Drive motor size and energy costs are reduced in a bidirectional vibratory conveyor that includes a bed (10) with an elongated generally horizontal conveying surface (16) terminating an opposite ends (12, 14). Isolation springs (26) mount the bed (10) above the underlying terrain (32) and a vibration inducing assembly (40) that includes a rotatable shaft (56) and an eccentrically mounted weight (58) is mounted to the bed (10). A pair of generally horizontally acting, vibration amplification systems (72) are mounted on the bed (10) and sandwich the vibration inducing assembly (40). Conveying direction can be reversed simply by reversing the direction of rotation of the motor shaft (56).
