  • Patent number: 7305812
    Abstract: A deleafer apparatus including a drum assembly partially enclosed by a shroud. A rotating blade assembly is located within an interior volume of the drum assembly. An air circulation device, located beneath the drum assembly, draws air through an opening defined by the shroud and into the interior volume of the drum assembly. In use, the deleafer apparatus is carried by a transport in a direction of travel along a row of plants or vines. The rotating blade assembly strips leaves that extend into the interior volume of the drum assembly from the plants or vines. The deleafer apparatus also includes a break-away mechanism that permits a portion of the deleafer apparatus to rotate outward relative to a transport mounting to accommodate obstacles that may reside in the pathway of the plants or vines.
