What was the main impact of cyrus mccormick's reaper and john deere's steel plow on agriculture?

CYRUS MCCORMICK'S INVENTED MECHANICAL REAPER. THE MAIN IMPACT OF THE MACHINE WAS USED BY FARMERS TO HARVEST CROPS MECHANICALLY. THIS MACHINE GAINED FARMERS TO HARVEST CROPS QUICKLY AND TO SELL THINGS FASTER WITH A HUGE BULK THOSE DAYS. JOHN DEERE'S INVENTED A STEEL PLOW, WHICH PLOWS THE FIELD FASTER AND EASIER. THIS PLOW ALLOWED FIELD WORKERS TO NOT HAVE TO CLEAN OF SOIL ON THE PLOW BECAUSE THE STEEL WAS POLISHED AND WENT THROUGH THE PRAIRE DIRT FASTER THAN A REGULAR PLOW. THIS STEEL PLOW MADE JOHN DEERE POPULAR AND PRODUCED MANY STEEL PLOWS THOSE DAYS.
