ABSTRACT:
A tobacco harvester includes a self-propelled vehicle frame having driven front wheels and steerable rear wheels. A pair of harvester units are positioned side-by-side on the frame and each unit includes mechanisms for harvesting a row of tobacco plants. Each unit includes a tobacco stalk gripper which conveys a stalk into a cutting blade and which cooperates with an impalement conveyor to impale a stalk onto a tobacco stalk spear positioned longitudinally of the subframe. The impalement conveyor transfers the stalks to one or more stalk conveyors which slide the stalks along the spear toward a stick loading conveyor. The stalk conveyors are operated to time the travel of the stalks between the cutter and the stick loading conveyor. The stick loading conveyor is positioned opposite a stick supplier or magazine which holds a supply of tobacco sticks. A stick positioner receives the sticks one at a time from the magazine and places them on the stick loading conveyor aligned with the stalk spear. When the required number of tobacco plants have been impaled on the tobacco stick, the stick loading conveyor pivots rearwardly to orient the loaded stick vertically. A punch mechanism forms a hole in the ground, and a stick setting mechanism transfers the loaded stick from the stick loading conveyor to the hole and releases it.
