Wisconsin Potato and Vegetable Growers Association
Interview with Jim Mortenson
What started out as a truck and tire business turned into one of the largest potato and vegetable operations in the state of Wisconsin.
This unusual turn of events is the story of Mortenson Brothers Farms, Inc., a 10,000-acre potato and vegetable farm headquartered in Plainfield, Wisconsin.
Brothers Gary (“Jack”) and James (“Frog”) Mortenson were in the trucking and tire business in Antigo, Wisconsin — Mortenson Brothers Trucking and
Southside Tire. They had hauled potatoes for a farm that could not pay them back, so they took on ownership of part of the crop. Jack left Antigo that summer to watch over their new potato investment.
