Waltanna manufactured large four-wheel drive tractors in southern Australia in the 1970s and 1980s. Waltanna was the product of James Nagorcka, a farmer in Victoria who built his first tractor on his farm in 1975. By the 1980s Waltanna was offering a range of tractors. Ford contracted with Waltanna to manufacture the Ford FW series four-wheel drive tractors in the mid 1980s. Changes in the market led Nagorcka to end tractor production in 1989 and focus on other ventures.
