The Silver King tractor brand was created when manufacturer Fate-Root-Heath found itself in a battle with Chrysler over the Plymouth brand name. Fate won the fight, having built Plymouth-brand vehicles long before Chrysler, but sold the name to the automaker. Taking a cue from the silver paint on the tractors, the Silver King brand was born. Silver King tractors could be considered utility/industrial tractors ahead of their time, and were popular with factories. The Silver King tractor line was sold to Mountain State Fabricating in 1954 as parent company Fate-Root-Heath sought to focus on their locomotive business. Mountain State had only a brief production run before closing and the Silver King line ended.
