The horse-drawn machine that cut standing grain faster than a line of men with scythes, breaking the harvest labor bottleneck that had capped every farm's size since antiquity. Cyrus McCormick's 1831 machine and Obed Hussey's rival design opened the American grain belt; McCormick's company became the seed of International Harvester.

Why this is disputed. McCormick's claim is the famous one; Obed Hussey patented first (1833) and the priority dispute ran for decades. Recorded as debated, not smoothed.

Dissenting Readings (1 dissenting reading)
Developed By: Cyrus McCormick

When McCormick tried to renew his patent in 1848, the U.S. Patent Office noted that a similar machine had already been patented by Obed Hussey a few months earlier; McCormick later lost a court challenge to Hussey's patent.
