JOHN DEERe invented his polished steel plow in 1837. Not sure if or when he made any cast plows though...
1837
Any sane person has to ask....WHAT?!?! He invented the first sucessful polished steel plow in 1837 but he NEVER invented the first cast steel pillow.
John Deere invented the polished steel plow in 1837 out of a broken sawmill blade.
John Deere did not invent the first cast steel pot. You may wish to re examine what your question really is.
1837
John Deere invented the cast steel plow during the 1800s. He found that a cast steel polished and correctly molboard (plow blade) could cut through the sticky clay of the midwest.
John Deere invented the self-polishing (scouring) steel plow. This invention made it much easier for farmers to plow the loamy, sod of the Midwest. John Deere was also a blacksmith by trade and had a very inventive mind. John Deere the company has invented many products over the years, varying from cotton picking machines to GreenStar GPS systems. For the 'rest of the story' see the related link...

The steel plow breaks up tough soil without the soil getting stuck to it. JOHN DEERe invented the steel plow because farmers in the Midwest could not use the cast-iron plow because they kept breaking. The Midwest soil was unlike the Northeast soil, and the cast-iron plow was made for the Northeast farmers to use.
