machine, first used in 1957, was able to turn completely around within its own length. Melroe Manufacturing Company, Gwinner, ND purchased the rights to the Keller loader and hired the Kellers to continue development of the loader in 1958.

The Northern Pacific High Line Bridge No. 64, built between 1907 and 1908, has continued to perform yeoman service in the uninterrupted flow of the Nation's commerce. Nearly, 100 years after this bridge officially opened, it still carries 125-ton car unit coal trains, double stack container trains, lumber, and refined products at train speeds of 50 m.p.h.
