ABSTRACT:
The present invention entails a pull-type tobacco harvester having a mainframe, a tongue projecting from the mainframe, a defoliating unit mounted on the mainframe, and a conveyor assembly disposed adjacent the defoliating unit for conveying defoliated tobacco leaves from the defoliator unit upwardly and rearwardly to where the defoliated leaves are dumped into a trailing trailer. Disposed on one side of the mainframe is a single wheel while mounted to the opposite side of the mainframe is a pair of tandem wheels. The pair of tandem wheels are disposed so as to generally track behind a tractor that pulls the tobacco harvester through the field. In addition, the defoliator unit mounted on the harvester is a knife-type defoliator that comprises a series of bars that include knife elements thereon for cutting leaves from stalks of tobacco passing through the defoliator unit. The defoliator unit of the present invention includes a stalk guide structure in the form of a series of beads, with each beads being disposed on an inner side of a bar that carries the knife elements. Because the bead projects at least slightly inwardly from the bars, the beads act to guide tilted or blown over tobacco stalks generally to an upright position where the leaves thereon can be harvested efficiently without the knife elements cutting the stalks down.
