TOBACCO COMBINE WITH SELECTIVE CONVEYOR RAISING ABSTRACT OF THE DISCLOSURE A tobacco combine comprising a frame operable to be moved along a row of tobacco plants in a tobacco field, a pair of cooperating power driven mechanical tobacco de- foliating units mounted on the frame for (1) movement therewith along the row of tobacco plants on opposite sides of a predetermined vertical extent of the stalks of the tobacco plants for removing tobacco leaves attached to the portion of the stalks within the predetermined vertical extent and (2) vertical movements with respect to the frame within (a) an operative range for varying the predetermined vertical extent of the stalks and (b) above the operating range for clearance purposes, a power driven longitudinal conveyor assembly disposed laterally outwardly from each defoliating unit for receiving leaves directed laterally thereby and moving the same rearwardly, a manually adjust-. able strut assembly for supporting the forward end of each longitudinal conveyor from the frame against a downward movement below a selected position of adjustment but per- mitting upward movement above the selected position of adjustment, and a lost motion connection operatively con- nected between the defoliator units and the forward end of each of the longitudinal conveyor assemblies for (1) enabl- ing power operated movement of the defoliating units vertically within the operating range without effecting any vertical movement of the forward end of either of the longitudinal conveyor assemblies and (2) effecting an up- ward movement of the forward end of each of the longitud- inal conveyor assemblies above the selected position of adjustment thereof in response to the upward movement of the defoliator units upwardly above the predetermined operating range of vertical movements thereof and by so doing to transfer the support of the front end of each of the longitudinal conveyor assemblies from the asso- ciated manually adjustable strut assembly to the lost motion connection thereby enabling the manually adjust- able strut assembly to be manually adjusted while out of supporting relation with the forward end of the associated longitudinal conveyor assembly.
