Cyrus McCormick was not satisfied to let well enough alone. He spent nine more years in making his reaper do everything just right before he was willing to sell it. The farmers admired the clever machine, but they were not ready to buy it, because they thought it would take work from many laborers. The money panic of 1837 occurred during this time, and young McCormick went into the iron-smelting business to make a living during the hard times.
