ABSTRACT:
A tobacco protecting harvester of the floating spear type disturbs the plants a minimum amount but positively controls them at all times, while severing and loading them onto tobacco sticks in respective groups and offloading the loaded tobacco sticks. Passing down a row the advancing harvester (a) touches each successive plant at the base of the stalk with a first trigger causing a leaf lifter to raise the forward lower leaf out of the path of a rearward-urging stop-and-start conveyor, (b) touches the plant at the base of the stalk with a second trigger behind the first trigger causing the conveyor to urge the plant rearward onto a spear just as a saw severs the base, (c) urges the plant rearward along the spear and onto a tobacco stick and then (d) when the first-loaded plant strikes a third trigger indicating a full stick, offloads the tobacco stick with the plants still upright so that they fall as a group from stump-height gently to the ground and are tipped over on a side for later pickup; mechanisms guiding the plants include intake belts, vertical-axis rollers at the spear point and an endless belt on one side balancing the leaves; a novel floating support system holds the spear more stiffly by grasping the ends during spearing; a loaded stick ejector mechanism coacts with a hinged-sidewall socket at the spear butt and at the stick rear-support; positive valve control trigger-mechanisms and compact flotation and propulsion provisions are also disclosed.
