USA HISTORY

Detailed explanation-1: -The steel plow of 1837, developed by John Deere, was an invention that contributed greatly to the agricultural world. It allowed farmers to cultivate crops more efficiently because the smooth texture of the steel blade would not allow the soil of the Great Plains to stick as the cast iron plow did.

Detailed explanation-2: -The earliest ploughs with a detachable and replaceable share date from around 1000 BC in the Ancient Near East, and the earliest iron ploughshares from about 500 BC in China. Early mould boards were wedges that sat inside the cut formed by the coulter, turning over the soil to the side.

Detailed explanation-3: -The plows being used by pioneer farmers of the day were cast iron, cumbersome and ineffective for cutting and turning the prairie soil. To alleviate the problem, Deere designed a plow of cast steel; it had a moldboard that allowed it to cut through heavy soil without having the soil constantly adhering to the plow.

Detailed explanation-4: -The steel plow was invented in 1837 by John Deere. By the 1870s larger plows with more blades and which were ridden became common. The plow is the first basic tillage tool.
