Description
Knapp Plow Company
Background
The plows manufactured by the Knapp Plow Company contributed significantly to the agricultural history of the Santa Clara
Valley. The life of the company began in 1871 in Half Moon Bay, CA when Robert I. Knapp (1833-1904) built his first plow.
During that time, many farmers were growing potatoes on the hills along the coast. They plowed the sides using a Kilgore
reversible plow (sometimes called sidehill plow), with a cast iron bottom, which was found to be problematic and ineffective.
