Abstract
The invention provides a harvester to harvest crops such as rows of corn. The invention provides independent drives and independent controls for gathering belts, and independent drives and independent controls for knife rolls used on a corn harvester. The independent drives and independent controls allow the speed of the gathering belts or the knife rolls to be varied without affecting other harvester components. The independent speed control between the gathering belts and the knife rolls, allow for better harvesting in various crop conditions. The invention also provides a means for changing the angle of the corn head to allow better harvesting under varying conditions.
