An improved tobacco leaf conveyor arrangement for a mobile tobacco harvester which comprises in combination: a. an endless conveyor surface that is disposed on a tobacco harvester, the ascending portion of said endless conveyor extending rearwardly and upwardly to a leaf discharge point, the descending portion of the endless conveyor extending from said discharge point downwardly and forwardly to a point where it can receive leaves for lifting; b. a first roller means mounted so that its periphery will press against the descending portion of the conveyor at a point near the leaf discharge point of the conveyor, c. a second roller means mounted adjacent to and above said first roller means and with its periphery pressed against the periphery of said first roller means in a driving relationship, said second roller means being located closer to said leaf discharge point of said conveyor surface than said first roller means, whereby said second roller means will rotate in a direction opposite to the direction of movement of the descending portion of the conveyor surface to thus assist in disengaging leaves from said conveyor surface adjacent said discharge point.
