In 1837, which blacksmith modified the moldboard plow?

The modification of the moldboard plow in 1837 is attributed to John Deere, a blacksmith who created a steel plow that significantly improved farming efficiency. His innovative design was crucial for breaking the tough, sticky soil of the Midwest. Deere's plow was constructed out of steel rather than the cast iron or wood commonly used at the time, which allowed it to cut through soil more effectively and reduce the number of times a farmer had to stop and clean the blade during use.

John Deere's advancements in plow technology played a vital role in the agricultural development of the United States, particularly in areas with challenging farming conditions. This contribution greatly enhanced farming productivity and laid the groundwork for the future of agricultural machinery. Other historical figures listed, like Henry Ford, Eli Whitney, and George Washington Carver, made important contributions in their respective fields, but none were directly associated with the modification of the moldboard plow in the context of this significant advancement. Ford is known for pioneering assembly line production, Whitney for the cotton gin, and Carver for his work with crop rotation and peanut products—all distinct from Deere's contribution to plowing technology.
