HOLT

Holt was an American inventor who developed the first practical caterpillar tracks for use in tractors. The caterpillar type track is used to spread the weight of heavy agricultural and construction plant out over a large area to prevent the vehicle from sinking into the mud. He acquired the patent from Richard Hornsby & Sons of England, in 1914.
