FARM COLLECTOR MAGAZINE STAFF

Farm Power magazine was introduced in 1935 by several men who had published The American Thresherman. The American Thresherman, a victim of the Great Depression, ceased publication in its 34th year in 1932. One interesting story they tell about the old magazine is the reaction of many of the steam traction engine manufacturers to the new-fangled gas tractor in 1903.

Lots of power was needed to pull big plows in order to break the vast tracts of tough prairie sod on the central and western plains of Canada and the United States. Steam traction engines were used for the task, but there were difficulties. Coal and wood fuel had to be hauled for long distances and, in many locales, water was scarce and alkaline. Under the hard plowing conditions that prevailed, steam boiler flues surrounded by this dirty water would burn out in a short time, while the twisting and strains of moving across the rough ground soon loosened boiler stay bolts. In addition, the cast iron traction gears used in early engines weren’t strong enough to withstand the strains of plowing and often broke. Those factors set the stage for the first showdown between external combustion and internal combustion engines.
