Jeff Wahl’s love of old iron was bred into him early. When he was 3 years old, he already owned a gasoline engine, courtesy of his grandpa Harvey Wahl, a 1-3/4 HP Associated Chore Boy that he still owns today.

Jeff’s father, Tom Wahl, had moved the family to Fairfax Station, Va., but the family returned to Grandpa’s Minnesota farm for a week or two each summer, around the time of the Butterfield (Minn.) Threshing Bee. “So I’d get to see my grandparents and the rest of the family that lives in the Minneapolis-St. Paul area,” Jeff says. “We would all attend the Butterfield show to help Grandpa show his antique farm equipment, camp out and have a family reunion of sorts.

“For me, going out to the farm, as we did every summer, was a completely different world from northern Virginia, a suburb of Washington, D.C.” Jeff says. “I enjoyed being on the farm, riding Grandpa’s farm machinery, helping to mow the lawn and pick veggies from the garden. And best of all, I got to see all my aunts, uncles and cousins.

“When we were young, we would jump off the hay wagons into the piles of threshed hay and get dirty and filthy,” he laughs. Additionally, he remembers riding in the parade on the back of an Aultman-Taylor 30-60 tractor that Grandpa operated for the elderly owner at the Butterfield Threshing Bee, “getting a ride, sitting on back with my legs hanging off. My parents say I used to spin my arms in a circle like a flywheel going around and made the sounds of an engine, shoo shoo shoo put,” he says. “It was a fun experience.”

Rare gasoline engines 

The Wahl family has a series of rare gasoline engines about which little is known:

1904 9 HP Flour City 

Harvey Wahl bought this rare item Sept. 14, 1974, at an estate auction in Valley Springs, S.D. “The engine was complete, including the original water tank, but it had been completely taken apart because it was in the process of being restored,” Jeff says.
