A tobacco harvester comprises a pair of counter rotating defoliators overlying a pair of opposing spaced apart lateral transfer conveyors for conveying picked leaves outwardly from under the defoliators. A pair of belts are driven in opposite directions, portions of which oppose and are spaced apart from one another along opposing portions of the pair of lateral conveyors. The belt spacing is such to allow tobacco plant stalks to pass therebetween as opposing belt portions engage and support tobacco plant stalks. Side conveyors receive picked leaves from the pair of lateral transfer conveyors. The speed drives are arranged so that the rotary speed of the rotating defoliators, the conveying speed of the lateral conveyors, the conveying speed of the side conveyors and the linear speed of the belts are independently adjustable of one another. A pair of speed indicators may be provided to visually indicate the respective speeds of the picking rate of the defoliators and the ground speed of the harvester. The control devices are accessible to an operator while operating the harvester to permit matching of the two speeds to accomplish efficient mechanical tobacco priming and thereby reduce field loss and leaf damage.
