Denning

In the dawn of the twentieth century, Denning crafted tractors within the heartland city of Cedar Rapids, Iowa. Beginning as the Estherville Fence Factory in 1893, established by J.M. Denning, the enterprise relocated to Cedar Rapids in 1899. By 1912, the company transitioned away from fence production, divesting its machinery and patents to become the Denning Motor Implement Company. Ultimately, in 1918, the General Ordnance Company acquired Denning, ushering in a new era and a renaming to National Tractor.
