Before this came the grain elevator in 1840’s.it was used in separating the grain from the wheat plant. Soon the cotton gin followed which was used to separate the seeds and the hulls and the other stuff not required from the cotton. This was quite a successful agriculture invention. Man also developed the corn picker.

The most revolutionary agriculture invention was the Tractor which was invented in the 1940’s.this was the time when hand power was transformed into machine power. The tractor took over all manual work which used to take lot of time and energy of the farmers this agriculture invention took farming to a different level.

To add on major agriculture inventions fertilizers were developed in early 1900’s. This accelerated the growth of the crops and produced very healthy crops too. A little later peticides were also produced which helped in killing all the harmful pests which destroyed the crops so this invention brought in a lot of development in agri-products. Open geared gas tractors were also made during this time. Disk harrow which is a machine used to cut the grain stubble which is left behind in the field after harvesting is over was also a big agricultural invention. This saved a lot of manual labor and time too as a machine can work much faster than humans.
