ABSTRACT:
A tobacco harvester includes a plurality of linearly spaced tobacco plant engaging flights attached to an endless chain at equal linear distances with the sensing of a tobacco plant at a first position resulting in a cycle of operation occurring to advance the plant from its first position to a second position just beyond the front end of a spear. The plant is centered by an upper driven belt and a lower non-driven belt between which the plant is advanced by one of the flights. A paddle wheel is rotated 180.degree. during each advancement of a tobacco plant from its first position to its second position and aids in advancing the plant between the two centering belts. When another plant is sensed at the first position, the first tobacco plant is advanced from its second position to a third position on a stick at the rear of the spear. As the plant is advanced along the spear, each of at least three pairs of pivotally mounted support arms is moved out of the way of the plant through another of the tobacco plant engaging flights acting on a separate switch for each pair. Each tobacco plant is advanced a selected distance along the stick during each cycle of operation until a selected number of the plants is on the stick. The stick with the plants is removed from its tobacco plant receiving position at the end of the stick when another stick is positioned for loading, either manually or automatically.
