What did Jethro Wood invent?
iron plow
What did the steel plow replace?
Overall the steel plow replaced the wooden plow, steel being alot stronger material than wood but it was unable to be shaped into a plow bottom until the 1800s.
Why was the steel plow invented?
Prior to the Steel (or iron) Plow, plows were made of wood. If you hit a buried rock, or even a large root, you could break the plow's blade. Thomas Jefferson was the first to work out the exact proper angle of the mouldboard of a plow, (the curved part of the plow that turns the soil) Charles Newbold acquired a patent in 1797 for the first cast iron plow. David Peacock followed in 1807 with a couple similar designs that resulted in a successful patent infringement suit by Newbold against him. Blacksmith Jethro Wood acquired patents for two (three-part) cast iron plows in 1814 and 1819 that revolutionized the industry, making interchangeable parts a reality. The first self-polishing steel plow, the Grasshopper Plow, was invented by John Deere in 1837. This made tilling prairie land finally possible.
Why was the iron plow invented?
THE iron plow was invented to help the cotton production increase. That's baloney. Iron plows helped produce more food. The Cotton Gin helped the cotton production increase. Think about it. Cotton doesn't need digging into the soil. Potatoes do. I'm pretty sure the reason the Iron Plow was invented was because in 1797 Charles Newbold realized that wooden plows are stupid and that iron would be a much smarter alternative.Yes I realize that Jethro Wood made the first cast-iron plow with replaceable parts, but Newbold thought of the iron plow first. -------------------------- Used to make long straight rows for rice and soybeans, the iron plow was found in the northern part of Central China and dates around 475-220 BC. Early plows were small and handheld. Animal drawn plows appeared around the 1st century BC. Europe had iron plows around 1000 A.D. In the 1600's, improved iron plows were brought to Holland from China and might be credited for the beginning of the Agricultural Revolution. the first completely iron plow was developed sometime in the 1700s, but farmers were worried about iron poisoning the soil. In 1837, John Deere made it out of steel
Why is concrete better than wood?
concrete is better than wood because concrete is much stronger and that's why most of the building are made out of it
How was an iron plow better then that of wood?
iron is stronger than wood, so an iron plough would last longer than a wooden one.

How was john deers plow an improvment over earlier plows?
JOHN DEERe's improved on Jothero Wood plow because he made a plow that had replaceable parts, but John Deere made a plow that he invented. His plow was a lightweight steel plow. But each plow had an heavy iron or wooden handles that was held on by slow-moving oxen's, or a horse. But they mostly used Horses back than because the Horses can get the field plowed quicklier than the slow-moving oxens.
Who invented iron plow?
The iron plow was invented in the Zhou Dynasty. The farmers back then, bought iron plows and hooked them on to the farmers horses. Then the farmers had the horses pull the plow and them. The iron plow was invented between 1000 and 1028 BC.

What did John deere do?
He invented a better plow out of steel because the wood ones were always breaking.
On a cold winter day why would iron feel much colder to touch than wood?
The thermal conductivity, and thermal capacity of iron is a lot higher than for wood. So when you touch wood, a little heat from your finger warms the wood just at that place and isn't conducted away. But for iron, it's as though your finger is trying to heat the whole piece, the heat conducts away rapidly and your finger then keeps trying to supply more until it is as cold as the iron. So the iron feels colder - just because it doesn't warm under your finger like the wood.
What was the impact of the plow?
Metal tools lasted longer and worked better, and the growing of crops was improved by the idea of an ox-lead plow fitted with an iron tip on the end. Later, a tool was put on the plow that looks like a funnel to make seeding easier. Mechanical improvements of regular wooden plows started in the mid-1600's with little iron tips connected to the wood using strips of leather. In 1797, another blacksmith, Charles Newbold, created the cast-iron moldboard plow. In the 1830's, a man by the name of JOHN DEERe (an American blacksmith), improved the plow and built it with steel instead of wood. By the late 1800's, steam powered machines were used more and more rather than using animal-drawn plows and grain-harvesting machines. Steel plows helped farmers because they didn't have to stop and clean the dirt out of their plows.

Does wood have iron in it?
Wood does not contain iron other than as an incidental contaminant; the main component compounds in wood are cellulose and lignin.
What was the benefit of jethro wood's cast iron plow?
it helped the farmers with planting seeds and making trenches to plant the seeds.. it was also made because he wanted to make a change and give people a plow that woulnt break
What was used before the steel plow?
Before the steel plow, farmers used wooden plows or tools made of iron. These plows were heavier and less effective at breaking up tough soil compared to the steel plow invented by John Deere in the 19th century.
