Abstract
A plant harvesting machine is organized as a wheeled tricycle having a plant elevator, plant inverter assembly, and plant sticking assembly and designed to move along a row of tobacco plants and successively harvest the plants. The plant elevator includes a powered circular saw blade at its base that severs the stem of each successive plant as the plant is gripped between opposed spike chains of the plant elevator. The severed plant is carried by the plant elevator and transferred to a plant inverter assembly that inverts the plant. The plant inverter assembly includes a spike-plate and cooperating pressure plate assembly that inverted the plant. The pressure plate assembly includes a spring-loaded pressure plate that accommodates plant stems of different diameters and shapes as the plant is inverted. Another set of spike chains engage the inverted plant and impale the plant onto a spear-shoe that is carried on a wooden stick. When a full complement of plants is mounted on a stick, the stick and its plants are discharged from the plant harvesting machine.
