When did we start using heavy machinery to harvest our crops?

    The first real machinery used in agriculture was the cotton gin in 1793, but there was no equivalent with which to harvest other crops. The first equipment resembling modern machinery, a cast-iron plough, was first patented in 1797 but it didn’t catch on. In 1814 and 1819 the blacksmith Jethro Wood received two patents for his three-piece iron plow which sold much more widely than the older model. The first machine used to harvest crops on a large scale was Cyrus McCormick’s mechanical reaper in 1831.
