With its horizontal shaft section, the vibrator shaft engages a rotary bearing of a vibrator hurdle. The two shaft ends are rotatably located in outer bearings of the mower-thresher machine frame. In the central longitudinal area the shaft is supported by an additional bearing against the machine frame. The central bearing (7) of the vibrator shaft (1) is arranged in a horizontal shaft section (1a) under a vibrator hurdle (2). This bearing is arranged directly in connection with the transition arc from the inclined to the horizontal shaft sections (1b,1a) in the horizontal shaft section (1a) and outside the width-halving end of the vibrating hurdle (2) located on the same shaft section (1a). USE/ADVANTAGE - To improve the support of a vibrator shaft in a mower-thresher machine.
