Sweet corn machine

The mechanical picker snaps the ears from the stalk so that only the grain and cobs are harvested. The standing stalks are guided by shields or snouts to pass between counter-rotating rollers that pull the stalks down and through very sharply, snapping the ears free.The cultivation of corn can be traced back 8,000 years to Central America. Sweet corn cobs have been discovered in Mexican caves from thousands of years ago. Mesoamericans chose to grow teosinite plants, an annual grass with small amounts of edible product.Sweet corn is mechanically harvested by self propelled or tractor pulled harvesters. With mechanical harvest, the part of the stalk that contains the ears is cut by the harvester and the ears are subsequently removed either by the harvest machinery or by hand.
