The McCormick Reaper was important because it was a timesaving invention that allowed farmers to more than double the size of there crops. and was one of the grea â¦ test industrial establishments in the united states.
After Robert gave up, his son, 22-year-old Cyrus McCormick, reconfigured his father's experiments and had a working reaper ready in 1831. The machine was patented in 1834 and Cyrus made and sold copies from the Virginia plantation where he was born, but business was not good. By 1846, less than 100 had been sold. A meeting with Illinois senator Stephen A. Douglas and a visit to the vast grain fields of the Midwest convinced McCormick to relocate his operation to Chicago in 1847. His first investor was William Ogden.
