An Explosion of Engineering Innovations

By: Dave Mowitz

The years before and after World War I were a remarkable time of engineering innovation for the materials and components of tractors.

The componentry and metallurgical advances from the 1900s to 1920s were significant for tractors. Among the innovations were lighter and stronger metals and engines that generated more power but were smaller in size and weight. Improved transmissions offered an increasing number of speeds delivered by gears that meshed smoothly in operation. Electrical systems generated a reliable spark to the engine and constant power for such advances as lighting and cooling systems that kept hard-working engines chilled. There were also devices that scrubbed dirt from the air, or precisely doled out fuel and general mechanical components, and fasteners that were lighter yet more durable.
