  • Patent number: 4730721
    Abstract: A harvester of the riding type for tobacco or other leaf crop plants grown in parallel rows. The harvester comprises a vehicle of suitable height and width to span several plant rows. Primers' stations are suspended from the vehicle at a height from the ground suitable for the harvesting of the crop plants. One station is provided for each row. The vehicle has a platform positioned above plant height for an operator who manually transfers harvested leaves to a container located on the platform from conveyors provided at each of the stations for raising the leaves to the platform. The conveyors are positioned to partially surround the container at evenly spaced locations in order to minimize the total distance moved by the operator between the conveyors and the container. The vehicle has a lifting device used to interchange the container, when full, with an empty container and to unload the containers at the end of a row of plants.
