It's been more than 50 years since turkey farmer Eddie Velo dropped by to sulk inside the Keller brothers' blacksmith shop in Rothsay, Minn.
Velo's farmhands had done it again. Quit. Right before it was time to shovel 12 inches of turkey dung out of five two- story barns.
Velo's dilemma got brothers Cyril (Cy) and Louis Keller thinking. It wasn't long before they surprised Velo with a sketch of an innovative two-wheel-drive contraption that they thought just might scoop dung and navigate a barn's narrow corners like a champ.
Six weeks later, the first Bobcat skid-steer loader was born. It wasn't long before the Kellers' blacksmithing days of sharpening plows and building farm trailers were behind them. They built six loaders, including one with an extra-strong manure fork, fashioned from the bars of the Rothsay jail.
Lester Melroe of Melroe Manufacturing -- a North Dakota ag equipment firm that employed the brothers' uncle -- invited the brothers to demonstrate their Keller Self-Propelled Loader at the 1958 Minnesota State Fair.
The crowds grew so big "we didn't have room to operate," said Cyril, 86.
"Melroe was really surprised. We had 100 people at a time trying to get up to see it. On our third day, here comes Melroe with a handful of [Melroe] stickers, putting them on our machine," recalled Louis, 85. "We were there to sell our machine to him. So we thought, 'This was pretty good.'"
Fast-forward 50 years, and the business partnership struck that day has turned into an international hit. This week, the Keller brothers celebrated the 50th anniversary of their Bobcat invention as the company made its 750,000th loader in Gwinner, N.D. (In 1969, Melroe sold to Clark Equipment Co., which became part of Ingersoll Rand in 1995.)
