CHOPPING CORN STALKS AND LIKE CROP RESIDUE

摘要

A method of lifting corn stalks from a field surface and chopping the corn stalks with a rotary mower comprises configuring blades of the blade assembly such that as the blade assembly rotates, air is drawn upward under the mower deck; configuring the rotary mower such that an area of a circle defined by a circular path of outer tips of blades of the blade assembly is greater than 60 square feet; and rotating the blade assembly such that the outer tips of the blades move at a speed greater than 20,000 feet per minute and such that the air drawn upward under the mower deck draws corn stalks up from the field surface into contact with the blades.
