Charles Newbold. Charles Newbold (1764–1835) was an American blacksmith born in Chesterfield, New Jersey. On June 26, 1797, Newbold received the first patent for a cast-iron plow. However, he was unable to sell his plow because many farmers feared that the iron in it would poison the soil. [1]
In 1837, Deere developed and manufactured the first commercially successful cast-steel plow. The wrought-iron framed plow had a polished steel share. This made it ideal for the tough soil of the Midwest and worked better than other plows. By early 1838, Deere completed his first steel plow and sold it to a local farmer, Lewis Crandall, who ...
A plough or (US) plow (both pronounced / plaʊ /) is a farm tool for loosening or turning the soil before sowing seed or planting. [ 1 ] Ploughs were traditionally drawn by oxen and horses but modern ploughs are drawn by tractors. A plough may have a wooden, iron or steel frame with a blade attached to cut and loosen the soil.
Henry Burden (April 22, 1791 – January 19, 1871) was an engineer and businessman who built an industrial complex in Troy, New York called the Burden Iron Works. Burden's horseshoe machine, invented in 1835, was capable of making 60 horseshoes a minute. His rotary concentric squeezer, a machine for working wrought iron, was adopted by iron ...

Born in Springwater, New York, and living his adult life in Beaver Dam, Wisconsin, he held more than 40 patents for farm machinery and agricultural implement improvements, including the patent on the cultivator tooth.
The entrance to the Oliver Chilled Plow Works in South Bend, Indiana, c. 1880. Another problem common to cast iron plow bottoms was the lack of soundness and uniformity in the metal's molecular structure, which meant that some cast iron bottoms would have soft spots in the hardened surface, reducing the wearability of the plow bottom.
Steels. Cast iron is a class of iron – carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. [1] Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: white cast iron has its carbon combined into an iron carbide named cementite ...
Metallurgy in China has a long history, with the earliest metal objects in China dating back to around 3,000 BCE. The majority of early metal items found in China come from the North-Western Region (mainly Gansu and Qinghai, 青海). China was the earliest civilization to use the blast furnace and produce cast iron.
