The present invention relates to a pull type multi-pass automatic tobacco harvester adapted to be connected to a farm tractor and pulled through a tobacco field for harvesting tobacco within the field. The pull type automatic tobacco harvester includes a main frame that supports a leaf defoliator assembly and a conveying system on each side thereof for receiving the defoliated tobacco leaves and conveying them to an area of collection. Connecting the harvester to said tractor is a hydraulically actuate swingable tongue that is pivotably mounted about the front portion of said harvester's main frame. When pivotably connected to a draw bar on the tractor, said tongue may be pivoted such that the trailing position of the harvester can be laterally varied relative to the tractor such that the defoliator assembly of said harvester can be properly aligned with any one of two adjacent tobacco rows that run along one side of the tractor. To improve the row tracking capability of the pull type harvester of the present invention, the defoliator assembly is pivotably mounted about a longitudinal axis on said main frame and pivotable laterally back and forth about this longitudinal axis. This allows the row passing area defined within the defoliator assembly to shift laterally with the row being harvested due to variances in row spacing, crooks and curves in the row, and the imprecise positioning of the harvester about the row being harvested.
A method of harvesting tobacco in a field having a plurality of laterally spaced rows throughout the field with at least one skip row provided at intervals within the field for allowing a tractor to pass therethrough, wherein said method of harvesting tobacco utilizes a pull type automatic harvester having a main frame having ground engaging means mounted thereto for supporting said main frame and allowing the same to move on the ground during the harvesting operation, said ground engaging main frame being connected to a tractor that is adapted to move through respective skip rows within the field and to pull said ground engaging main frame of the harvester therebehind through the field during the tobacco harvesting operation, said method comprising the steps of:
A method of harvesting tobacco with a pull type automatic tobacco harvester having a main frame, including ground engaging wheels for allowing the same to move over the ground during the harvesting operation, operatively connected to a tractor in a tobacco field wherein throughout the field a series of tractor passing areas is provided with each tractor passing area being flanked on each side by two or more rows, the rows running directly adjacent the tractor passing area being referred to as outside rows and each row adjacent and outwardly of said outside row on the opposite side of said tractor passing area being referred to as an inside row, the method of harvesting outside and inside rows flanking a particular tractor passing area comprising:
A method of harvesting tobacco in a field having a plurality of laterally spaced rows throughout the field with at least one skip row provided at intervals within the field for allowing a tractor to pass therethrough, wherein said method of harvesting tobacco utilizes a pull type automatic tobacco harvester having a ground engaging wheel means mounted thereto for supporting said main frame and allowing the same to move over the ground during the harvesting operation, said ground engaging main frame being connected to a tractor that is adapted to move through respective skip rows within the field and to pull said harvester therebehind through the field during the tobacco harvesting operation, said method comprising the steps of:
