ABSTRACT:
A pair of conditioning rolls is disclosed that comprise one steel and one rubber/urethane roll. The steel roll has raised ribs formed thereon or attached thereto in a spiral configuration, while the rubber/urethane roll contains grooves therein that intermesh with the raised ribs during operation to grip the crop material. The smooth areas of the rolls crush the crop stems. Alternative embodiments of the grooves provide the ability to work within a wide range of crops, including crops that have heretofore proven difficult to condition.
