To all whom/zit may concern.-. Be it known that I, FRANK M. HINOHMAN, a citizen of the United States, residing at Waco, in the county of McLennan and State of Texas, have invented new and useful Improvements in Gang- Flows, of which the following is a specification.

Finally, in the Middle Ages, somebody invented the harrow. A harrow is a wooden board that attaches to a plow, and helps the plow really turn over the dirt instead of just making a groove in it. Then if you harrow the field crossways after you drop the seeds, you don't have to cover the seeds up one by one anymore.

While serving as minister to France, Jefferson had the opportunity to observe European plow designs. Their deficiencies inspired him to set down in a memorandum (1788) his plans for an improved moldboard, the wooden part of the plow that lifts up and turns over the sod cut by the iron share and coulter.

In 1814 Jefferson began to have his moldboards cast in iron. He informed Charles Willson Peale (21 March 1815) that the plow with his iron moldboard was so light that the two small horses or mules draw it with less labor than I have ever before seen necessary.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail,referring to the drawings, where the numerals 1 and 2 indicate two parallel side beams, the one 2 {,being at the .landside and extending the full length of the frame.

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.

Ipurpose using a seeder,located at the righthand side of the plow-frame in advance of the plows. I am aware of Letters Patent Nos. 331,503 and 283,391, and do not wish to be understood as broadly claiming what is therein disclosed. Having thus described my invention, what I claim is 1.

By 1794, Jefferson had put his plans into action at Monticello. He had a plow fitted with a wooden moldboard of his design and reported to Sir John Sinclair (23 March 1798) that an experience of five years has enabled me to say, it answers in practice to what it promises in theory..

But it's faster to use a plow. The simplest kind of plow is a digging stick with a handle on it crossways. You push it along through the dirt, so it makes a groove, and then somebody else goes along behind you dropping the seeds in here and there, and using her foot to cover up the seeds again loosely.

John Deere saves the day with a new invention! In 1837, Deere figured out a way to make things easier for western farmers by constructing a plow that was made of polished steel. Deere designed his first steel plow by taking an old steel saw blade and polishing it up.
