The Seed Drill
Jethro Tull was born in Basildon, England. in 1674 Jethro was a major pioneer in the development of agriculture. Jethro Tull followed in the steps of his father and became a farmer. Tull worked at a place called Howberry farm, where he created the seed-drill which could sew three rows of seeds simultaneously. Later, he devised a horse-drawn hoe to clear away weeds. In 1731, Tull published his ideas about farming and plant nutrition. Despite initial resistance to Tull's revolutionary ideas, they were eventually adopted by large landowners, and in time formed the basis of modern agriculture. Tull died on February 21, 1741.

The McCormick Reaper
Cyrus McCormick was born on February 15th, 1809 in Rockbridge County, Virginia. While McCormick was a young man, his father was unsuccessfully trying to build a harvesting device. McCormick took over the job when his father gave up after fifteen years. Fortunately for McCormick, he had learned from all his father's mistakes, and in 1831 he successfully built his first harvester. It could harvest an acre an hour compared to the rate of half an acre a day that is accomplished by hand. Even with these statistics, other farmers thought the harvester a joke, possibly from its ridiculous looking frame. To get people's interest, McCormick decided to continue his work on the machine by making such additions as a blade so that the crops could be cut cleanly. In 1843, McCormick's machine won in a contest with another man's harvester due to McCormick's machines ability to harvest in rain (it rained the day of the contest). This peaked people interest, and McCormick made an annual sale of twenty-nine Cyrus Reapers (he named the machine after himself). In seven years, that annual sale would rise to five thousand a year. McCormick died at age seventy-five in 1884 and is credited as the inventor of the Cyrus Reaper.
