A tobacco harvesting machine for cutting tobacco leaves from the stalk of the tobacco plant. The machine has a self-propelled frame which is formed with the passage through which the plants pass as the frame moves along a row of plants. The machine provides an upward draft of air about the plant as it enters the passage in the frame so that the tobacco leaves are all lifted upwardly by the air draft to be disposed parallel to the stalk of the plant. The leaves are clamped against the stalk when in this upwardly directed position by means of conveyers which are mounted on the frame and located on opposite sides of the passageway. An assembly of cutter blades are mounted in the frame so as to provide at least three upstanding cutting edges which are operable in response to movement of the tobacco plant through the passage to provide cutting actions disposed in planes which are spaced about 120 DEG relative to one another so that as the frame moves relative to the stalk of a plant, any stems which are located within the path of any of the cutter blades will be cut. The cutter blades are mounted so as to pivot relative to their mounting in the event that the cutting edges strike a member, such as a sucker, which cannot be cut by the blades during the forward movement of the frame. The harvesting machine is also provided with conveyers for conveying the cut leaves to the storage receptacle in a manner such that all of the stems of the leaves are disposed generally parallel with one another and the cut ends are all located at the same end of the stack of leaves.
