Abstract
A system for mounting and supporting cotton harvesting units for vertical displacement on a forward end of a cotton harvester frame. The mounting and supporting system includes a parallelogram-type linkage assembly for connecting the harvesting units to the frame such that the harvesting units maintain a generally level attitude in either lowered or raised positions. The linkage assembly includes vertically spaced and generally parallel lift arms and tension arms. Each lift arm and tension arm is pivotally attached at its rear end to the frame and at its forward end to the harvesting units. A tilting mechanism connects the rear end of the tension arms to the frame and is operable to move the harvesting units about their pivot attachment to the lift arm to a tilted position and thereby facilitate an increase in ground clearance for the cotton harvester.
