Abstract

Abstract A tracked vehicle is disclosed having forwardly extending conveyor chains for picking up a windrow of cane, lifting the cane and agitating the cane with agitator rollers to dislodge loose leaf or trash particles with the cane being fed through parallel cooperating segmentizer rolls to be chopped into short segments. Chopped cane falls through an air blast path for removing the trash and leaf particles and lands on the lower end of an outfeed conveyor extending transversely from the vehicle. The upper end of the outfeed conveyor has a conveyor end shroud in which fans are provided creating a draft across cane falling from the upper end of the outfeed conveyor onto a plurality of parallel agitator rolls which dislodge any remaining leaf or trash particles to be blown away by the fan in the conveyor end shroud with the cleaned cane segments then falling into a receiving trough or the like.
