ABSTRACT:
The present invention relates to a defoliator head for a tobacco harvester in which the defoliator head is provided with a positive stalk gripping assembly for engaging and substantially encompassing respective tobacco stalks passing through the defoliator head during harvesting. The positive stalk gripping assembly comprises a pair of hydraulically driven belts disposed in side-by-side relationship so as to define a stalk passing area therebetween, and wherein at least one said belts includes a continuous series of outwardly projecting lugs disposed on the outside thereof. As the belts are driven, stalks entering therebetween are engaged and substantially encompass by the belts and successive lugs. Consequently, the stalks are stabilized and generally held in a firm upright position while the leaves are being defoliated therefrom by a defoliator mechanism associated with said defoliator head.
There is also provided a hydraulic speed control system that continuously effectively senses or monitors the ground speed of the harvester and drives the stalk gripping belts such that the horizontal rearward speed of the lugs is generally equal and opposite the harvester ground speed.
