Answer 2

Benjamin Holt was an American inventor who developed Richard Hornsby's design for one of the first practical caterpillar tracks for use in tractors. The caterpillar type track is used to spread the weight of heavy agricultural and engineering vehicles out over a large area to prevent the vehicle from sinking into the mud.

Sinking into the mud was a common problem in peat soil surrounding Stockton, California where Holt made his residence. Caterpillar tracks allowed practical cultivation on an industrial scale on the rich peat land.

Holt formed The Holt Manufacturing Company in the early 20th century. Caterpillar tracked tractors were credited as providing some inspiration for the invention of the tank. Later, after Benjamin Holt's death, the Holt Manufacturing Company merged with C.L. Best Tractor Co. to form the Caterpillar Tractor Co., which is now Caterpillar Inc. The Holt tractor was constructed under the Caterpillar banner as the Caterpillar 60.
