The cast-iron plows used in the eastern US were designed for light, sandy soil. The rich Midwestern soil clung to the plow bottoms and every few steps it was necessary to scrape the soil from the plow. The steel plows were able to work the soil, leading to more successful farming settlements in the midwest.

It is proposed that this is a natural form of societies development, from earlier stages of development. In "Tribal" societies you had 3 basic classes, the "Young" who were unable to work (produce) the production class (middle age) and the old who produced less, but knew more. In Middle Aged societies you often found "Caste" based systems, as in lower class people who handled all the necessary grudge work (cleaning sewers, dealing with the dead, etc.) the 'production' class (craftsmen: blacksmith's etc), and then the 'ruling' class. Its necessary to understand "money" at this point, as between these two types of society the biggest change was the creation of money; pre-money it was a barter system, then the transition was the creation of 'bills' for trade. To detail this by example - pretend you had Chickens and wanted to trade for a Plow, but the man with the Plow wanted a Cow. It just so happens the man with the Cow wants Chickens, so, you get a "bill" - "Good for one Cow" and give him your Chickens, take the "bill" to the man with the Plow - and everyone is Happy. This system was refined to eventually create money. When you combine the "Caste" type system with a "Money" type system (as society naturally progresses) you end up with the 'classes' you asked about. Although there is a lot of argument about what defines each class, it is in all essence a antiquated classification system of a primitive society (that we are still dealing with).
It helped them with farming.
an iron plow is a farming tool that was used in India
An iron plow is made of iron, which is a softer metal compared to steel. A steel plow is made of steel, a stronger and more durable material than iron. Steel plows are generally more effective for breaking up tough or rocky soil compared to iron plows.
