An Iowa man has collection of 60 unique pump jacks, including a walking beam pump jack.
The Kuhlman pump jack is rare: Owner Don Hahn says he knows of just 11 or 12 others. The unique design makes it a crowd pleaser at shows. "It’s just fun to watch it run," he says.
The Kuhlman pump jack has no markings or casting numbers. Don Hahn had new shafts put in about four years ago. "It was starting to show some wear," he says.
This walking beam pump jack, dating to about 1900, tells a little-known chapter of a company later famous for its tractor. Letters at the top of the beam reveal the manufacturer, Waterloo Gasoline Engine Co. The unit is powered by a Beats ’em All gas engine.
